[Aortic regurgitation caused by prolapsed noncoronary cusp associated with dissecting aortic aneurysm treated by placing a prosthetic graft onto the anulus: report of a case].
A 70-year-old man with severe aortic regurgitation (AR) associated with dissecting aortic aneurysm underwent a radical operation. AR was thought to be due to dilated sinotubular junction and prolapsed noncoronary cusp caused by dissecting flap extended into the sinus of Valsalva. At operation, the noncoronary cusp was slightly prolapsed into the left ventricle, but all cusps were seemed to be thin and pliable. An isolated "tongue shaped" graft was placed onto the anulus of the noncoronary cusp, and a 26 mm Woven Dacron graft was used to replace the ascending aorta. Postoperative angiogram showed mild AR and improved left ventricular (LV) function. This procedure was effective to repair AR caused by prolapsed noncoronary cusp without elongation or thickening of the valve.
