Percutaneous pulmonary valve implantation

Immediate and long-term outcomes of percutaneous transcatheter pulmonary valve implantation

“…Prestenting decreases the number of stent fractures observed in follow-up [8,19]. However, some authors [20] point out possible valve compression in significant homograft calcifications even with standard presenting.…”

“…Two different types of implantable valves were used in the study. Edwards-Sapien valve -bovine pericardial valve mounted within stainless steel stent is available in diameters of 23, 26 and recently in 29 mm [8]. In 8 patients valve implantation was postponed for 2-3 months after prestenting in order to allow stent fixation.…”

“…Potential coronary compression was excluded with simultaneous balloon inflation in the RVOT and selective coronary angiography or aortic root angiography. In adherence to the recommendations [7][8][9], all patients underwent routine prestenting to create a landing zone for subsequent TPVR. Two different types of implantable valves were used in the study.…”

“…All procedures were performed according to previously described methods [2,5,[8][9][10]. General anesthesia with endotracheal intubation, antibiotic prophylaxis and intravenous heparin (100 IU/kg) were used in all patients.…”

“…Moreover, an increasing number of publications on TPVR in non-standard pulmonary positions have been published [5,6]. Currently, there are two commercially available types of percutaneous implantable pulmonary valves on the European market, the more popular Melody valve (Medtronic Minneapolis, Minnesota, USA) and the less used Edwards-Sapien valve (Edwards Lifesciences LLC, Irvine, California, USA) [7,8].…”
