Postmyocardial infarction ventricular septal defect outcomes: Partial versus full presurgical hemodynamic support

Résumé fourni par la source

Objectives: Ventricular septal defects (VSDs) are life-threatening complications of myocardial infarctions (MIs), and the role of presurgical hemodynamic support remains unclear. This study compared outcomes of patients with post-MI VSDs in cardiogenic shock (CS) receiving different levels of presurgical hemodynamic support. Methods: Patients from January 1, 2011, to December 31, 2024, in CS with post-MI VSDs undergoing surgical patch repair at this single center were included. Patients with intra-aortic balloon pumps (IABP), Impella CP, or only pharmacologic presurgical hemodynamic support were placed in the partial support (PS) group; patients on venoarterial-extracorporeal membrane oxygenation (VA-ECMO) and/or Impella 5.0/5.5 before surgery were placed in the full support (FS) group. Discharge and 1-year clinical outcomes plus complications were compared between groups. Results: = .050). Postprocedural complications were similar between groups. Conclusions: Among patients with post-MI VSDs in CS, 1-year mortality was significantly lower among patients on full presurgical hemodynamic support as compared with partial presurgical hemodynamic support.
