Overview

May support tricuspid PTFE conduits for pediatric RVOT reconstruction; hypothesis-generating and requires randomized confirmation before practice change.

Structured PICO

Does a handmade tricuspid PTFE valved conduit prevent conduit dysfunction compared to a bicuspid conduit in patients requiring right ventricular outflow reconstruction?

P
Population
72 patients (30 males and 42 females; median age: 69 months) requiring right ventricular outflow reconstruction
I
Intervention
Handmade tricuspid polytetrafluoroethylene (PTFE) valved conduit
C
Comparator
Handmade bicuspid polytetrafluoroethylene (PTFE) valved conduit
O
Outcome
Conduit dysfunction and regurgitation assessed by echocardiography at early and mid-term follow-upsurrogate

In pediatric patients undergoing right ventricular outflow reconstruction, handmade tricuspid PTFE valved conduits demonstrated superior mid-term freedom from dysfunction compared to bicuspid designs.
