[Post-myocardial infarction ventricular septal defect].

Post-myocardial infarction ventricular septal defect corresponds to the rupture of the ventricular septum between the healthy and infarcted parts. It is a rare complication still associated with a high mortality rate. Its diagnostic should be evoked in case of pathologic cardiac auscultation and confirmed by emergent transthoracic echocardiography. Hemodynamic stabilisation, mainly with the insertion of an intra-aortic balloon pump is the first step in the management. The subsequent modality of closure, either surgical or transcatheter, as well as the ideal timing should be discussed in the Heart team. Successful closure decreases the 30-day mortality rate to 30-40 %.
