At a median follow-up of 589 days, there were no conduit reoperations, with an average postoperative peak pressure gradient of 18.6 ± 9.0 mm Hg and none or trace regurgitation in 81% of patients.

Why the study?

Use of ePTFE valved conduits in the pulmonary position during congenital heart defect correction has grown due to promising longevity, prompting the description of a standardized creation and implantation technique and its early outcomes.

Does standardized trileaflet ePTFE valved conduit placement provide satisfactory hemodynamic function and avoid reoperation in patients with congenital heart defects?

Population

Overview

May support use in congenital pulmonary reconstruction; leaves open durability beyond 2 years and need for comparative trials.

Structured PICO

Does standardized trileaflet ePTFE valved conduit placement provide satisfactory hemodynamic function and avoid reoperation in patients with congenital heart defects?

P
Population
100 consecutive patients undergoing expanded polytetrafluoroethylene (ePTFE) valved conduit placement in the pulmonary position for congenital heart defects, mean age 28 ± 13.2 years. Indications included pulmonary valve replacement (n=68), conduit change (n=25), and part of total repair (n=7).
I
Intervention
Simplified standardized trileaflet expanded polytetrafluoroethylene (ePTFE) valved conduit placement in the pulmonary position
O
Outcome
Conduit function evaluated by transthoracic echocardiography (peak pressure gradient and regurgitation) and conduit reoperation at early follow-upsurrogate

Standardized trileaflet ePTFE valved conduit placement in the pulmonary position demonstrates excellent early hemodynamic function and freedom from reoperation.
