Figure 1. Graph displaying the study flow with the total number of 407 patients after repair of tetrology of Fallot (TOF) who were originally included in the national TOF multicenter cardiovascular magnetic resonance (CMR) study. A total of 70 patients were excluded because of an incomplete data set.

Of the 337 patients, another 36 had to be excluded as no follow‐up data were available within the database of the national registry for congenital heart disease (CHD). Finally, of 296 patients with a median follow‐up time of 10.1 (range, 0.1–12.9) years, 19 experienced adverse events. Note that 5 patients were excluded in the outcome analysis as these patients exhibited adverse events before the CMR study. Pulmonary valve replacement (PVR) procedures were performed in 119 of 292 patients during the follow‐up. CPET indicates cardiopulmonary exercise testing; echo, echocardiographic; EP, electrophysiologic study; ICD, implantable cardioverter‐defibrillator; N, number of patients; RVOT, right ventricular outflow tract; TOF/PA, pulmonary atresia with ventricular septal defect (Fallot type); and VT, ventricular tachycardia.
