متن کاملAortic valve leaflet perforation after mitral valve repair.
A 32-year-old patient with symptomatic severe aortic regurge, 6 weeks after mitral valve repair, was admitted for aortic valve surgery. No preoperative clinical data consistent with infective endocarditis could be detected. Preoperative transthoracic echocardiography showed aortic leaflet perforation affecting non coronary cusp. During operation, leaflet perforation was detected and closed comp...
