A 66-year-old man was admitted to this institution in February 1995 for evaluation of heart failure that occurred after he received a blood transfusion. A loud to-and-fro murmur was audible along the left sternal border. Hematocrit was 21.6%, CRP was elevated, and β-hemolytic streptococci was isolated in the blood culture. Transthoracic and transesophageal echocardiography showed aortic regurgitation and four cusps of equal size on the aortic valve with vegetation and fenestrations in the center of the right and noncoronary cusps, and these findings were visually confirmed on surgery. This is the first reported case of quadricuspid aortic valve associated with infective endocarditis that was diagnosed by echocardiography before surgery. Thirty-two other cases of quadricuspid aortic valve reported in Japan are also reviewed here.
