Aneurysm of the left sinus of Valsalva causing aortic, mitral regurgitation and myocardial ischemia.

An aneurysm of the left sinus of Valsalva producing aortic and mitral regurgitation with myocardial ischemia was treated successfully by reconstructing the left coronary sinus while preserving the aortic cusp combined with coronary artery bypass grafting. Aortic and mitral regurgitation occurred due to distortion of the left aortic cusp by a huge aneurysm that also compressed and obstructed the main trunk of the left coronary artery. The postoperative course was uneventful and follow-up showed aortic and mitral regurgitation to be absent and the coronary graft to be patent. Aortic valve-sparing surgery thus proved to be an appropriate procedure for this case.
