TCT-426 CT predictor of periprocedural stroke related to transcatheter aortic valve replacement.

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...

Transcatheter aortic valve replacement and stroke.

Transcatheter 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...

Transcatheter Aortic-Valve Replacement.

Case History: A 77-year-old man presents with fatigue and shortness of breath with minimal exertion. He is brought into the examination room in a wheelchair due to shortness of breath with ambulation. He has a history of hypertension, diabetes mellitus, and coronary artery disease with prior stent to left anterior descending artery. Examination is notable for a harsh III/VI late-peaking systoli...

CT image-based engineering analysis of transcatheter aortic valve replacement.

DESPITE THE INCREASED GLOBAL EXPERIENCE WITH TRANSCATHETER AORTIC VALVE REPLACEMENT (TAVR), there remain 3 major adverse events. Aortic rupture (Fig. 1), coronary artery obstruction (Fig. 2), and paravalvular leakage (PVL) (Fig. 3) may occur with valve implantation. Oversizing or excessive radial expansion force with the TAVR stent may cause aortic rupture, whereas insufficient dilation may lea...
