Complete Transcatheter Repair of Fallot’s Trilogy: A Case Report

Fallot’s trilogy is a relatively uncommon form of cyanotic congenital heart disease characterized by severe valvular pulmonary stenosis (PS), right ventricular hypertrophy and right to left interatrial shunt via an atrial septal defect (ASD) or patent foramen ovale (PFO). Historically, patients with the combination of these lesions were routinely treated by surgical correction. In recent times, transcatheter repair has become an increasingly attractive modality of treating such patients. There is limited experience with such combined transcatheter interventions, and from the scarce data available in published literature it seems that such approach has promising safety and efficacy. Herein, we describe a case of an 18 year old cyanotic male patient who was diagnosed of having severe valvular PS with supra systemic right ventricular pressures and reversed interatrial shunt via a large secundum ASD. We successfully treated him percutaneously with serial balloon pulmonary valvuloplasty, using single balloon and Inoue balloon techniques, followed by Amplatzer device closure of the ASD. The outcome was excellent with marked reduction of trans-pulmonary valvular gradient, complete cessation of shunting across the ASD, dramatic improvement of symptoms and completes disappearance of cyanosis. There were no procedure related complications and the benefits were sustained at follow up of three years. Our case demonstrates that transcatheter repair is a feasible, safe and effective alternative to surgery in selected patients with Fallot’s trilogy. With further experience, it may well become the standard of care in the management of such patients.
