Demographics of repaired tetralogy of Fallot (rTOF) cohort

	TOF-PS (n = 47)	TOF-PA (n = 11)
Age of complete repair (years), IQR	1.4 (0.3–1.9)	1.2 (0.2–1.7)
Type of surgery
Initial Blalock-Taussig-Thomas shunt palliation	8 (17%)	3 (27%)
Transannular patch	39 (83%)	3 (27%)
Infundibular patch	7 (15%)	0 (0%)
Right ventricle-to-pulmonary artery conduit	1 (2%)	8 (72%)
Subsequent pulmonary valve replacement	8 by surgery (17%)	2 by surgery, 1 by catheterization (27%)

The cohort consisted of patients with either tetralogy of Fallot-Pulmonary Stenosis (TOF-PS) or tetralogy of Fallot-Pulmonary Atresia (TOF-PA). 10 patients already had pulmonary valve replacement
