3D transesophageal echocardiography is a decision-making tool for the management of cardiogenic shock following a large postinfarction ventricular defect

Postinfarction ventricular septal defect (PIVSD) is a devastating mechanical complication following acute myocardial infarction. The management of this pathology is quite challenging, especially in case of complicated cardiogenic shock. The difficulties lie in the timing and type of intervention. Debates exist with regard to immediate versus deferring repair, as well as open repair versus percutaneous closure. The anatomic characteristics and hemodynamic consequence of PIVSD are important elements determining which strategy to adopt, since large septal defect (>15 mm) cannot be appropriately treated by percutaneous occluder devices limiting by their available size, while compromised hemodynamics usually require emergent repair or mechanical support "bridging to surgery". Herein, we report our experience of successful management of a case of cardiogenic shock complicating large PIVSD (38 mm) by delayed surgical repair bridged with Extracorporeal Membrane Oxygenation (ECMO) during 7 days. We emphasize the importance of 3-dimensional transesophageal echocardiography as a decision-making tool.
