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.
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.
Papillary muscle rupture (PMR) is often underdiagnosed or diagnosed late due to its low incidence and nonspecific symptoms in acutely presenting, critically ill patients. This report presents a case of a 74-year-old male who developed acute mitral regurgitation secondary to PMR in the context of an initially conservatively managed inferior wall infarction following recent spine surgery. The discussion highlights the most appropriate diagnostic approach for critically ill patients presenting with acute hypoxic respiratory failure in the cardiac ICU. It also examines optimal management strategies for PMR in the setting of cardiogenic shock and pulmonary edema, emphasizing the importance of timely recognition and targeted intervention.
Sharma et al. (Thu,) 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.
