ABSTRACT
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.
ABSTRACT
Sinus of Valsalva aneurysm is a rare cardiac disorder, and reports of its origin among in the left sinus are scarce. This report describes a 38-year-old man with an isolated extracardiac unruptured aneurysm of the left sinus of Valsalva. The patient presented with chest pain due to compression of the main trunk of the left coronary artery by the aneurysm. The aneurysm was resected, and the aortic root was reconstructed using the Bentall procedure. Concomitantly, coronary artery bypass grafting (LITA-LAD) was added. Postoperative native coronary flow was fully restored, and his anginal symptoms disappeared despite occlusion of the additional LITA-LAD anastomosis. This type of case would be considered to not require concomitant CABG, since the cause of the coronary artery stricture was compression by an aneurysm in the left sinus of Valsalva.
