Abstract:
We report a case of aneurysm located at the right sinus of Valsalva with mild aortic regurgitation (AR). The patient was a 55-year-old man with hypertension. When he consulted a local doctor complaining of back pain, aneurysm of right sinus of Valsalva was unexpectedly diagnosed by detailed examinations. He was transferred to our hospital for surgery. An echocardiogram showed mild aortic regurgitation and enlargement of the right sinus of Valsalva. Computed tomography demonstrated an unruptured and extracardiac aneurysm of the right sinus of Valsalva (diameter, 45 mm) and a right coronary artery (RCA) that originated from just above the ostium of the aneurysm. He underwent a partial aortic root remodeling procedure with trimmed Hemashield graft and the RCA was anastomosed to the Hemashield graft by the Carrel patch technique. The postoperative course was uneventful, and he was discharged on the 12th postoperative day. Postoperative angiography revealed that aneurysm of the right sinus of Valsalva was not enhanced and the RCA was patent. This procedure preserve the patient's own aortic valve and normal sinus of Valsalva and enabled him to have more physiologic hemodynamics than patch closure, although progression of the AR requires careful follow-up.
