We present a case of a patient with preexisting mechanical mitral valve who developed a traumatic ventricular septal defect following a motor vehicle accident. Serial transthoracic echocardiography revealed the progressive nature of the defect. Surgical repair was delayed due to significant noncardiac comorbidities. The ventricular septal defect was found in an unusual location in the membranous portion of the interventricular septum. We discuss the possible etiologic mechanisms of injury as well as the importance of timely surgical repair.
我们报告了 1 例患者，该患者先前存在机械性二尖瓣，在机动车事故后出现创伤性室间隔缺损。连续经胸超声心动图显示了缺损的进行性特征。由于严重的非心脏合并症，手术修复被延迟。室间隔缺损位于间隔膜部的异常位置。我们讨论了损伤的可能病因机制以及及时手术修复的重要性。
