Preoperative Extracorporeal Membrane Oxygenation for Postinfarction Ventricular Septal Defect

Area of Science:

• Cardiology
• Cardiovascular Surgery
• Critical Care Medicine

Background:

• Ventricular septal defect (VSD) following myocardial infarction carries a high mortality rate.
• Despite advances, pharmaceutical, invasive cardiology, and surgical interventions have limitations.
• Urgent surgical repair is sometimes necessary for hemodynamically unstable patients.

Observation:

• Two patients with postinfarction VSD presented with cardiogenic shock and multiorgan failure.
• Optimal medical management did not stabilize their critical condition.
• Both patients required immediate intervention beyond standard care.

Findings:

• Venoarterial extracorporeal membrane oxygenation (VA-ECMO) was initiated for both patients.
• VA-ECMO provided hemodynamic support and end-organ perfusion.
• This mechanical circulatory support facilitated stabilization for subsequent surgical repair.

Implications:

• VA-ECMO can be a life-saving bridge therapy for severe postinfarction VSD.
• It allows for timely surgical intervention in critically ill patients.
• This approach may improve outcomes in complex VSD cases.
