Double-patch technique for postinfarction ventricular septal perforation

Area of Science:

• Cardiovascular Surgery
• Cardiac Repair Techniques
• Medical Device Innovation

Background:

• Postinfarction ventricular septal perforation (VSP) is a life-threatening complication.
• Traditional surgical repair methods for VSP can be challenging, especially with extensive myocardial infarction.
• Effective VSP closure is critical to prevent hemodynamic instability and improve patient outcomes.

Purpose of the Study:

• To present a modified infarct-exclusion technique for surgical repair of postinfarction ventricular septal perforations.
• To evaluate the efficacy and safety of this novel dual-patch closure method with biological glue.
• To assess the suitability of this technique for VSP repair in cases of extensive fresh infarction.

Main Methods:

• A modified infarct-exclusion technique involving direct closure of the perforation with a small patch adjacent to a conventional patch.
• Application of biological glue between the two patches to ensure stable polymerization and adhesion.
• Surgical repair performed on patients with postinfarction ventricular septal perforations.

Main Results:

• The modified technique achieved stable polymerization and strong adhesion of the patch to the infarcted septum.
• No residual shunt was observed in any of the treated patients.
• Seven out of nine patients (77.8%) experienced good clinical outcomes following the procedure.

Conclusions:

• The modified infarct-exclusion technique offers a promising approach for VSP repair.
• This method is particularly well-suited for VSP associated with extensive fresh myocardial infarction.
• The dual-patch system with biological glue enhances suture line integrity and reduces shunt recurrence.
