We report the case of acquired left ventricle (LV) to right atrial (RA) communication through an aneurysm of the atrioventricular septum caused by infectious endocarditis. A severe aortic valve regurgitation and destruction of the aortic valve was detected by echocardiography. Transesophageal echocardiography revealed a flail aortic valve with vegetation and abnormal shunt flow from the LV to RA with ruptured aneurysm of the membranous septum. An abscess cavity of the aortic ring was introduced. Because of worsening congestive heart failure, the patient underwent emergency aortic valve replacement and patch closure of the communication of the membranous septum. The patient's postoperative course was uneventful.
我们报告了一例因感染性心内膜炎导致房室间隔动脉瘤形成，进而出现后天性左心室（LV）至右心房（RA）交通的病例。经超声心动图检查发现严重的主动脉瓣反流及主动脉瓣破坏。经食管超声心动图显示主动脉瓣连枷样病变伴赘生物，以及膜周部间隔动脉瘤破裂导致的从左心室至右心房的异常分流。发现主动脉环有脓肿腔。由于充血性心力衰竭加重，患者接受了急诊主动脉瓣置换术及膜周部间隔交通口的补片修补术。患者术后恢复顺利。
