Successful Percutaneous Closure of Gerbode Defect and Right Atrial-Aortic Fistula Following Infective Endocarditis.

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Infective endocarditis can lead to severe cardiac complications, including abscess formation and intracardiac shunts.
• Gerbode defects (ventricular septal defects with right atrioventricular valve involvement) and aortocardiac fistulas are rare but serious sequelae.

Observation:

• A patient presented with infective endocarditis complicated by a septal abscess, a Gerbode defect, and an atrial-aortic fistula.
• These combined intracardiac and aortocardiac communications represent a unique and challenging clinical scenario.

Findings:

• Successful percutaneous closure of both a Gerbode defect and an atrial-aortic fistula was achieved in a single interventional session.
• This represents the first reported instance of a minimally invasive, percutaneous correction for this specific combination of complex cardiac defects.

Implications:

• Percutaneous techniques offer a viable and potentially less invasive alternative to traditional open-heart surgery for complex congenital and acquired cardiac defects.
• This case expands the armamentarium of interventional cardiology for managing challenging valvular and septal abnormalities.
• Further research into percutaneous strategies for complex cardiac defects is warranted to establish efficacy and safety profiles.
