Simple geometrical infarct exclusion technique with a single patch for postinfarction ventricular septal perforation

Area of Science:

• Cardiovascular Surgery
• Cardiac Repair Techniques
• Myocardial Infarction Complications

Background:

• Postinfarction ventricular septal perforation is a life-threatening complication of myocardial infarction.
• Traditional surgical repair methods face challenges with patch dehiscence and residual shunting.
• Acute intervention is critical for improving patient outcomes.

Purpose of the Study:

• To evaluate the efficacy of a novel three-dimensional surgical repair technique for postinfarction ventricular septal perforation.
• To assess the feasibility of using a pre-tailored equine pericardium patch in acute settings.
• To determine the early outcomes, including patch integrity and shunt prevention.

Main Methods:

• A consecutive series of six patients with postinfarction ventricular septal perforation underwent emergency surgical repair.
• A nontailored square equine pericardium patch was used, creating a pouch configuration.
• The patch was sutured circumferentially to viable muscle, excluding the infarcted area, followed by edge tailoring.

Main Results:

• The technique successfully achieved a three-dimensional repair in all six patients.
• No instances of patch dehiscence or significant residual shunting were observed.
• Satisfactory early results were obtained during the acute phase of myocardial infarction.

Conclusions:

• This simple, three-dimensional repair technique using an equine pericardium patch is effective for acute postinfarction ventricular septal perforation.
• The method minimizes tension on the suture line, preventing dehiscence and residual shunts.
• The technique offers a promising approach for managing this critical cardiac complication.
