Post-infarct ventricular septal defect (VSD) carries high mortality. Since emergent repair of post-infarct VSD is challenging, hemodynamic stabilization utilizing temporary mechanical circulatory support crucially provides time to delay intervention and allows necessary scar tissue formation which improves the fragility of myocardium and leads to a definitive repair. To date, there remains no standard for achieving hemodynamic stability, including usage and mode of temporary mechanical circulatory support. We describe a patient with acute post-infarct VSD in cardiogenic shock successfully supported with Impella 5.5 for 67 days as a bridge to surgical repair and coronary artery bypass grafting.
