Coronary Angiography Treatment India

Established as a diagnostic tool in 1927, angiography has become the backbone of interventional therapy over the last century. The term ‘angiography’ comes from the Greek words ἀνγεῖον angeion, "vessel", and γράφειν graphein which means "to write" or "to record”. In this procedure, the inner portion of blood vessels, veins, arteries, heart chambers and organs of the body are observed using X-rays.

Coronary angiography was introduced by Dr. Mason Sones in the early 1950’s. It is a semi-invasive diagnostic X-ray examination of the vessels and chambers of the heart and is used to detect any narrowed or clogged coronary arteries that prevent blood from reaching the heart muscle. Coronary angiography can only be performed by cardiologists, or doctors who specialize in this field.

During this procedure, a small area on the patient’s arm, groin, upper thigh, or neck is first cleaned and numbed with a local anesthetic and then a small opening is made in a blood vessel in this area. Then a thin hollow flexible tube, (called a catheter) is inserted into the blood vessel and observed as it travels into the heart. Once the catheter is in place, a special dye (iodine-based contrast medium) is injected into the catheter and X-rays are taken, which can help identify narrowing or blockage of heart and coronary arteries.

If your doctor has suggested that you undergo a coronary angiography, here are few things you should know. A coronary angiography usually takes about 30 to 40 minutes. Preparation before the procedure and post-procedure care may require some more time. After the procedure, the patient is taken to a recovery area for observation and monitoring. Heart rate and blood pressure are also checked at the site of recovery. The patient is asked to lie flat and restrict movement for several hours to avoid bleeding from the area in which the catheter was inserted. For a while the puncture site is likely to remain tender or sore and may be slightly bruised with a small bump.

No traces of radiation remain in the body after the X-ray examination, and in most cases the X-rays do not have any side effects. In some patients, formation of blood clots, bleeding, damage to blood vessels may be observed. Some patients may develop allergic reactions to the dye used in the procedure. However, in most patients, coronary angiography has no side effects or complications.

Coronary angiogram reveals the extent and severity of all coronary artery blockages and helps the doctor select the best suited treatment for the patient. When performed after a heart attack, it helps the doctor to understand the location of the blockage then decide whether coronary artery bypass surgery (CABG), coronary angioplasty, or medical therapy is required. After angiography, the doctor may realize that surgery is not required, and all you need to do is take medicines to lower your blood pressure and cholesterol, eat a healthy diet and stay fit.
