Abstract
Objectives. We report a multicenter experience with simultaneous right ventricular outflow tract (RVOT) stenting and transcatheter pulmonary valve implantation using the Melody valve ( Medtronic). Background. Prestenting the RVOT before Melody valve implantation is now the standard of care. Prestenting is usually performed as a separate step. The "one-step" technique for simultaneous landing zone stenting and Melody delivery was previously reported using only Max LD stents (Medtronic). We report a multicenter experience of simultaneous stenting and Melody implantation using multiple stent types in combination. Methods. This retrospective cohort study includes 33 patients from 3 centers who underwent simultaneous stenting and Melody valve implantation between 2017 and 2020. Key variables were compared with 31 patients from the same centers who underwent standard (non-simultaneous) prestenting followed by Melody implantation during the same time frame. Results. The 2 groups were similar in terms of age, weight, sex, and total procedure time. The 2 groups had similar clinical results and safety profiles, with no difference between the postimplantation right ventricle (RV) to pulmonary artery systolic pressure gradient, RV to aortic pressure ratio, and complication rate. The simultaneous group had lower radiation exposure as measured by dose area product. Up to 3 stents were safely placed simultaneously with a Melody valve. Conclusions. Simultaneous RVOT stenting and Melody valve implantation can safely be used to place up to 3 stents outside a Melody valve. This approach can simplify the catheterization procedure and potentially reduce radiation dose.
