Transcatheter Closure of Left Ventricular Outflow Tract-to-Left Atrium Fistula

Area of Science:

• Cardiovascular Interventions
• Interventional Cardiology
• Cardiac Surgery

Background:

• Aortic valve replacement, both surgical and transcatheter, can rarely lead to intracardiac fistulas.
• Intracardiac fistulas, specifically left ventricular outflow tract-to-left atrium fistulas, are uncommon but serious complications.
• Transcatheter closure of such shunts has demonstrated promising outcomes in prior reports.

Observation:

• This report details a specific case of a left ventricular outflow tract-to-left atrium fistula.
• The fistula occurred as a complication following surgical aortic valve replacement.
• The patient underwent a percutaneous closure procedure to address the fistula.

Findings:

• Successful percutaneous closure of a left ventricular outflow tract-to-left atrium fistula was achieved.
• An Amplatzer Vascular Plug II device was utilized for the transcatheter closure.
• The procedure was performed for a patient with a fistula post-surgical aortic valve replacement.

Implications:

• Percutaneous closure represents a viable and effective treatment strategy for post-aortic valve replacement fistulas.
• The use of devices like the Amplatzer Vascular Plug II facilitates minimally invasive management of these complex cardiac defects.
• This case highlights the expanding role of interventional cardiology in managing complications previously requiring open surgery.
