Understanding Coronary Artery Bypass And Internal Mammary Graft

A coronary artery bypass surgery becomes necessary when the coronary artery gets blocked due to plaque formation. This disease is called coronary artery disease or CAD. A plaque is formed because of the deposit of fatty substances like cholesterol in the inner walls of the artery.

Coronary Sinus Function

In the heart, a coronary sinus is an aggregation of veins that have been joined together to form a large blood vessel. It collects blood from the myocardium or the wall of the heart. It is present in the right atrium and is sheltered by the coronary valve. The coronary valve is a part of the lining membrane of the auricle, which is semicircular in shape. The coronary sinus has an opening called coronary sinus orifice. It is also known as the ostium of the coronary sinus. It is protected by the Thesbian valve.
