RADIOGRAPHIC STUDY OF RIGHT CORONARY ARTERY MORPHOLOGY

Abstract

Coronary angiography is the radiographic visualisation of the coronary vessels after the injection of a radiopaque contrast media. The radiographic images are recorded for the future review with 35mm cine film or digital recording. Percutaneous or cut down techniques, usually from the femoral or brachial artery, are used for the insertion of special intravascular catheters. Coronary angiography requires selective cannulation of the ostium of the left and right coronary arteries to obtain optimal selective contrast injection and imaging. The anatomy of coronary artery varies and several nomenclatures have been used to describe the anatomy and extent of disease. Currently, the most common one is that used in Coronary Artery Surgery Study (CASS), recently modified by the Bypass Angioplasty Revascularisation Investigation (BARI). In this tree the coronary nomenclature is divided into 29 segments with the ability to account for anatomic variations. In the present era people are opting for coronary angioplasty and coronary artery Bypass surgery almost on the counter in countries rich and poor. Knowledge of variations in the angiographic anatomy of coronary artery is vital in during interpretation of coronary angiography films, and managing congenital and acquired paediatric and adult heart diseases
