An isolated quadricuspid aortic
valve is an extremely rare congenital anomaly and there have
been few surgical case reports published. A 47-year-old man with
untreated diabetes mellitus was admitted to our institution because
of fever and dyspnea. Transesophageal echocardiography showed
severe aortic valve regurgitation and a quadricuspid valve with
vegetations. Blood culture revealed Streptococcus agalactiae.
Despite administration of antibiotics and treatment of his heart
failure, the infection and heart failure were not controlled.
Therefore, we performed aortic valve replacement in the presence
of active infective endocarditis. The aortic valve had 2 equal-sized
larger cusps and 2 equal-sized smaller cusps. There were vegetations
on each cusp and an annular abscess was detected. The resection
site of the abscess was reinforced with an autologous pericardial
patch, and the aortic valve was replaced using a 21-mm SJM valve.
His postoperative course was uneventful and he was discharged
after recovery.
