Management of post-myocardial infarction ventricular septal rupture

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Ventricular septal rupture (VSR) following acute myocardial infarction (MI) carries a high mortality risk.
• Early surgical repair is the traditional recommendation for VSR, irrespective of hemodynamic status.
• Transcatheter device closure has emerged as a less invasive alternative to surgical VSR repair.

Purpose of the Study:

• To review the efficacy and safety of transcatheter device closure for VSR post-MI.
• To compare outcomes of transcatheter closure versus surgical repair in different clinical scenarios.
• To evaluate the optimal timing and patient selection for transcatheter VSR closure.

Main Methods:

• Review of existing literature and clinical data on transcatheter device closure for VSR.
• Analysis of procedural success rates, complication rates, and in-hospital mortality.
• Comparison of outcomes based on the timing of intervention (early vs. subacute phase) and patient characteristics.

Main Results:

• Transcatheter VSR closure demonstrates a high technical success rate with a low complication rate.
• Early transcatheter closure is associated with high in-hospital mortality.
• Optimal outcomes are observed in the subacute phase post-MI or for managing post-surgical patch leaks, potentially due to patient selection bias.

Conclusions:

• Transcatheter closure is a viable option for VSR, particularly in non-surgical candidates or for post-surgical leaks.
• A hybrid strategy combining early surgical closure with subsequent transcatheter management of residual leaks is favored.
• Long-term outcomes are favorable for patients who survive hospital discharge, regardless of the initial treatment approach.
