ABSTRACT
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.

Se presentan los resultados de angioplastía por balón en estenosis de ramas pulmonares en 10 pacientes (edad promedio: 5 años, 10 meses), 9 de ellos habían sido previamente corregidos quirúrgicamente de su patología de base. En los 10 pacientes, se efectuaron 12 dilataciones, 8 procedimientos (7 pacientes) se estimaron exitoso, aumentando el diámetro de 6,7 mm (2-15 mm) a 13,9 (5-40 mm) y disminuyendo el gradiente de presión de 80 mmHg (50-120) a 36 (20-58 mmHg). En ninguno de ellos hubo complicaciones. La técnica es segura y está especialmente indicada en lesiones estenóticas de las ramas pulmonares residuales a la cirugía
