[Post-infarction ventricular septal defect treated during the acute phase by transcatheter closure with an Amplatzer...

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Large anterior myocardial infarction can lead to life-threatening complications such as ventricular septal defects (VSDs).
• Early intervention is crucial for managing acute cardiac events and their sequelae.
• Transcatheter techniques offer minimally invasive options for structural heart disease repair.

Observation:

• A 75-year-old male presented with a large anterior myocardial infarction complicated by a VSD.
• The VSD was successfully closed within 48 hours using a transcatheter approach with an Amplatzer septal occluder.
• Coronary angioplasty with stent implantation was performed for a blocked left anterior descending artery.

Findings:

• Transcatheter VSD closure achieved a successful outcome with minimal residual shunting.
• Despite successful VSD closure and revascularization, the patient experienced sepsis and ventricular failure.
• The patient demised 7 days post-procedure due to complications of sepsis and cardiac decompensation.

Implications:

• Transcatheter VSD closure is a viable option for hemodynamically significant defects post-myocardial infarction.
• Early mechanical complication management does not preclude later systemic or cardiac decompensation.
• Further research is needed to optimize outcomes and reduce mortality in complex post-MI VSD cases.
