Cryopreserved valved femoral vein homografts for right ventricular outflow tract reconstruction in infants

Study cohort, groups, methods, and results. The 3 groups of patients (femoral vein homograft, pulmonary homograft, and aortic homograft) were compared for freedom from surgical reoperation using Kaplan–Meier analysis, freedom from percutaneous reintervention using Nelson–Aalen cumulative hazard analysis and multivariable Cox regression analysis for overall freedom from reintervention. The study revealed comparable freedom from surgical reoperation and a greater freedom from percutaneous reintervention for femoral vein homografts compared with other conduits. Younger age at conduit placement was an independent predictor of lower freedom from overall reintervention.
