Transcatheter Aortic Valve Replacement: A Review Article
Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...
متن کاملBioprosthetic Valve Fracture Improves the Hemodynamic Results of Valve-in-Valve Transcatheter Aortic Valve Replacement.
BACKGROUND Valve-in-valve (VIV) transcatheter aortic valve replacement (TAVR) may be less effective in small surgical valves because of patient/prosthesis mismatch. Bioprosthetic valve fracture (BVF) using a high-pressure balloon can be performed to facilitate VIV TAVR. METHODS AND RESULTS We report data from 20 consecutive clinical cases in which BVF was successfully performed before or afte...
متن کاملValve-in-Valve Replacement Using a Sutureless Aortic Valve
BACKGROUND We present a unique case of a 61-year-old female patient with homograft deterioration after redo surgery for prosthetic valve endocarditis with root abscess. CASE REPORT The first operation was performed for type A dissection with root, arch, and elephant trunk replacement of the thoracic aorta. The present re-redo surgery was performed as valve-in-valve with a sutureless aortic biop...
متن کاملIncidence, Timing, and Predictors of Valve Hemodynamic Deterioration After Transcatheter Aortic Valve Replacement: Multicenter Registry.
BACKGROUND Scarce data exist on the incidence of and factors associated with valve hemodynamic deterioration (VHD) after transcatheter aortic valve replacement (TAVR). OBJECTIVES This study sought to determine the incidence, timing, and predictors of VHD in a large cohort of patients undergoing TAVR. METHODS This multicenter registry included 1,521 patients (48% male; 80 ± 7 years of age) w...
متن کاملTranscatheter Aortic Valve Replacement
With the worldwide number of TAVR procedures rapidly approaching 200,000, coupled with an amassed knowledge spanning over a decade, we are able to now reflect on the evolution of TAVR and how changes in technology, operator/institution experience, and patient selection have ultimately affected clinical outcomes. With this in mind, in this issue of JACC: Cardiovascular Interventions, Beohar et a...
