Surgical treatment of ventricular septal defect following myocardial infarction: a case report

Area of Science:

• Cardiology
• Cardiac Surgery

Background:

• Ventricular septal defect (VSD) is a rare mechanical complication post-myocardial infarction (MI).
• VSD post-MI is life-threatening, necessitating prompt diagnosis and hemodynamic stabilization.

Observation:

• A case of acute myocardial infarction complicated by ventricular septal rupture is presented.
• Immediate surgical closure was avoided; instead, a postponed surgery was performed 3 weeks post-VSD occurrence.

Findings:

• Optimal management involves invasive monitoring, inotropes, vasodilators, and intra-aortic balloon pump support.
• Delayed surgical closure, after at least 4 weeks for scar formation, yields better outcomes.
• The patient's condition was stabilized preoperatively with an intra-aortic balloon pump and inotropes, enabling successful delayed surgery.

Implications:

• This case highlights the efficacy of a delayed surgical approach for VSD post-MI.
• Aggressive medical management and hemodynamic support are crucial for patient survival pending surgery.
• Postponing surgery allows for scar tissue formation, potentially improving surgical success rates in managing this rare complication.
