QUADRICUSPID AORTIC VALVE PERFORATION RESULTING FROM BACTERIAL ENDOCARDITIS : 2-D Echo- and Angiographic Diagnosis and its Surgical Treatment

Abstract

A 75-year-old man with quadricuspid aortic valve regurgitation affected by bacterial endocarditis is reported. The aortic valve consisted of 4 equalsized cusps (type a) and supernumerary cusp located between the right and noncoronary cusps. A right coronary ostium was close to the accessory commissure, but there was no displacement. A few small fenestrations were found at the 4 commissures and a large perforation resulting from endocarditis was observed in the noncoronary cusp. 2-D echocardiogram and angiogram suggested these findings, and they were confirmed at surgery. Successful aortic valve replacement was achieved.
