Figure 2

Position of proximal coronary artery segment to the aorta before and after Bentall surgery. Figure A shows the normal anatomy of the native coronary arteries arising from the coronary sinuses of the native aneurysmal ascending aorta before surgery. Figure B shows the mobilized native coronary arteries and the ‘button’ or cuff of native aortic tissue being re-implanted end-to-side to the prosthetic aortic graft post Bentall surgery. The ‘new’ coronary ostia-aorta anastomotic site is now positioned superiorly compared to the original anatomy.
