Angiography is a medical imaging technique used to visualize the inside, of blood vessels and organs of the body, with particular interest in the arteries veins heart chambers. This is traditionally done by injecting a contrast agent(dye) into the blood vessel and imaging using X-ray based techniques such asfluoroscopy.

A long, thin, flexible tube called a catheter is used to administer the x-ray contrast agent at the origin of the arteries supplying the heart. The catheter is threaded into an artery in the forearm or the groin, and the tip is advanced through the arterial system into the origin of the major coronary arteries one at a time. X-ray images of the dye distribution within the blood flowing within the coronary arteries allows visualization of the size of the artery openings. Presence or absence of blockages in the arteries be clearly determined.

Angioplasty is a procedure that uses a flexible plastic catheter with a balloon at the end to dilate narrowed arteries in the heart. It is the technique of mechanically widening a narrowed or obstructed blood vessel. An empty and collapsed balloon on a guide wire, known as a balloon catheter, is passed into the narrowed locations and then inflated to a fixed size using water pressures some 75 to 500 times normal blood pressure (6 to 20 atmospheres). The balloon crushes the fatty deposits, opening up the blood vessel for improved flow, and the balloon is then deflated and withdrawn. The procedure often includes placement of a metal stent to hold the artery open. In this way, angioplasty helps to restore blood flow to the heart muscle.

Why do I need angioplasty ?

Chest pain that originates from the heart muscle due to lack of blood supply is called angina pectoris. Angina is a signal that the heart muscle is not getting sufficient blood flow, specifically sufficient oxygen. Lack of oxygen is termed ischemia. Blood flow is most often reduced by coronary artery disease (CAD), which causes a narrowing of the arteries that carry blood to the heart muscle Narrowing in the coronary arteries occurs as a result of calcium and fatty deposits, called plaques.

A person with narrowed arteries may develop angina during activity, exercise, or any other physical or mental stress that increases the heart’s demand for blood.
The term acute coronary syndrome refers to people with unstable angina or a heart attack; these conditions require immediate evaluation in a hospital. In severe cases, heart attack can lead to heart failure or sudden cardiac death.
