Abstract
The mortality rate after the development of postinfarction ventricular septal defect remains high despite progress in pharmacologic therapy, invasive cardiology, and surgical techniques. We present a case series of six patients with preoperative venoarterial extracorporeal membrane oxygenation as a bridge to reparative surgical repair. Venoarterial extracorporeal membrane oxygenation allows to hemodynamically stabilize the patient, and safely delay the surgery. Delayed surgery might facilitate successful repair by allowing friable tissue to organize, strengthen, and become well-differentiated from surrounding healthy tissue; thus, definite repair can be performed safely. All patients were in cardiogenic shock and would otherwise require emergent cardiac surgery with associated risk. Three patients were discharged, with one hospital mortality of a patient who had a successful bridge to corrective surgery and died due to pulmonary artery rupture after a right ventricular assist device implantation. Two patients died before surgery while they were supported by venoarterial extracorporeal membrane oxygenation due to vascular complications. We discuss strategies how to optimize the management and function of the venoarterial extracorporeal membrane oxygenation to decrease the rate of adverse effects and optimize the outcomes of these patients.
