Treatment of pulmonary vein stenosis with expanded polytetrafluoroethylene covered stents

Abstract

Atrium expanded polytetrafluoroethylene covered stents were implanted in the stenotic pulmonary veins (n = 5) of three patients. Use of this device was feasible in infants and the procedure was well-tolerated without major complications. The majority (4/5) of covered stents remained patent for at least 3 months after implantation. Stents remain patent in the two surviving patients 6 months after deployment.
