Abstract

OBJECTIVE: Pulmonary regurgitation may cause progressive right ventricular dilatation and dysfunction in adult patients previously repaired for tetralogy of Fallot. To assess the optimal surgical timing, the impact of the right ventricular restoration with a new surgical ventriculoplasty technique is evaluated following TFO repaired adult patients with severe pulmonary regurgitation and right ventricular dilatation. METHODS: Sixteen patients with severe pulmonary valve regurgitation (PVR) and right ventricular dilatation with RVOT aneurysm underwent right ventricular remodelling since January 2002. Each underwent preoperative evaluation by Doppler echocardiography, magnetic resonance imaging (MRI), and right ventricular myocardial acceleration during isovolumic contraction (IVC). The surgical procedure included pulmonary valve implantation and RVOT restoration achieved by removal of the aneurysm tissue, coupled with a ventriculoplasty to reduce volume, accomplished by creating a satisfactory RVOT dimension by placing with 2-0 Gortex suture to allow acceptance of a 26 Hegar dilator to avoid restriction. Nine patients had associated surgical procedures. RESULTS: All patients survived the operative procedure and underwent a 16-month follow-up interval. A reduction of cardio thoracic index and a clinical improvement occurred in each patient. Significant reduction of RVEDV and RVESV and increased right ventricular ejection fraction was observed. CONCLUSIONS: This preliminary database implies that the right ventricular restoration is a simple and effective procedure, and introduces a structural component that should be added in repaired TFO patients with right ventricular dilatation and underlying aneurysm or akinesia of the right ventricular outflow tract.
