An 86-year-old lady with severe aortic stenosis and interventricular membranous septal aneurysm underwent transfemoral transcatheter aortic valve implantation (TAVI). A balloon-expandable valve was deployed after a difficult native valve crossing. Transesophageal echocardiography showed a rapidly accumulating pericardial effusion, with pericardial thrombus and subsequent cardiac tamponade. The angiographic views raised suspicion of aortic root perforation. Median sternotomy was performed because of sudden hemodynamic collapse.The report presents the uncommon association between severe aortic stenosis and interventricular membranous septal aneurysm in an octogenarian and discusses its impact on the development of a post-TAVI major complication.

“…An interventricular membranous septal aneurysm, though rare, can coexist with aortic valve stenosis. Patients with both these conditions have reportedly been treated with TAVR successfully 1,2 . However, in such patients, the aneurysm and its connection with the aortic root were present below the level of the aortic annulus; thus, the TAVR valves could seal a paravalvular leak at the annulus level in a standard implanted position.…”

An interventricular membranous septal aneurysm, though rare, can coexist with aortic valve stenosis. In this report, we present an unsuitable anatomy for transcatheter aortic valve replacement (TAVR) due to large interventricular membranous septal aneurysm. This case suggests that the feasibility of TAVR would depend on the location and size of the aneurysm and its relationship with the aortic root.

“…The coexistence of membranous ventricular septum aneurysm (MVSA) and aortic stenosis (AS) is extremely rare, 1 and its treatment is seldom reported. However, Hawa et al 2 reported the use of transcatheter aortic valve replacement (AVR) in a patient with AS and MVSA. Considering that MVSAs are located in the membranous septum right below the annulus, suturing a classical stented bioprosthetic valve may be unsafe.…”

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.
