Repair for mitral valve aneurysm using autologous pericardium: a case of our experience.

Mitral Valve Aneurysm (MVA) is rarely reported and occurs most in association with infective endocarditis of the aortic valve. In our case, the 46-yr-old Chinese man was referred to our hospital with dyspnea and orthopnea. Transesophageal echocardiography during operation revealed a localized, thin-walled saccular structure in the anterior leaflet that bulged into the left atrium, and severe mitral and aortic regurgitation. Aortic valve was replaced with mechanical prostheses and mitral valve was repaired with autologous pericardium. Transesophageal echocardiography during operation and transthoracic echocardiography 3 months later showed mild regurgitation.
