This systematic review explores the use of the Impella device in patients with post-infarct ventricular septal defect (VSD) prior to definitive treatment. Analyzing 68 patients across 20 studies, the Impella improved hemodynamic stability, reduced left ventricular strain, and delayed urgent intervention. Patients with surgically-placed Impella devices showed lower mortality and fewer complications compared to percutaneous alternatives. While effective, complications like bleeding and hemolysis must be carefully managed.
