Successful percutaneous closure of paraprosthetic aorto-right ventricular leak using the Amplatzer duct occluder.
A 55-year-old male with persisting aorto-right ventricular paraprosthetic leak after mitroaortic valve replacement was hospitalized for recurrent heart failure. Depressed left ventricular ejection fraction and severe pulmonary hypertension with increased right and left ventricular filling pressures were associated with significant left to right shunting through the leak. Elective closure of the leak was obtained with a 6-4 mm Amplatzer duct occluder. No complications were observed, and the patient experienced complete resolution of heart failure symptoms, with NYHA class I heart failure 12 months after discharge.
