Title: the left main complication of the bentall¿s procedure.A (b)(6) gentleman presented originally in 2009 for routine health assessment prior to competing in the (b)(6) marathon.Examination revealed a systolic murmur and an echocardiogram indicated moderate to severe aortic stenosis.In (b)(6) 2010, given the combination of moderate to severe aortic stenosis and a dilated ascending aorta, the patient underwent aortic root and ascending aorta replacement with a hemi arch replacement.During the procedure, the left main coronary artery was then re-implanted with prolene 5-0 suture material.Twelve months after surgery, the patient was presented with exertional dyspnea.The patient¿s ct coronary angiogram suggested a very tight ostial stenosis.He then underwent coronary artery bypass grafting with an lima to lad graft.Almost 2 years following the second operation the patient remains well.It was reported that the presumed mechanisms for ostial left main stenosis following the bentall¿s procedure included an inflammatory fibrous reaction to the suture material or tissue glue used during re-implantation of the coronary arteries, suture methods that result in kinking or stretching of the vessel, or a result of instrumentation of the coronary ostia during the induction of cardioplegia.It was concluded that the bentall¿s procedure is a well proven operation with excellent long-term results.It may, however, be complicated by proximal stenosis of the re-implanted coronary arteries.
