Membranous ventricular septum aneurysm (MVSA) is extremely rare, especially when coexisting with aortic stenosis (AS), and reports regarding the available treatment for MVSA with AS are limited. Aortic valve replacement (AVR) can be challenging because of anatomical reasons. In this case report, a patient with MVSA and severe AS was treated with AVR with the sutureless Perceval bioprosthesis. After implantation, no paravalvular leakage was detected in echocardiography, and no other postoperative complications were observed. Postoperative electrocardiography-gated computed tomography revealed no contrast enhancement for MVSA. The MVSA was closed by the Perceval bioprosthetic valve. Thus, patients with simultaneous MVSA and AS may be effectively treated with AVR using a Perceval bioprosthesis.
膜性室间隔瘤（MVSA）极为罕见，尤其是与主动脉瓣狭窄（AS）并存时，关于MVSA合并AS的可用治疗方法的报道有限。由于解剖学原因，主动脉瓣置换术（AVR）可能具有挑战性。在本病例报告中，一名患有MVSA和严重AS的患者接受了使用无缝合Perceval生物假体的AVR治疗。植入后，超声心动图未检测到瓣周漏，也未观察到其他术后并发症。术后心电图门控计算机断层扫描显示MVSA无对比增强。MVSA被Perceval生物人工瓣膜封闭。因此，同时患有MVSA和AS的患者使用Perceval生物假体进行AVR可能得到有效治疗。
