Percutaneous closure of a postinfarction ventricular septal defect and an iatrogenic left ventricular free-wall...

Area of Science:

• Cardiovascular Interventions
• Interventional Cardiology
• Structural Heart Disease

Background:

• Postinfarction ventricular septal defect (VSD) is a rare but serious complication of myocardial infarction.
• Percutaneous closure offers a less invasive alternative to surgical repair for VSDs.
• Complex cardiac defects require advanced interventional techniques.

Observation:

• An 83-year-old woman presented with a postinfarction VSD after anterior myocardial infarction and percutaneous coronary intervention.
• The patient experienced an iatrogenic left ventricular free-wall perforation during the VSD closure procedure.
• Two Amplatzer muscular VSD occluders were utilized for simultaneous defect closure.

Findings:

• Successful percutaneous closure of both the postinfarction VSD and the iatrogenic left ventricular free-wall perforation was achieved.
• The combined procedure was completed in a single interventional session.
• The use of Amplatzer devices facilitated the closure of these complex, coexisting defects.

Implications:

• Percutaneous closure is a viable and effective strategy for managing complex postinfarction VSDs, even with associated complications.
• This case highlights the potential for simultaneous closure of multiple cardiac defects during a single interventional procedure.
• Advanced device technology enables treatment of challenging structural heart conditions, improving patient outcomes.
