A 75-year-old man with quadricuspid aortic valve regurgitation affected by bacterial endocarditis is reported. The aortic valve consisted of 4 equal-sized cusps (type a) and a 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.
报道了一名75岁患有四叶式主动脉瓣反流并感染细菌性心内膜炎的男性患者。主动脉瓣由4个大小相等的瓣叶（a型）和一个位于右冠瓣与无冠瓣之间的多余瓣叶组成。右冠状动脉开口靠近副连合，但无移位。在4个连合处发现了一些小的开窗，在无冠瓣处观察到因心内膜炎导致的一个大穿孔。二维超声心动图和血管造影显示了这些发现，并在手术中得到证实。成功实施了主动脉瓣置换术。
