The Cardiac Catheterisation Laboratory at Regency Specialist Hospital is equipped to provide a comprehensive range of cardiac care treatments in a comfortable and cosy environment. Using advanced cardiac imaging technology such as 64-slice CT scanner and echoardiogram, quick and accurate diagnoses of heart diseases can be achieved.

Our team of dedicated expert cardiologists, radiologists, specialty-trained nurses, as well as medical and radiology technologists perform diagnostic and coronary, peripheral and congenital interventional procedures for patients with cardiovascular diseases.


What is cardiac catheterisation?

Cardiac catheterisation is a procedure used to diagnose a variety of disorders of the heart such as valve abnormalities or coronary artery disease.

  • The cardiac catheterisation procedure is usually performed in a Cardiac Catheterisation Laboratory by a trained cardiologist to evaluate cardiac valvular disease, coronary artery disease, congenital heart abnormalities or disease of the aorta. It may also be used to determine the need for cardiac surgery.

    During cardiac catheterisation, other tests may be done and these include tests that:

    • Measure blood pressure in the heart chambers
    • Measure the amount of blood the heart pumps
    • Measure blood oxygen saturation level in the heart chambers
    • Evaluate heart muscle function

    Coronary Angiography or Coronary Arteriography is the most common cardiac catheterisation procedure performed in the cardiac catheterisation laboratory. This procedure which involves the injection of special contrast media (dye) into the coronary artery can show whether you have coronary artery disease.

  • Cardiac catheterisation may also be used to treat certain heart problems without having the patient undergoing major cardiac surgery. Therapeutic catheterisation may be used to restore flow to obstructed arteries by use of a balloon, stents, or grafts. Catheterisation may also be used to open stenotic (narrow) heart valves and to repair congenital defects.Angioplasty opens clogged arteries. It does this by compressing plaque against the artery wall. A catheter with a small balloon at its tip is moved to where the artery is clogged. The balloon is inflated and deflated a few times. This compresses the plaque, opens the artery and increases blood flow. Sometime, metallic stents may be placed permanently inside the clogged arteries to help keep it open.

    Other treatments for coronary artery disease may be done using cardiac catheterisation:

    • Atherectomy removes plaque from artery walls using a special catheter.
    • Medications can be delivered through the catheter to dissolve a blood clot in an artery.

Who needs to undergo cardiac catheterisation?

Your doctor may recommend this procedure if you are experiencing:

  • Chest pain
  • Shortness of breath, dizziness and/or fatigue

If you have signs of heart disease, this procedure helps the doctor identify the precise problem by revealing areas that have been narrowed or blocked by the fatty build-up of plague. Early detection and treatment can help you lower the risk of suffering a heart attack or stroke.


How is the procedure performed?

A long, thin, flexible tube called a catheter is inserted into a blood vessel in your arm or groin and gradually threaded into your heart. A special dye that shows up in X-rays may be injected through the catheter to help the doctor pinpoint the severity of the blockage.

The cardiologist will use special imaging equipment to view the catheter as it is threaded towards the heart. Once inside the heart, high resolution x-ray pictures are taken to provide accurate and prompt diagnosis and treatment of any heart problems, if needed.


What should you expect?

Before having cardiac catheterisation:

  • Inform your doctor about your current medication and allergies
  • Fast after midnight the day before the procedure
  • Arrange for transportation home as it may not be safe for you to drive after the procedure

A cardiac catheterisation takes at least an hour, after which you will remain lying down for 2 to 12 hours.


How safe is the procedure?

Generally, cardiac catheterisation is safe. Most of the side effects are minor such as temporary bruising of the area where the catheter had been inserted. You should discuss the risks and benefits thoroughly with your doctor before having the procedure.
