Balloon Sizing for Transcatheter Aortic Valve Replacement*
نویسنده
چکیده
When the association of paravalvular leak (PVL) and increased mortality was first described in 2012 at the 2-year PARTNER I presentation (1), the transcatheter aortic valve replacement (TAVR) community reacted with great concern that this promising technology was beginning to show signs of weakness. Since then, a great deal of data has been reported from multiple registries confirming this association. Despite this research, a causal relationship between PVL and mortality has not been proved, and the most effective method of preventing PVL is still unknown.

Preparatory balloon aortic valvuloplasty during transcatheter aortic valve implantation for improved valve sizing.
OBJECTIVES This study sought to evaluate whether supra-aortic angiography during preparatory balloon aortic valvuloplasty (BAV) improves valve sizing. BACKGROUND Current recommendations for valve size selection are based on annular measurements by transesophageal echocardiography and computed tomography, but paravalvular aortic regurgitation (PAR) is a frequent problem. METHODS Data of 270 ...

Computed tomography (CT) plays an important role in the workup of patients who are candidates for implantation of a catheter-based aortic valve, a procedure referred to as transcatheter aortic valve implantation (TAVI) or transcatheter aortic valve replacement (TAVR). Contrast-enhanced CT imaging provides information on the suitability of the peripheral access vessels to accommodate the relativ...

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...

OBJECTIVES This study compared cross-sectional three-dimensional (3D) transesophageal echocardiography (TEE) to two-dimensional (2D) TEE as methods for predicting aortic regurgitation after transcatheter aortic valve replacement (TAVR). BACKGROUND Data have shown that TAVR sizing using cross-sectional contrast computed tomography (CT) parameters is superior to 2D-TEE for the prediction of par...
