VD05 BENTALL OPERATION IN BICUSPID VALVE AND ANOMALOUS LEFT CIRCUMFLEX CORONARY ARTERY: ANATOMICAL AND TECHNICAL IMPLICATIONS

Abstract

Abstract Bicuspid aortic valve (BAV) is often associated with coronary abnormalities. The finding of BAV associated with an anomalous circumflex coronary artery (ACCA) originating from the right Valsalva sinus (VS) and surrounding the non-coronary VS is however a rather rare occurrence. We report a case of successful Bentall operation with a composite button technique in a 56-year-old man with aortic root dilatation, BAV insufficiency and coexisting ACCA. In this case a 25 SJM composite graft was implanted in supraannular fashion rather than intraannular to avoid: 1) ACCA injury or obstruction of the proximal course near the annulus by suture ligation, 2) compression by prosthetic ring, 3) distortion of ACCA during ostia reimplantation. We demonstrated that attention to the anatomic relationship of ACCA to the aorta is crucial and prosthesis supraannular implantation technique allows a safe aortic root replacement.
