ABSTRACT

We present the first report in Mexico of three cases diagnosed as pulmonary atresia and intact ventricular septum that were treated by interventional cardiology. In order to prepare right ventricle for future biventricular surgical correction in two patients, we practiced mechanical and/or radiofrequency-assisted pulmonary valvotomy followed by balloon dilatation to assure outflow right ventricular patency; in one case, a stent was deployed into the infundibulum. In other patient, without right ventricular outflow and duct-dependent, we first attempted to assure patency, but it closed abruptly, and patient died. Finally, we present selection criteria to obtain optimal patient’s eligibility and results after consulting the medical literature and retrospective review of cases from the service. Opening and patency of right ventricular outflow in pulmonary atresia and intact ventricular septum by a combination of several interventional techniques is feasible and represents a new and promising option of treatment before surgical total repair in selected patients.
