Transapical Mitral Valve Implantation After Closure of Posterior Mitral Annulus Cavity With a Nitinol Occluder
Key result
Cavity closure using a Nitinol occluder device and transcatheter mitral valve implantation successfully managed severe postendocarditis mitral regurgitation in a high-risk surgical patient.
Why the study?
Mitral valve infective endocarditis involves a mitral annular abscess in approximately 15% of cases, for which surgery is standard, leaving an open question for nonsurgical candidates.
Population
One 80-year-old comorbid man with eradicated infective endocarditis and severe mitral regurgitation not eligible for surgery

Population
An 80-year-old man with eradicated infective endocarditis, severe paravalvular and transvalvular mitral regurgitation, and prohibitively high surgical risk.
I
Intervention
Cavity closure using a Nitinol occluder device and transcatheter mitral valve implantation.

Maznyczka et al. (2025) conducted a case report in Eradicated infective endocarditis with severe paravalvular and transvalvular mitral regurgitation (n=1). Cavity closure using a Nitinol occluder device and transcatheter mitral valve implantation was evaluated on Successful management. Cavity closure using a Nitinol occluder device and transcatheter mitral valve implantation successfully managed severe postendocarditis mitral regurgitation in a high-risk surgical patient.
