Iatrogenic pulmonary valve insufficiency is a life-threatening complication and its treatment options pose another challenge. Easily accessible mechanical valves have high complication rates. Xenografts and homografts are expensive materials and are not readily accessible in case of emergency. Although monoand bileaflet reconstructions with autologous pericardium in the pediatric population has been reported frequently, trileaflet reconstruction of the pulmonary valve has not been reported in the literature, yet. Herein, we, for the first time, present a case of acute pulmonary valve insufficiency which was treated with the trileaflet reconstruction of the pulmonary valve.
