Why the study?
Does retrograde coronary venous perfusion provide effective myocardial perfusion in a patient with an aorto-coronary venous anastomosis?
Does retrograde coronary venous perfusion provide effective myocardial perfusion in a patient with an aorto-coronary venous anastomosis?
An inadvertently created aorto-coronary venous anastomosis showed no angiographic evidence of myocardial perfusion, providing evidence against the clinical effectiveness of retrograde coronary venous perfusion.
No perfusion via inadvertent aorto-coronary venous anastomosis; leaves open retrograde venous perfusion efficacy and warrants prospective study.
Arterilization of the coronary venous system has been suggested as a means of myocardial perfusion. We recently studied a patient with a saphenous vein aorto=coronary venous bypass graft created inadvertently during surgery intended to bypass the anterior descending artery. We selectively injected onctrast into this graft during balloon occlusion of the coronary sinus both before and after sublingual nitroglycerin. No arterial visualization was demonstrated from the vein and no evidence to suggest perfusion of the myocardium was found.
