[Postinfarction ventricular septal perforation; tips of patch closure]

Area of Science:

• Cardiovascular Surgery
• Cardiac Repair Techniques
• Myocardial Infarction Complications

Background:

• Surgical repair of postinfarction ventricular septal perforation (VSP) is complex.
• Low output syndrome (LOS) and residual shunts are significant postoperative complications.
• Existing methods include patch closure and David procedures.

Observation:

• A modified patch closure technique is detailed.
• Key modifications include minimal septal resection and specific suture placement.
• A large xeno-pericardial patch with an extended skirt is utilized to manage potential myocardial cutting and shunt flow.

Findings:

• The technique was applied to six patients with postinfarction VSP.
• The modified approach aims to prevent residual shunts by leveraging left ventricular pressure.
• Postoperative outcomes were reported as good, suggesting efficacy in preventing complications.

Implications:

• This technique offers a potential strategy to reduce LOS and residual shunts after VSP repair.
• The use of a xeno-pericardial patch skirt may provide a novel method for managing intraoperative challenges.
• Further studies could validate this approach in a larger patient cohort.
