A Strategy of Underexpansion and Ad Hoc Post-Dilation of Balloon-Expandable Transcatheter Aortic Valves in Patients at Risk of Annular Injury: Favorable Mid-Term Outcomes.
OBJECTIVES The aim of this study was to evaluate a strategy of intentional underexpansion of excessively oversized balloon-expandable transcatheter heart valves (THVs) in terms of clinical outcomes, valve function, and frame durability at 1 year. BACKGROUND Transcatheter aortic valve replacement requires the selection of an optimally sized THV to ensure paravalvular sealing and fixation witho...
متن کاملPre‐Implantation Balloon Aortic Valvuloplasty and Clinical Outcomes Following Transcatheter Aortic Valve Implantation: A Propensity Score Analysis of the UK Registry
BACKGROUND Aortic valve predilation with balloon aortic valvuloplasty (BAV) is recommended before transcatheter aortic valve implantation (TAVI), despite limited data around the requirement of this preprocedural step and the potential risks of embolization. This study aimed to investigate the trends in practice and associations of BAV on short-term outcomes in the UK TAVI registry. METHODS AN...
متن کاملEvaluation and management of paravalvular aortic regurgitation after transcatheter aortic valve replacement.
Paravalvular aortic regurgitation (PAR) negatively affects the prognosis after transcatheter aortic valve replacement (TAVR) with dramatically increased morbidity and mortality in patients with more than mild PAR. Because transcatheter heart valves are implanted in a sutureless fashion using oversizing to anchor the prosthesis stent frame at the level of the virtual aortic annulus, stent frame ...
متن کاملStructural integrity of balloon-expandable stents after transcatheter aortic valve replacement: assessment by multidetector computed tomography.
OBJECTIVES This study sought to evaluate the structural integrity of balloon-expandable stents used in transcatheter aortic valve replacement. BACKGROUND Underexpansion, deformation, or fracture of stent frames may affect transcatheter heart valve (THV) function and durability. METHODS Patients >1 year after transcatheter aortic valve replacement underwent multidetector computed tomography....
متن کامل1-Year Outcomes After Transcatheter Aortic Valve Replacement With Balloon-Expandable Versus Self-Expandable Valves: Results From the CHOICE Randomized Clinical Trial.
BACKGROUND The use of a balloon-expandable transcatheter heart valve previously resulted in a greater rate of device success compared with a self-expandable transcatheter heart valve. OBJECTIVES The aim of this study was to evaluate clinical and echocardiographic outcome data at longer term follow-up. METHODS The investigator-initiated trial randomized 241 high-risk patients with symptomati...
