immediate hemodynamic e ect, there are no long- term follow-up data. In addition, these techniques re- quire extensive pre-stenting. Later generations of the Sapien valve (Sapien XT and Sapien 3) are FDA-ap- proved for use in the aortic position and are being used by multiple centers for o -label implantation in the pulmonary position. Larger diameter Sapien valves (26 and 29 mm) allow for implantation in large dysfunctional native or patched RVOTs [26].
With a self-expanding platform design, the Venus P-valve can conform to a dilated and curved struc- ture of the RVOT. Furthermore, there is no need for pre-stenting to create a landing zone. Initial studies reveal that Venus P-valve implantation is feasible and safe in patients with severe PR after previous cor-
rection of tetralogy of Fallot, in whom a transannu- lar patch has been used. The valve is durable in the short-term and has not shown any stent fracture or valve malfunction 6–12 months after implantation. The valve restores early, sustained pulmonary com- petence with RV remodeling and improved clinical symptoms. Further long-term studies are warranted.
