Key result
Surgical excision resolves late prosthetic mitral valve dysfunction caused by spontaneous papillary muscle rupture.
Why the study?
Prosthetic valve dysfunction due to entrapment of the subvalvular apparatus is a rare and poorly understood delayed postoperative complication.
Population
72-year-old woman with mechanical mitral valve prosthesis and rheumatic heart disease

Spontaneous papillary muscle rupture is a rare cause of late mechanical mitral valve dysfunction that can be diagnosed with TEE and successfully treated with surgical excision.
Pericàs et al. (2025) conducted a case report in Intermittent mitral prosthetic dysfunction (n=1). Surgical excision of ruptured chordae tendineae and residual papillary muscle was evaluated on Correction of prosthetic dysfunction. Surgical excision of the ruptured chordae tendineae and residual papillary muscle successfully resolved a rare case of late prosthetic mitral valve dysfunction caused by spontaneous papillary muscle rupture.
