Reintervention after repair of tetralogy of Fallot: a one-decade single-center experience

Abstract Background Reinterventions after tetralogy of Fallot repair (TOF) remains a common clinical problem. The objective this study was to evaluate types reintervention TOF and identify the risk factors for reinterventions. Methods This retrospective conducted from 2010 2022 included 171 patients with complete repair. Patients were grouped according occurrence into two groups: who did not have ( n = 138) those required 33). Results Median follow-up 36 (13–67) months. first in 33 patients. Freedom at 1, 3, 5, 7 years 91%, 85%, 81%, 76%, respectively. Surgical 12 transcatheter intervention 21 Second reinterventions 11 patients; 4 had surgery, .
