Dor Operation - Endoventricular Circular Patch Plasty

Dor procedure or the Endoventricular Circular Patch Plasty (EVCCP), is an operation, introduced by Vincent Dor, in 1985. The procedure itself is a viable method of restoring a dilated left ventricle to its normal eliptical geometry. The Dor procedure, which uses a circular suture and a Dacron patch to correct LV aneurysms and exclude scarred parts of the septum and ventricular wall, would prove to be the best option amongst the other methods of ventricular remodeling. EVCPP is a relatively easy procedure that covers all aspects of successful heart restoration—restores ventricular shape, increases ejection fraction, decreases the left ventricular end systolic volume index (LVESVI), and allows for complete coronary revascularization. The following video demonstrates two cases of the endoventricular circular patch plasty of the left ventricle (Dor operation) during the large postinfarction akinetic aneurysms.
