RESUMO
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.

A 53-year-old woman was developed congestive heart failure. She was diagnosed as having aortic coarctation, incompetent bicuspid aortic valve and an aberrant right subclavian artery by using echocardiography and enhanced computed tomography. Ankle brachial pressure index(ABI)in the right was 0.71 and 0.69 in the left. Blood pressure of the right arm was 60 mmHg lower than that of the left arm. To avoid perioperative adverse cardiac events due to a 2-staged operation, we performed ascending-descending aortic bypass and aortic valve replacement simultaneously through a median sternotomy. The heart was retracted cranially, and a vascular prosthesis was anastomosed to the descending aorta just above the diaphragm in an end-to-side manner. Then the graft was placed curvilinearly around the right atrium and was anastomosed to the ascending aorta. After the operation, the right and left ABI increased to 0.90 and 0.98 respectively. There was no pressure difference between the arms. The postoperative course was uneventful.
