Key result
Urgent MVR for post-MI papillary muscle rupture fails to prevent mortality due to postoperative complications.
Why the study?
Papillary muscle rupture is often underdiagnosed or diagnosed late due to its low incidence and nonspecific symptoms in acutely presenting, critically ill patients.
Population
A 74-year-old male with acute mitral regurgitation secondary to PMR following inferior wall infarction

Persistent high mortality despite urgent MVR in PMR post-inferior MI; leaves open optimal surgical selection and timing.
Case Report (n=1)
No
This case highlights the rapid hemodynamic collapse associated with acute papillary muscle rupture following delayed presentation of inferior MI, emphasizing the need for prompt diagnosis and intervention despite high mortality.
Sharma et al. (2026) conducted a case report in 74-year-old male with acute inferior ST-segment elevation myocardial infarction complicated by papillary muscle rupture and cardiogenic shock (n=1). Urgent surgical mitral valve replacement with papillary muscle excision was evaluated on Survival and hemodynamic stabilization after urgent mitral valve replacement surgery for papillary muscle rupture. Urgent surgical mitral valve replacement following acute papillary muscle rupture after inferior MI in a 74-year-old male did not prevent mortality due to postoperative complications and poor prognosis.
