Atresia of the coronary sinus ostium: surgical implications
International Journal of Cardiology
|November 17, 2006
Abstract:
We report a neonatal case of atresia of the coronary sinus ostium draining into a persistent left superior caval vein, associated with aortic arch hypoplasia, ventricular septal defect and mitro-aortic discontinuity. In this setting, left superior caval vein receives the coronary flow, which is directed into the innominate vein and the right atrium. It is mandatory to perform a precise anatomical definition of this unusual cardiac malformation, before repair of associated cardiac defects. Indeed, the interruption of coronary venous drainage could potentially lead to myocardial ischemia and necrosis.

01:21Coronary Circulation
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

01:26Mitral Stenosis III: Medical Management
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
01:22Mitral Stenosis I: Introduction
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
