Overview

Low mortality supports intermediate-term safety of PTFE bicuspid valves; leaves open optimal thickness and durability in larger cohorts.

Key Points

  • To evaluate the safety, intermediate-term durability, and hemodynamic performance of custom-created polytetrafluoroethylene bicuspid pulmonary valves in right ventricular outflow tract reconstruction.
  • Retrospective cohort study of 126 consecutive patients (mean age 17.9 years, range 3.1–64.7 years; mean weight 55.4 kg) treated with polytetrafluoroethylene (PTFE) bicuspid pulmonary valve implantation for pulmonary insufficiency, stenosis, or repaired tetralogy of Fallot.
  • Tracked outcomes over a mean follow-up of 3.34 years (range 0–8.3 years), comparing the first 84 patients who received 0.6-mm porous PTFE valves with the subsequent 42 patients who received 0.1-mm nonporous PTFE valves.
  • Operative mortality occurred in 1 patient (0.8%) and late non-valve-related mortality in 3 patients (2.4%).
  • Valve replacement was required in 6 of 126 patients (4.8%) due to calcified and immobile leaflets, with all 6 failures occurring exclusively in the 0.6-mm PTFE cohort (6/84, 7.1%).
  • Echocardiographic follow-up of the 0.1-mm nonporous PTFE valves revealed enhanced leaflet pliability, improved mobility, and lower transvalvar gradients with zero reoperations.

Structured PICO

Does surgically created polytetrafluoroethylene (PTFE) bicuspid pulmonary valve implantation provide safe and effective outcomes in patients with pulmonary valve disease?

P
Population
126 patients with pulmonary insufficiency, pulmonary stenosis, or both (most commonly after previous repair of tetralogy of Fallot, n=71), mean age 17.9 years, mean weight 55.4 kg, treated at a single center in Florida.
I
Intervention
Surgically created polytetrafluoroethylene (PTFE) bicuspid pulmonary valve implantation (0.6-mm thickness in initial 84 patients, 0.1-mm thickness in subsequent 42 patients).
O
Outcome
Operative mortality, late mortality, and need for valve replacementhard clinical

Surgically created PTFE bicuspid pulmonary valves demonstrate acceptable intermediate-term safety and performance, with thinner 0.1-mm PTFE showing improved early echocardiographic outcomes compared to 0.6-mm PTFE.

Limitations

  • Long-term follow-up is necessary to determine the true value of this technique
