Transcatheter Closure of an Aortic-right Ventricular Fistula with an Amplatzer Duct Occluder II (ADO II)

Abstract

The treatment of choice for an aortic-right ventricular fistula is surgical repair; however, transcatheter treatment of left to right shunt using an occluding device has recently increased. We report a 12-year-old boy who weighed 45 kilograms and presented with an asymptomatic heart murmur. He was diagnosed with aortic-right ventricular fistula. Color Doppler echocardiography revealed a 3-millimeter aortic-right ventricular fistula that was 5 mm from the right coronary artery, left to right flow, pressure gradient of 100 millimeters of mercury (mmHg); good left ventricle function, ejection fraction of 70.0%, and right ventricular systolic pressure of 40 mmHg (SBP 120 mmHg) with a normal coronary artery pattern. He successfully underwent transcatheter closure using an Amplatzer Duct Occluder II with transesophageal echocardiography and fluoroscopy guidance.
