Sinus of Valsalva aneurysms involving both coronary ostia.

Sinus of Valsalva aneurysms are a rare cause of angina or myocardial infarction. We describe a patient with unstable angina and massive unruptured aneurysms of both coronary sinuses causing severe distortion of both coronary ostia, to our knowledge not previously reported. This unusual patient underwent aortic valve replacement, ascending aortic repair, and coronary artery bypass. At 11-year follow-up, she had developed severe mitral stenosis and prosthetic aortic valve stenosis. Review of the literature reveals 30 reported cases of Sinus of Valsalva aneurysm complicated by coronary insufficiency or infarction, involving either the left (20 cases) or the right coronary sinus (10 cases). We emphasize the poor outcome of these patients, especially if treated conservatively.
