Freedom from conduit malfunction was 100% and 83.3% at 1 and 8 years, respectively, while freedom from explantation was 83.3% and 74.2% at 2 and 8 years.

Overview

May inform conduit choice in select pediatric cases; leaves open durability in larger prospective studies.

Structured PICO

Does a bicuspid ePTFE valved conduit provide durable right ventricular outflow tract reconstruction in pediatric patients?

P
Population
12 pediatric patients undergoing right ventricular outflow tract reconstruction (RVOTR), mean age 43.5 ± 46.4 months, mean weight 13.4 ± 8.6 kg. Main diagnosis was tetralogy of Fallot with pulmonary atresia in 8 patients.
I
Intervention
Bicuspid expanded polytetrafluoroethylene (ePTFE) valved conduit (most common size 18 mm)
O
Outcome
Late conduit function (peak systolic pressure gradient, valve regurgitation, freedom from conduit malfunction, and freedom from explantation)hard clinical

The ePTFE bicuspid valved conduit maintains good competence over time, but progressive increases in pressure gradients remain the primary cause of late conduit failure and explantation.
