Ventricular septal rupture complicating acute myocardial infarction following percutaneous coronary intervention

Abstract

Ventricular septal rupture (VSR) is a rather rare, but at the same time very dreadful complication of acute myocardial infarction in the percutaneous coronary intervention (PCI) era and only limited evidence exist on the optimal treatment of this critical medical condition. VSR is less common following successful early thrombolysis and PCI occurring in myocardium supplied by infarct-related artery (IRA). We report two well-documented cases of successful VSR treatment which will provide valuable information for clinical practice especially due to the longtem follow-up. Both cases underwent delayed elective surgical closure of VSR. This report clearly describes the incidence, potential risks and timing of occurrence, clinical features, and outcomes of ventricular septal rupture complicating acute myocardial infarction (AMI) after PCI. Hence the topic of this report is of great importance. Although the prognosis of patients who develop VSR is generally grave without immediate surgical repair, both our patients remained hemodynamically stable at discharge and during follow-up of more than 4 years.Keywords: ventricular septal rupture, acute myocardial infarction, percutaneous coronary intervention c a s e r e p o r t
