PROCEDURES I CORONARY ANGIOGRAM
A coronary angiogram utilises x-ray imaging to view the heart’s blood vessels in detail. The test is designed to check for obstructions in the coronary arteries, limiting blood flow to the heart.
As contrast dye moves through the coronary arteries via a fine plastic tube (catheter) while Dr Hassen examines how the blood flows through the arteries on an x-ray. Before performing the procedure, he may conduct a CT or MRI scan to check for abnormalities affecting the functioning of the heart muscle. Then, an angiogram of the heart is done to diagnose distressing symptoms linked to heart failure and to help formulate a treatment plan that may be implemented ahead of time.
How do you perform the procedure?
A mild sedative may be administered to keep you calm but awake during the procedure. Dr Hassen sterilises a point in the groin or arm where he will insert a sheath in the artery. Afterwards, he places a catheter through the opening, which he guides through to the artery leading up to the heart. Dr Hassen moves and threads the catheter through the coronary arteries. A special dye injected through the catheter highlights the arteries on an x-ray. Fortunately, Dr Hassen supervises the entire process on his x-ray screen. He watches as the dye moves through the blood vessels. The speed at which the contrast liquid flows determines the severity of the obstruction. At the same time, Dr Hassen can carry out interventional surgical procedures such as stent placement and balloon angioplasty to widen a constricted artery. When he threads the catheter through, you should not feel any pain or feel it moving through your blood vessels.
After a coronary angiogram, Dr Hassen places pressure on the incision site and removes the catheter gently to prevent bleeding. Once he removes the catheter, you will be asked to lie on your back to prevent further bleeding.
