Pericardial Patch Closure Combined with Coronary Artery Bypass Grafting in a Case of Isolated Extracardiac Unruptured Left Sinus of Valsalva Aneurysm with Stenosis of the Main Trunk of the Left Coronary Artery / 日本心臓血管外科学会雑誌

A 76-year-old woman was admitted to our hospital because of sudden onset of chest pain and dyspnea. Echocardiography, chest CT, and cardiac catheterization revealed an isolated extracardiac unruptured left sinus of Valsalva aneurysm, with stenosis of the main trunk of the left coronary artery. Neither aortic regurgitation nor aortic annular dilatation was recognized. As an infection associated sinus of Valsalva aneurysm could not be ruled out, we performed patch closure using autologous pericardium and coronary artery bypass grafting to the left coronary system. The postoperative course was uneventful. One year after the operation, CT revealed that aneurysm of the left sinus of Valsalva had disappeared and that the grafts were patent.
