A 60-year-old male presented with sudden onset chest pain and pulmonary edema. The investigation confirmed torrential aortic regurgitation of a bicuspid valve. At surgery, a ruptured fibrous strand was identified which had been supporting the left-right cusp commissure with loss of attachment to the aortic wall. This case demonstrates that fibrous strands may be present as a supporting structure of the aortic valve, and rupture can be a rare cause of torrential aortic regurgitation, similar in pathogenesis to how it may be associated with acute severe mitral regurgitation and chordae tendineae rupture.
一位 60 岁男性突发胸痛和肺水肿。检查证实为二叶式主动脉瓣大量反流。手术时发现一条断裂的纤维束，该纤维束曾支撑着左右瓣叶的连合处，现已与主动脉壁失去连接。本病例表明纤维束可能作为主动脉瓣的支撑结构，其断裂可能是大量主动脉瓣反流的罕见原因，其发病机制类似于它如何与急性重度二尖瓣反流和腱索断裂相关。
