Introduction Right ventricular (RV) dilatation is the determining prognostic factor in the long-term follow up of patients with repaired Tetralogy of Fallot (TOF). The objective of this study is to analyze whether the results vary depending on the timing of the complete repair and on the surgical technique applied. Material–Methods This is a retrospective longitudinal study in which patients with standard TOF were divided into 3 groups depending on their age at surgical repair: group 1 = Early repair ( n = 12,1-8 months), group 2 = Late repair ( n = 26, > 8 months), and group 3 = Late repair with previous palliative surgery ( n = 17, > 8 months). Clinical, echocardiographic and cardiac magnetic resonance (CMR) data from patients that had received complete reparative surgery in our institution from January 2000 to March 2014 were analyzed and compared. Results 55 patients with echocardiogram and CMR studies (13.39 ± 3.59 years) were reviewed. All patients had at least moderate pulmonary regurgitation (PR). We observed a positive correlation between PR and right ventricular end-diastolic volume ( r 2 = 0.418; p = 0,004). Group 3 had more severe right ventricular dilatation than patients in groups 1 and 2 ( p = 0.001). No differences in right ventricular end-diastolic volume, PR, and pulmonary trunk dimensions were observed between groups 1 and 2. Patients in group 3 had a longer hospital stay. Conclusions Although all patients from our cohort had significant PR, age at surgery was not related to RV or pulmonary trunk dilatation. Previous palliative surgery was associated with more severe right ventricular dilatation and longer hospital stays. No differences were observed between early and late repair groups. Our study suggests that postponing TOF repair to a late stage does not improve the degree of PR or long-term morbidity from RV dilatation. Palliative surgery should be avoided if possible.
