Frequently Asked Questions

Questions & Answers

Do I need a referral ?

Referrals can be obtained from your General Practitioner or your specialist for diagnostic procedures and consultations. This will outline the medical difficulties you are experiencing and gives the specialist an idea as to what has been happening with your Cardiac status.

You must obtain a referral BEFORE your date of procedure or consultation.

A  Specialist to Specialist referral remains current for 3 months only.

A General Practitioner referral remains current for 12 months only, unless specified by your GP.

It is necessary to have a valid referral for your appointment to allow you to claim from Medicare for your clinic visit.  This is the responsibility of the patient.

Do i have to make an appointment or can i walk in anytime ?

Our practice functions on an appointment basis, Please contact the us on 1300 693 246 or 9560 7558 to make an appointment. Walk-in patients are welcome if they are prepared to wait for patients with appointments.

How are diagnostic test results managed ?

Test results are only given to the patient concerned, these results may be given over the phone by an experienced practice nurse, however you will generally be asked to make an appointment with your Doctor to follow up.

What do I bring with me to the consultation ?

You should bring –      Your current referral from your GP.

Your actual current medications including drug name, milligram dosage and frequency.

If you have been seen by a Cardiologist before, then a copy of your previous correspondence/tests from that Doctor if you have this information.

What should I wear for my tests ?

You should always wear a two piece outfit. This will allow for the removal of the top half of your clothing.

For the Exercise Stress test – Two piece outfit – i.e. – comfortable clothing for exercising and comfortable closed in shoes suitable for walking on the treadmill.

For the Holter monitor – Two piece outfit to allow placement of ECG leads to the chest region for a 24 hour period.

For the Echocardiogram – You should wear a two piece outfit. This will allow for the removal of the top half of your clothing for the test.

If I or a friend or family member has chest pain, what should we do ?

Call 000 immediately. Do not drive yourself or your loved one to the hospital. If you are having a heart attack, the emergency medical service (EMS) team that comes to you will begin life-saving treatment on the ambulance ride to the hospital.

How do I change or cancel an appointment ?

We ask that you cancel or change appointments as soon as you know you have another commitment. Please be contact us 24 hours in advance between the hours of 8:30 AM and 5:00 PM, Monday thru Friday.

What support staff do we have to better serve you ?

Nurse Practitioners
Nurse Practitioners are certified by national regulatory agencies and are registered with the State of Connecticut Department of Public Health and Department of Consumer Protection. Working closely with the Cardiologists, they assist with initial evaluations, office visits, patient education and a variety of diagnostic tests.

Registered Nurses
The Registered Nurses on our staff assist with office tests/procedures, see patients in the various clinics and answer phone call concerning patient care.

Medical Assistants
Graduates from a medical assistant course, our Medical Assistants are responsible for preparing patients for examinations, as well as escorting individual patients throughout the office.

Cardiovascular Technicians
These specially trained technicians help the nurses and physicians perform Treadmills and Exercise Echocardiograms, connect and scan holter monitors, run ECG tests, and check pacemakers.

Echo Technicians
Echo Technicians use ultrasound to record images that help our physicians visualize and measure the internal structures of the heart. These images are preserved on disks so that our Cardiologists can review them at any time.

What is a Cardiologist ?

Cardiologists are doctors who specialize in diagnosing and treating diseases or conditions of the heart and blood vessels—the cardiovascular system. You might also visit a cardiologist so you can learn about your risk factors for heart disease and find out what measures you can take for better heart health. Texas Heart Institute cardiologists are listed in the professional staff directory.

When you are dealing with a complex health condition like heart disease, it is important that you find the right match between you and your specialist. A diagnosis of heart or vascular disease often begins with your primary care doctor, who then refers you to a cardiologist. The cardiologist evaluates your symptoms and your medical history and may recommend tests for a more definite diagnosis. Then, your cardiologist decides if your condition can be managed under his or her care using medicines or other available treatments. If your cardiologist decides that you need surgery, he or she refers you to a cardiovascular surgeon, who specializes in operations on the heart, lungs, and blood vessels. You remain under the care of your cardiologist even when you are referred to other specialists.

Cardiology is a complex field, so many cardiologists specialize in different areas. All cardiologists are clinical cardiologists who focus on the diagnosis, medical management (use of medicines), and prevention of cardiovascular disease. Some clinical cardiologists specialize in pediatric cardiology, which means they diagnose and treat heart problems in children. When clinical cardiologists treat only adult patients, they specialize in adult cardiology. Other clinical cardiologists may specialize in interventional procedures (balloon angioplasty and stent placement), echocardiography, or electrophysiology.

What does a Holter monitor tell me about my heart ?

A Holter monitor is a portable electrocardiogram (EKG) that monitors the electrical activity of an ambulatory patient’s heart for a 24-hour period. It is most often used when your physician suspects an abnormal heart rhythm, often based on complaints of a sensation of a beating heart, a fast heartbeat, or palpitations.

There is no special preparation for this painless test. Wires from the monitor are taped to the patient’s skin, and he or she is asked to go about usual daily activities. The patient keeps a diary so the physician can correlate the monitor’s results with the patient’s reported symptoms.

I think I am having a heart attack. What do I do ?

CALL 000 IMMEDIATELY. Emergency medical service teams are better equipped to handle active heart attacks. Chest pain can be a warning of heart disease–or it can be a symptom of a heart attack. Be aware of other possible symptoms: discomfort or pain going to the neck, back, jaw, arms, or shoulders; numbness or tingling in one or both arms; nausea or vomiting; shortness of breath; extreme fatigue; sweating; weakness, dizziness, or passing out; or indigestion (heartburn). If you or a loved one ever experience chest pain–especially if one or more of the other symptoms are also present–seek medical attention immediately by calling 000. Please have someone let our office know so we may assist and follow up with you after the emergency is over.

What is an echocardiogram of the heart ?

Also known as transthoracic (across the chest) echo, it is a painless test used to observe the heart chambers and valves. Not an x-ray, it uses ultrasound high frequency waves to get a picture of all four heart chambers and valves. The sound waves bounce back and produce images and sounds that can be used by the cardiologist to detect damage and disease.

An echocardiogram is a safe, noninvasive test, and in fact, is the same technology used to image a fetus before it is born. To perform the test, a special gel is placed on the chest wall and a transducer is then moved over the gelled areas to produce images for interpretation.

What is coronary artery disease ?

Coronary artery disease is a chronic condition that leads to the narrowing and hardening of the arteries that supply blood to the heart muscle. This narrowing leaves less room for blood flow, depriving the heart muscle. Many risk factors, smoking, diabetes, high cholesterol, high blood pressure, lifestyle, and family history, can contribute to the development of coronary artery disease. Aside from inherited factors, any of the risks can be modified and the chance of developing heart disease reduced.

How can I improve my HDL, or “good cholesterol," without taking medications ?

Consuming monounsaturated fats can improve your HDL as well as reduce triglycerides and bad cholesterol (LDL). These include olive oils and other vegetable oils, nuts and avocados. Some foods such as peanuts, green peas, sunflower seeds and corn can also raise HDL. Other important strategies to raise HDL include a regular exercise program, alcohol in moderation and the cessation of smoking. Calcium supplements have also been shown to increase HDL levels.

I have heard that red wine can help your heart. Is that so ?

Observational studies have shown lower risk of cardiovascular events in patients who regularly drink red wine. Since these early observations, several studies have suggested that it may be just the alcohol that confers these benefits, although there may be some benefit in the grape as well. Males who have two drinks a day and women who have one drink (beer – 12 ounces, wine – 5 ounces, liquor – 1 ounce) had a heart disease risk reduction of 30 to 50%. Still, the American Heart Association does not recommend alcohol as a means of risk reduction.

Alcohol consumption has been attributed to raising the “good cholesterol,” the HDL. Other beneficial effects may be blood thinning and, in certain patients, lowered blood pressure. Of course, in other people, blood pressure can be raised by drinking alcohol. Whether alcohol is good for you should be decided on a case-by-case basis with your physician. For people who do drink, the benefits seem be related to having their alcohol on a regular basis with a meal and not episodically. Moderation is the key – no more than two drinks for men and one drink for women, and regular follow up with your physician.

What is atrial fibrillation ?

Atrial fibrillation (A fib) is one of the most common heart rhythm disorders, affecting more than two million people in the United States. In A fib, the heart beats rapidly and irregularly. Although not directly life threatening, A fib can cause palpitations, other rhythm problems, chronic fatigue, shortness of breath, chest pain, dizziness and stroke. The chance of a stroke is increased five-fold in patients with A fib.

The likelihood of developing A fib increases with age but can occur in young patients as well. Treatment of A fib includes medications to establish normal rhythm, medications to slow the heart rate during A fib, and medications that thin the blood. Often A fib can be difficult to control. New procedures are now available which can cure A fib in selected patients.

I often feel like my heart skips a beat. Is this normal ?

One of the most common presenting complaints to a cardiologist is the complaint of a “skipped heartbeat.” Normal heart rhythm is dictated by the sinus node, the pacemaker of the heart, which resides in the top right cardiac chamber. The sinus node sends electrical impulses to the bottom chambers of the heart, the ventricles, through specialized conduction tissue. The resulting rhythm is regular – the top chambers, the atria, beat first followed by beating in the ventricles.

The sensation of skipped beats usually comes from extra electrical beats originating in the atria or ventricles. These extra beats are very common and can increase with stress or increased caffeine intake. As we get older, the frequency of these extra beats tends to increase. Generally, these extra beats do not represent a serious problem, but if they persist consultation with a physician is recommended.

What is a pacemaker ?

A pacemaker is a small device that is implanted in the upper chest region for prevention of an abnormally slow heartbeat. A slow heartbeat develops when the heart’s natural pacemaker slows down with age or when the heart’s natural electrical conducting fibers wear out. Patients requiring pacemaker implantation often complain of dizziness, lightheadedness, fatigue and/or fainting associated with a slow pulse.

Not uncommonly, patients who need pacemakers are on necessary medications that result in excessive heart rate slowing. A pacemaker system generally consists of a pulse generator, which houses the pacemaker battery and circuitry, and two pacemaker leads. The leads are inserted through the veins into the top and bottom chambers of the heart.

A typical pacemaker implantation is done under local anesthesia with light sedation and can be completed in 60 to 90 minutes. Patients with pacemakers can enjoy active, normal lifestyles with minimal restrictions. Most electronic devices in the environment, including microwave ovens, have no effect on pacemakers.

Is it normal to feel irritable or depressed after suffering a heart attack ?

It is not uncommon for persons to have strong emotional feelings after going through an ordeal such as a heart attack. Many times heart attacks occur suddenly in otherwise healthy people who aren’t accustomed to the idea to having to deal with any illness. Sometimes it triggers feelings of depression, hopelessness, irritability and fear.

Any patient struggling with these emotions after a heart attack should discuss them frankly with his or her physician. Counseling and medication can help remove this obstacle to good health. Enrolling in supervised cardiac rehabilitation after a heart attack can also be quite beneficial.

What causes cardiovascular disease ?

There are many risk factors that contribute to the development of cardiovascular disease.  Some people are born with conditions that predispose them to heart disease and stroke, but most people who develop cardiovascular disease do so because of a combination of factors such as poor diet, lack of physical activity and smoking, to name just three.  The more risk factors you expose yourself to, the higher the chance of developing cardiovascular disease.

Many of the risk factors for cardiovascular disease cause problems because they lead to atherosclerosis.

Atherosclerosis is the narrowing and thickening of arteries. Atherosclerosis develops for years without causing symptoms.  It can happen in any part of the body.  Around the heart, it is known as coronary artery disease, in the legs it is known as peripheral arterial disease.

The narrowing and thickening of the arteries is due to the deposition of fatty material, cholesterol and other substances in the walls of blood vessels. The deposits are known as plaques. The rupture of a plaque can lead to stroke or a heart attack.

What is cholesterol ?

Cholesterol is a waxy, fat-like substance used by the body to build cell walls and for making several essential hormones. Your liver produces cholesterol and you absorb it from the animal fats you eat.

Cholesterol is carried through the blood by particles called lipoproteins. There are two types: low-density lipoproteins (LDL) and high-density lipoproteins (HDL). The former carries the cholesterol around the body in the blood and the latter transports cholesterol out of the blood into the liver.

When cholesterol is too high, or the levels of the two types are out of balance (dyslipidaemia), the cholesterol can clog the arteries affecting the flow of the blood.

What are triglycerides ?

Triglycerides are fats found in the blood that are important for muscle energy.  They travel through the blood in lipoproteins. As triglyceride levels rise, HDL cholesterol levels fall. High levels of of triglyceride increase the risk for heart disease. In rare cases, very high levels can lead to pancreatitis. Conditions that may cause high triglycerides include obesity, poorly controlled diabetes, drinking too much alcohol, hypothryroidism, and kidney disease.

What is the connection between high blood pressure (hypertension) and heart disease ?

Blood moving through your arteries pushes against the arterial walls; this force is measured as blood pressure.

High blood pressure (hypertension) occurs when very small arteries (arterioles) tighten.  Your heart has to work harder to pump blood through the smaller space and the pressure inside the vessels grows.  The constant excess pressure on the artery walls weakens them making them more susceptible to atherosclerosis.

How is coronary heart disease diagnosed ?

There are a number of ways to diagnose coronary heart disease. Your physician will probably use a number to make a definitive diagnosis.

A coronary angiogram uses a dye inserted into your arteries and an x-ray to see how the blood flows through your heart. The picture taken, the angiogram, will show any atherosclerosis.

Another test is an electrocardiogram.  This test records the electrical activity of your heart.  An electrocardiogram measures the rate and regularity of heartbeats, the size and position of the heart chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart. It is a non-invasive procedure.

How are smoking and heart disease linked ?

Smoking damages the lining of blood vessels, increases fatty deposits in the arteries, increases blood clotting, adversely affects blood lipid levels, and promotes coronary artery spasm. Nicotine accelerates the heart rate and raises blood pressure.

Does diet play a part in the development of heart disease ?

Diet plays a significant role in protecting or predisposing people to heart disease. Diets high in animal fat, low in fresh vegetables and fruit, and high in alcohol have been shown to increase the risk of heart disease.

Adopting a diet low in fat and salt has a protective effect over the long term. This means whole grains, fruits, and vegetables.

Aren’t women protected from heart disease because of estrogen ?

Estrogen does help raise good HDL cholesterol so protecting women, but once through the menopause as many women as men are affected by heart disease: but if a woman suffers from diabetes or has raised levels of triglycerides that cancels out the positive effect of estrogen.

How do the symptoms of heart attack differ between men and women ?

The symptoms of heart attack in a man are intense chest pain, pain in the left arm or jaw and difficulty breathing.

A woman may have some of the same symptoms, but her pain may be more diffuse, spreading to the shoulders, neck, arms, abdomen and even her back. A woman may experience pain more like indigestion. The pain may not be consistent. There may not be pain but unexplained anxiety, nausea, dizziness, palpitations and cold sweat. A woman’s heart attack may have been preceded by unexplained fatigue.

Women also tend to have more severe first heart attacks that more frequently lead to death, compared to men.

Is heart disease hereditary ?

Heart disease can run in some families. But even if you inherit the risks factors that predispose you to heart disease, such as high blood cholesterol, high blood pressure, diabetes, or being overweight, there are measures you can take that will help you avoid developing cardiovascular disease.

How does the normal heart work ?

The normal heart is composed of four chambers. The two upper chambers (called atriums or atria) are reservoirs which collect blood as it flows back to the heart. From the atriums, blood flows into the lower two chambers (called ventricles) which pump blood, with each heart beat, into the main arteries. From the right side of the heart one of these arteries (the pulmonary artery) carries blood to the lungs for re-oxygenation. The left side of the heart pumps blood into the other main artery (the aorta), which takes blood to the rest of the body.

The two ventricles and the two atriums are separated by partitions called ‘septums’. The partition between the atriums is called the ‘atrial septum’ and the one separating the two ventricles is the ‘ventricular septum’. Dark red deoxygenated blood (shown blue in diagram) returns to the right atrium from the body through the two main veins called the ‘superior vena cava’ and ‘inferior vena cava’. It is pumped by the right ventricle to the lungs for replenishment with oxygen. The dark blood becomes bright red (shown red in diagram) in the lungs when oxygen is taken up. This red blood returns through two veins from each lung, to the left atrium and is pumped by the left ventricle to the body again.

The heart has its own internal pacemaker which controls its rhythmical beating. It creates an electrical impulse which causes firstly the atriums, and secondly the ventricles, to contract in turn. With each contraction the blood is pumped, then the heart muscle relaxes and the chambers refill with blood, ready for the next contraction.

What are the heart valves ?

There are four valves which control the blood flow through the heart. They all consist of two or three flaps which swing open to allow blood through with each heart beat, and swing closed to prevent blood going back in the wrong direction.

Deoxygenated (blue) blood returning from the body collects in the right atrium. It flows to the right ventricle through the ‘tricuspid valve’. It is then pumped through the ‘pulmonary valve’ into the pulmonary artery on its way to the lungs. Oxygenated (red) blood returning from the lungs collects in the left atrium and flows through the ‘mitral valve’ into the left ventricle. It is then pumped through the ‘aortic valve’ into the aorta and to the body.

Aren’t women protected from heart disease because of estrogen ?

Estrogen does help raise good HDL cholesterol so protecting women, but once through the menopause as many women as men are affected by heart disease: but if a woman suffers from diabetes or has raised levels of triglycerides that cancels out the positive effect of estrogen.

What is meant by the term 'congenital heart disease' ?

The phrase ‘congenital heart disease’ refers to the various abnormalities of the heart which are present at birth. Other words, such as disorder, defect, condition, or problem, may be used instead of disease.

There are three main types of abnormalities:

  1. There may be a narrowing (called ‘stenosis’) in parts of the heart, in its valves, or in the blood vessels outside the heart. This narrowing obstructs the flow of blood and puts strain on the heart muscle. In severe cases, the flow of blood past the obstruction may be reduced.
  2. There may be holes in the partitions (septums) between the chambers of the heart. These allow blood to flow from one side of the heart to the other (called ‘shunting’). As the blood pressure is higher in the left side, blood flows (shunts) from left to right and results in increased flow to the lungs. The normal communications present at birth may persist between the main blood vessels attached to the heart, e.g. Patent Ductus Arteriosus. This also results in increased blood flow to the lungs.
  3. The main vessels may be attached to the heart at an abnormal location.

In this abnormality, the aorta arises from the right ventricle and the pulmonary artery from the left ventricle. Thus the dark blood returning from the veins is pumped back into the main circulation, resulting in ‘cyanosis’ (blueness of the skin). In the newborn period, the ductus arteriosus and the foramen ovale are still open and allow some bright blood to get into the circulation. The baby will then usually survive for a few days at least, until effective treatment and surgery can be arranged. Note: In some cases a combination of abnormalities may exist.

In this heart abnormality the way into the lungs from the right ventricle is narrowed (Pulmonary Stenosis). Some of the dark blood passes through the VSD into the aorta, resulting in cyanosis (blueness of the skin). Some affected babies may appear normal for several weeks or months before the blueness begins to develop as the narrowing becomes more severe.

How common are congenital heart problems ?

Abnormalities of the heart are present in nearly 10 in every 1,000 babies born. Some of these are mild and cause no significant disturbance to heart function. In many cases, such minor problems need no treatment and do not affect the life or the health of the child. More serious abnormalities are present in about five of these ten individuals with congenital heart problems.

The total frequency of all birth defects affecting different parts of the body is quite high. Some abnormality occurs in about 25 in every 1,000 babies born. This, however, includes many minor abnormalities.

Why do congenital heart problems occur ?

In most cases the cause of the heart abnormality is unknown. By the end of the 7th week of pregnancy the heart is fully formed. It changes little in its basic structure until birth when the circulation of the blood alters as the lungs start to function. Major abnormalities in development of the heart must therefore occur early in pregnancy.

Parents will naturally worry about things which might have affected the formation of their child’s heart. In most cases the heart abnormality is only an unfortunate occurrence which has not resulted from any identifiable cause. However, in some cases there are genetic errors which are responsible for the problem. If this is at all likely you may be offered a consultation with a geneticist.

Some illnesses in a pregnant mother may result in abnormalities in her baby’s heart and vessels. One example is German measles (rubella), if contracted early in the pregnancy. Occasionally medications or alcohol taken during the pregnancy can cause problems – though small quantities of alcohol are not likely to cause harm. Many medications, which are needed during pregnancy for a wide variety of reasons and are prescribed by a doctor, do not lead to any damage to the baby. Smoking is certainly very undesirable during pregnancy, as it has adverse effects on growth of the baby and is associated with an increased rate of premature birth and stillbirth. However, there is no evidence linking smoking with heart problems in babies.

Will subsequent children have heart problems ?

In most families, abnormalities of the heart do not occur in siblings. In a few families, however, subsequent children may be affected. While it is inevitable that parents will be anxious about the health of their next baby, the risks are usually low. When one child has a congenital heart problem, the risk for the next pregnancy is usually between 2% and 4% (i.e. 1 in 50 to 1 in 25). It is often possible to diagnose a major heart abnormality on an ultrasound scan carried out at around four months or later in the pregnancy. Mothers who have had a previous child with a heart problem will naturally hope that any new baby will be healthy. If they wish to have a scan in subsequent pregnancies, they will need to be referred to one of the experts in this specialised field. Such scans will usually be carried out at one of the major obstetric units in Melbourne or at the Royal Children’s Hospital.

How is a heart condition diagnosed ?

About one third of affected babies develop symptoms in the early weeks of life. The abnormalities which are present in some babies lead to mixing of dark (blue) blood from the veins with the bright (red) blood from the lungs. The blood then flowing to the body and its organs is dark instead of being bright. This produces a bluish colour of the lips and skin (called cyanosis), hence the term ‘blue baby’.

In other children, even if blueness is not present, the heart may not be able to perform the extra work caused by the abnormality. Such children may develop symptoms, such as marked shortness of breath and difficulty with feeding. This is usually due to build up of fluid (congestion) in the lungs or other organs such as the liver. Doctors refer to this congestion as ‘heart failure’.

In at least half of the children with heart abnormalities, there are no symptoms and the disorder is recognised when the child has an illness, or during a routine examination. The condition is usually recognised by the presence of a heart murmur, heard with the doctor’s stethoscope while examining the heart. These murmurs result from turbulence in the flow of blood as the heart beats. Many heart abnormalities lead to greatly increased turbulence and hence produce quite loud murmurs. However, murmurs are not always due to heart defects and may have no significance. About 50% of children with normal hearts have faint heart murmurs. These ‘innocent murmurs’ tend to be more apparent during illnesses associated with fever, and this is when they are often detected.

If a heart defect is present, the nature of the problem and its severity must be assessed, and this will involve some tests. These are called non-invasive as nothing is introduced into the body during these tests. An X-ray and a recording of the electrical activity of the heart (ECG) are usually required. The most important test is an ultrasound scan of the heart (echocardiogram), which is similar to the scan which most mothers have during pregnancy. This test is not painful and involves no risk. Some children may need to be sedated with a mild medication so they can lie still to obtain the test results. With an echocardiogram, it is often possible to make a very precise diagnosis of the nature and severity of the heart problem. The test takes between 15 minutes and 1 hour to perform. Sometimes, especially with more complicated heart problems, the test may need to be repeated several times to obtain complete information.

If the baby has symptoms of heart failure in the early months of life, further investigations (e.g. cardiac catheterisation) may be required. The object of these investigations is to confirm the diagnosis and to obtain detailed information about the heart abnormality and its effects on the lung circulation. This information cannot be obtained by other means.

In many cases, especially where there is no evidence of strain on the heart, such tests may not be necessary or may be postponed until the child is older. They may often be carried out as part of the preparation for an operation.

What is meant by cardiac catheterisation and interventional procedures ?

The term ‘cardiac catheterisation’ refers to the passage of a fine tube (called a catheter) into the heart chambers through a vein, or an artery, usually from the top of the right leg just below the groin. By this means, blood samples and pressure measurements can be obtained from within the various chambers of the heart. This provides much information about the effects of the heart problem on the function of the heart and on the lung circulation. Usually, X-ray dye is injected to obtain pictures of the heart chambers and vessels (angiocardiography). These tests are only required when adequate information cannot be obtained by other methods (e.g. echocardiography), or when the cardiologist advises that the heart problem needs special treatment involving heart catheterisation (called an ‘interventional procedure’). Procedures of this latter type may be used to stretch open a narrow valve or blood vessel, using a catheter with an inflatable balloon. Alternatively, a tiny ‘spring coil’ may be inserted to block off an abnormal and unwanted blood vessel, or an expanding plug (usually referred to as a ‘device’) may be placed to close a hole such as an ASD or VSD.

A general anaesthetic will usually be given for these tests or procedures. The child will normally be admitted to hospital on the day of the test and discharged a few hours after it. Arrangements will be made to discuss the initial results of the test with the parents on the day of the procedure. The final results will often need to be discussed in conference (e.g. with the heart surgeons) before making decisions about further management, and so may not be available for several days.

The skin puncture, through which the catheter is inserted, does not usually need stitches, but there is often some bruising which will leave some soreness for a few days. Otherwise, there should be no ill effects after the procedure, though the anaesthetic may lead to nausea or vomiting for a few hours, and general tiredness for a day or two in some individuals.
