The aortic chordae tendineae strands are suggested to be embryonic remnants of the cusp formation process. We herein describe a 70-year-old male who was admitted to our hospital for shortness of breath and chest tightness. During echocardiographic examination, severe aortic regurgitation with a ruptured fibrous strand was detected. Moreover, another fibrous strand was found by three-dimensional transesophageal echocardiography (TEE). To our knowledge, this is the first literature review of aortic chordae tendineae strands, including diagnosis, management, and mechanisms of aortic regurgitation due to such informal strands.
主动脉瓣腱索条索被认为是瓣膜形成过程中的胚胎残留物。本研究描述了一名 70 岁男性，因呼吸急促和胸闷入院。超声心动图检查发现严重主动脉瓣反流伴纤维条索撕裂。此外，三维经食管超声心动图（TEE）还发现了另一条纤维条索。据我们所知，这是首次对主动脉瓣腱索条索进行文献回顾，包括此类非正式条索导致主动脉瓣反流的诊断、处理和机制。
