Why the study?
What are the clinical outcomes and failure rates of various valved conduits used for right ventricular outflow tract reconstruction?
Population
Patients undergoing right ventricular outflow tract (RVOT) reconstruction
Comparison
Valved conduits vs Comparison among different conduit types
Design
Review
Follow-up
Up to 15 years
Key result
Conduit failure rates at 2 years were 9-55% for homografts, 35% for stented xenografts, and 25% for stentless xenografts, with 5-year freedom from reoperation varying widely by conduit type.

Variable conduit durability may inform individualized RVOT reconstruction; leaves open optimal choice pending prospective trials.
What are the clinical outcomes and failure rates of various valved conduits used for right ventricular outflow tract reconstruction?
Homografts remain the most commonly used RVOT conduit with excellent characteristics, while alternatives like Contegra and Hancock offer acceptable intermediate to long-term results despite inevitable eventual conduit failure.
Yuan et al. (2008) conducted a review in Right ventricular outflow tract (RVOT) reconstruction. Valved conduits (homograft, stented xenograft, stentless xenograft, autologous tissue) vs. Various conduit types compared to each other was evaluated on Conduit failure and actuarial freedom from reoperation. Conduit failure rates at 2 years were 9-55% for homografts, 35% for stented xenografts, and 25% for stentless xenografts, with 5-year freedom from reoperation varying widely by conduit type.
