Aortic valve endocarditis can lead to secondary involvement of aorto-mitral curtain and the adjacent anterior mitral leaflet (AML). The secondary damage to AML is often caused by the infected jet of aortic regurgitation hitting the ventricular surface of the mitral leaflet, or by the pronounced bacterial vegetation that prolapses from the aortic valve into the left ventricular outflow tract. This is called 'kissing lesion'. We describe a patient with infective endocarditis of the aortic valve causing perforation of both noncoronary cusp of aortic valve and the AML, which is rare.
主动脉瓣心内膜炎可导致主动脉瓣-二尖瓣瓣环及毗邻的二尖瓣前叶(AML)的继发性受累。AML 的继发性损害通常是由感染性主动脉瓣反流的喷射流冲击二尖瓣叶的心室面引起的,或者是由从主动脉瓣脱垂入左心室流出道的明显细菌赘生物引起的。这被称为“亲吻性病灶”。我们描述了一例主动脉瓣感染性心内膜炎导致非冠状动脉瓣及 AML 穿孔的患者,这种情况较为罕见。
