This information was received through literature article "bicuspid pulmonary valve implantation using polytetrafluroethylene membrane: early results and assessment of the valve function by magnetic resonance imaging" published in the european journal of cardio-thoracic surgery, 2 july 2012.The objectives of this study were to evaluation the early results of polytetrafluoroethylene (ptfe) bicuspid pulmonary valve (pv) implantation and to better define the function of this valve by magnetic resonance imaging.Bicuspid pv implantation was performed using a 0.1 mm-thickness gore preclude pericardial membrane.The bicuspid valve is cut from a folded sheet of ptfe membrane.The width of the free edge is 1.8 times the anticipated valve diameter.The length was adjusted to the length of the rvot incision.After placing two anchoring sutures at the level of pv annulus, the posterior leaflet is sewn from its apex towards the free edge using 5/0 polypropylene continuous suture.The anterior leaflet is sewn from its apex towards the free edge, beginning at the vertex of the rvot incision.The article reports two cases of leaflet dehiscence that resulted in a moderate amount of pulmonary valve regurgitation.The dehiscence occurred at the apical portion of the anterior leaflet in both patients.It is possible that undue tension on the suture line might have caused the dehiscence by cutting through the thin ptfe membrane.We think that it is important to make the length of the anterior leaflet slightly redundant to avoid tension on the suture line.
