We conducted a retrospective review of patients who underwent valved homograft conduits (VHC) for right ventricular outflow tract (RVOT) reconstruction at our center. Long-term outcomes were analyzed, and risk factors affecting the long-term durability of VHC were explored. Kaplan-Meier survival curves were used to evaluate survival, freedom from VHC reintervention, and freedom from VHC dysfunction. Multivariate Cox proportional hazards regression model was used to analyze the risk factors for late VHC dysfunction. A total of 290 patients who underwent VHC for RVOT reconstruction in our center were enrolled. Seven patients occurred early death, all of which were in the non-Ross group. Two hundred and sixty-five patients were followed up for 85 (0.3-176.0) months. Six patients occurred late death, all in the non-Ross group. Six patients underwent VHC reintervention. During the follow-up period, 52 patients developed VHC dysfunction. Freedom from VHC dysfunction was higher in the Ross group than in the non-Ross group in the whole cohort. Multivariate Cox regression analysis showed that age < 6 years and non-Ross operation were independent risk factors for VHC dysfunction. Freedom from VHC dysfunction was higher in the Ross group than in the non-Ross group in patients younger than 6 years of age at surgery. However, there was no significant difference in freedom from VHC dysfunction between the two groups in patients older than 6 years. Long-term outcomes of VHC for RVOT reconstruction are satisfactory. Age < 6 years and non-Ross operation are independent risk factors for VHC dysfunction. The long-term survival rate and durability of VHC in Ross group were better than those in non-Ross group. The advantage of long-term durability of VHC in the Ross group was mainly reflected in patients aged < 6 years at operation.
