title: Selective retrograde coronary venous perfusion.
abstract: The theoretical concept of delivering oxygenated blood to an ischemic myocardium by way of the coronary venous system antedated by many decades the present widespread utilization of coronary artery bypass grafting. Diffuse arterial atherosclerosis has limited the effectiveness of coronary artery bypass grafting in about 15% of patients seen with significant angina pectoris. Consequently, there has been renewed interest in selectively reversing the flow in certain coronary veins through coronary venous bypass grafts. This collective review details the physiology and anatomy of the coronary venous system. It then discusses the early attempts to globally retroperfuse the entire coronary venous system through the coronary sinus. Finally, the current experimental and clinical attempts to selectively retroperfuse just one region of the coronary venous system are presented and reviewed.
