HEART TESTS : Heart & Blood Vessel Procedures


An Angiogram is an X-ray picture of the inside of blood vessels. A long slender tube called a catheter is inserted into an artery. The catheter is threaded through the artery until its tip reaches the segment of vessel to be examined.

These vessels can be those of the heart (coronary angiogram) or other parts of the body. This reveals any narrowing or blockages of the arteries and other abnormalities.

Peripheral and Percutaneous Coronary Intervention (PCI)

This is a non-surgical method performed to open narrowed or blocked arteries. It is performed by inserting a catheter through the skin into an artery.

At the leading tip of this catheter, several different devices such as a balloon, stent, or cutting device can be deployed to open up the narrow or blocked artery. Blockages or narrowing of coronary arteries and those of the legs, are commonly treated in this manner.

Loop Recorder Insertion

In people who have infrequently occurring heart rhythm disturbances, a small device can be implanted under the skin on the chest which records the ECG like a Holter monitor.

Pacemaker Insertion

A Pacemaker is a battery-operated device that is implanted under the skin with wires that make contact inside the heart. It sends electrical pulses that keep the heart beating regularly.

ICD Insertion

An Internal Cardiac Defibrillator (ICD) is a special pacemaker with 1 or 2 leads. These leads are used to monitor the heart rhythm and when it becomes very erratic or too rapid, the ICD delivers a shock to the heart to put it back to normal.

CRT/D Insertion

Cardiac Resynchronization Therapy (CRT) is insertion of a special pacemaker that has 3 wires leading into the heart instead of the usual 1 or 2.

It is used in patients with heart failure who have heart muscle that contracts out of sync. It synchronises the muscle contraction and makes the heart work more efficiently. A CRTD is a CRT pacemaker with a defibrillator.

Right and Left Heart Catheterization

In this procedure, a catheter is put into a blood vessel and advanced to various chambers of the heart to measure pressures and occasionally, oxygen content of the blood.

Venous Ablation

In this procedure, a laser or radio-ablation catheter is used to shut down large veins in the legs that are responsible for causing varicose veins. This cures pain swelling and ulceration caused by the varicose veins.
