Types of Post Myocardial Infarction (MI) Rupture

The following are the types of post MI rupture:

  • Left ventricular free wall rupture 1, 2, 3
  • Ventricular septal rupture 1, 4, 3
  • Papillary muscle rupture 1, 3

Characteristics of Each Type

  • Left ventricular free wall rupture: typically occurs within the first week after the infarct, with higher incidence in patients with anterior myocardial infarction 2
  • Ventricular septal rupture: associated with a high mortality rate if not treated, early surgical repair is recommended regardless of haemodynamic status 4
  • Papillary muscle rupture: accounts for a significant proportion of cardiac ruptures, often requiring surgical intervention 1, 3
