Key result
Surgical repair of a rare post-MI ventricular triple rupture proves fatal at 32 days.
Why the study?
Cardiac rupture is a life-threatening complication of acute myocardial infarction, and combining free-wall rupture, ventricular septal perforation, and papillary muscle rupture is extremely rare.

This report describes the first known case of ventricular triple rupture following acute myocardial infarction, highlighting a rare and highly fatal mechanical complication.
Post-MI ventricular triple rupture carries high mortality despite surgery; extends reported cases but leaves optimal management open.
Cardiac rupture, such as ventricular free-wall rupture, ventricular septal perforation, and papillary muscle rupture, is a life-threatening complication of acute myocardial infarction. Herein, we report a very rare case of combining these three types of ventricular rupture. A 71-year-old woman underwent mitral valve replacement and left ventricular free-wall rupture repair after an acute myocardial infarction. She was transferred to our hospital under mechanical support by venoarterial extracorporeal membrane oxygenation and intra-aortic balloon pump due to circulatory collapse. Transthoracic echocardiography revealed a left-to-right shunt caused by ventricular septal perforation. The patient underwent endoventricular patch plasty for septal defect closure. Unfortunately, a prolonged postoperative course led to the development of multi-organ failure followed by fatal outcome on day 32 postoperatively. To our best knowledge, this is the first reported case of ventricular triple rupture associated with acute myocardial infarction.

Kaneko et al. (2023) conducted a case report in Ventricular triple rupture after acute myocardial infarction (n=1). Surgical repair (mitral valve replacement, free-wall rupture repair, endoventricular patch plasty) and mechanical support was evaluated. Surgical repair of a rare ventricular triple rupture (free-wall, septal, and papillary muscle) after acute myocardial infarction in a 71-year-old woman resulted in a fatal outcome on day 32.
