Abstract/OtherAbstract:
OBJECTIVES: We report the Melody valve implanted and/or expanded to 24mm diameter. BACKGROUND: The Medtronic Melody valve has been implanted up to 22mm in the pulmonary position for over a decade. METHODS: A retrospective chart review was performed on 82 patients who underwent Melody valve implant. Technical implant method, pre- and post-implant echocardiographic findings, and initial follow up were reviewed. RESULTS: Between 04/2008 and 12/2011, 13 Melody valves were successfully implanted in 11 patients, median age 35 years (range 16-61 yr), in the pulmonary (bioprosthetic valve, right ventricle to pulmonary artery conduit, native valve) position (n=9), tricuspid position (bioprosthetic valve n=3) and aortic position (bioprosthetic valve n=1). Ten valves were delivered on a 24mm balloon in balloon (BIB) catheter and 3 were implanted using a 22mm Ensemble balloon delivery system, followed by post dilation using a 24mm x 2cm Atlas balloon catheter. Post implant the median peak systolic gradient across the pulmonary valve was 7mmHg and median gradient across the tricuspid valve was 3mmHg. There was no change in gradient across the Melody valve in the aortic position where valve prosthesis-patient mismatch was present. Post implant intracardiac echocardiography demonstrated none or mild valve regurgitation. No more than mild regurgitation was noted at a median follow up of 9.5 months. CONCLUSIONS: The Melody valve can be implanted at 24mm in the stenotic/regurgitant bioprosthetic pulmonary, tricuspid, and aortic valve, dysfunctional right ventricle to pulmonary artery conduit, and the native right ventricular outflow tract, while the valve remains competent with only mild regurgitation. © 2013 Wiley Periodicals, Inc.
