Mechanical Complications of MI: Papillary Muscle Rupture, Free Wall Rupture, Ventricular Pseudoaneurysm

Myocardial infarction may lead to profound weakening of the involved wall and disruption of the infarcted segment. Depending on the location of the rupture, a variety of mechanical complications can result.

You will learn:

  • To describe the typical time course and clinical presentations of acute mitral regurgitation due to papillary muscle rupture
  • To define an appropriate diagnostic approach to the patient with a suspect acute mitral regurgitation complicating acute MI
  • To describe the potential therapeutic strategies and time course for acute mitral regurgitation
  • To list the potential consequences and complications of myocardial free wall rupture and ventricular pseudoaneurysm
