First Experience Using a Nonfenestrated Cardioform Septal Occluder for Closure of Giant Mitral Paravalvular Leak

A variety of fenestrated vascular plugs have been used to seal paravalvular leaks with meaningful success; however, incomplete closure and refractory hemolysis remains a common problem. We describe the feasibility and rationale of their first experience using a nonfenestrated Cardioform Septal Occluder (Gore Medical, Flagstaff, Arizona) to treat a giant mitral paravalvular leak. (Level of Difficulty: Advanced.)
