Functional uni‐ventricular heart due to post‐myocardial infarction ventricular septum rupture

Abstract

Ventricular septum defect (VSD) is an often lethal complication caused by myocardial infarction. We report a rare case of post-myocardial infarction ventricular septum rupture in a patient after extracorporeal cardiopulmonary resuscitation (eCPR).In the bedside echocardiography after VA ECMO cannulation, we noticed the circular, hypertrophied left ventricle with the disintegrated inter-ventricular septum (maximum dehiscence 3.3 cm), accompanied by decreased left-ventricular ejection fraction and the right ventricle being compressed by the left ventricle's free septal wall.There was no pressure-relevant inter-ventricular separation resulting in left-to-rightshunting and therefore resulting in a fully functional uni-ventricular heart.
