ABSTRACT

A substantial corpus of literature exists on the structure of the coronary arterial system, including di- agnostic and therapeutic options. However, there is a paucity of theoretical and practical information about the venous structure and drainage of the heart. The impact of valvular heart diseases on the haemodynamic, ischaemic and vascular systems of the heart has been recognised for many years, and significant advancements in treatment have been facilitated by recent medical developments. Howev- er, literature data on the relationship between valvular heart diseases and the coronary venous system remains inconclusive. Pulmonary artery stenosis, or stenosis affecting the size and pressure of the right atrium, may impair coronary venous flow. Coronary sinus dimensions have been observed to be increased in patients with ischaemic mitral regurgitation, suggesting a potential impact on coronary venous flow. Furthermore, advanced aortic valve diseases have been observed to induce congestion within the coronary venous system by increasing left ventricular pressure. It has been found that tricus- pid regurgitation developing without any other cardiac pathology is not associated with coronary sinus dilatation. However, tricuspid stenosis has been observed to impede coronary venous flow by affecting right atrial dimensions and pressure.
