BACKGROUND: Percutaneous closure of aortic and ventricular pseudoaneurysms (PSA) has only been reported on a case report and series basis. In previous case reports, percutaneous closure has been performed successfully in patients of prohibitive surgical risk. This case series aims to show feasibility of percutaneous closure of aortic and ventricular pseudoaneurysm secondary to perivalvular leak (PVL) in a small patient population and the utility of multimodality imaging as an integral tool in procedural planning. This is the largest complex case series to date describing the feasibility and success rate of complex PSA closure, with a follow-up period of up to 4 years.

MATERIAL AND METHODS: We performed institutional review and systemic literature review to identify all paravalvular leak cases with associated pseudoaneurysm formation for which a closure procedure was performed. Ten patients were identified. Pooled analysis for cases from institutional review (n = 10) and systemic literature review (n = 39) was performed. The success rate was 100 %. At 30-days, the mortality was 0 %.

CONCLUSION: In paravalvular leak patients with subsequent pseudoaneurysm formation, exhaustive imaging evaluation is required for closure. However, it can be achievable with favorable rates of success.
