RESUMO

OBJECTIVE: We report the percutaneous closure of the pulmonary artery with residual shunt in patients with Fontan type circuit. METHOD: Patients aged 9 and 11 years, with SaO2 of 88 and 96%, respectively. One of them coursing with headaches and functional class II. Both patients with total cavopulmonary anastomosis and fenestrated extracardiac conduit and permeable pulmonary artery (pulsatile Fontan). An Amplatzer duct-occluder device was implanted in the pulmonary artery entering from the femoral vein. Follow-up by means of clinical examination, imaging, and catetherization was pursued. RESULTS: Case 1, patency fenestration, Qp/Qs: 0.7/1. Case 2, closed fenestration, Qp/Qs; 1.3/1. We obtained immediate occlusion with 6/4 and 8/6 devices, respectively; pressure recordings revealed modification of the arterial morphology to biphasic; pulmonary pressure dropped 2 mm Hg in the first patient, without alteration in the second case; no changes in SaO2 were registered. Time of fluoroscopy was 57 and 45 minutes, respectively. Follow-up was maintained for 2.8 and 2.3 years, respectively. In patient 1, headaches disappeared and the fenestration was occluded with an Amplatzer septal-occluder one year later, raising SaO2 to 96%; no complications occurred nor was recanalization of the pulmonary artery needed in either case. CONCLUSIONS: Percutaneous occlusion of patent pulmonary artery in patients with Fontan type circuit is a feasible and effective procedure, and avoids overload of the single ventricle.

RESUMO

La fístula coronaria congénita es una patología poco frecuente y en general asintomática, por lo que muchas veces se diagnostica por un hallazgo incidental. Con dependencia de la repercusión hemodinámica, algunos siguen una conducta conservadora, otros indican tratamiento quirúrgico o, más recientemente, oclusión por cateterismo. Se presenta el caso de una paciente con una gran fístula coronaria-cameral, que se trató mediante embolización percutánea con dispositivo Amplatzer vascular plug. No se presentaron complicaciones durante el procedimiento ni en el seguimiento.


Congenital coronary fistula is an infrequent condition generally asymptomatic, which is mostly diagnosed by an incidental finding. Depending on the presence of hemodynamic compromise, coronary fistulas may be treated with a conservative approach, with surgery or, recently, with transcatheter closure. We present a case report of a patient with a large coronarycameral fistula treated with percutaneous embolization with Amplatzer vascular plug. No complications developed during the procedure and follow-up.

RESUMO

Objetivo: Presentar nuestra experiencia con el empleo de stent para mantener la permeabilidad ductal en cardiopatías congénitas dependientes del ductus. Método y resultados: En tres pacientes de entre 2 y 9 días de vida con atresia pulmonar se colocaron cuatro stents por cateterismo, sin complicaciones. El tiempo de seguimiento promedio fue de 411 días (123 a 721 días). Dos stents se redilataron exitosamente. Un paciente fue sometido a cirugía, uno interrumpió sus controles cuatro meses después y otro espera cirugía. La saturación promedio aumentó del 61 por ciento al 80 por ciento. Conclusiones: En pacientes con cardiopatías cuya circulación depende del ductus arterioso, el implante del stent fue factible y efectivo a corto y mediano plazos.
