Such a complication has been attributed to undue tension developing at the suture line of the side-to-side coronary anastomosis in large aneurysms, or by blood accumulation inside the aortic wrap8.
The new generation of Dacron grafts and the various technical modifications in Bentall procedure that were aimed to reduce tension on coronary anastomoses buttons have effectively prevented bleeding from the anastomoses between the graft and coronary anastomosis.6,7 Despite all these, early mortality and non-cardiac morbidity rates are still higher than for other cardiac surgical procedures, and these rates correlate closely with excessive bleeding during operation.8-10 Bleeding is still a devastating complication after root replacement surgery.7
Off-pump coronary artery bypass (OPCABG) is a technique of performing coronary anastomosis on a beating heart without instituting cardio pulmonary bypass.
