Impact of Straight Ascending Aorta Length on Difficulty of Transcatheter Heart Valve Crossing during Transcatheter Aortic Valve Replacement
Objective: Although most transcatheter aortic valve replacement (TAVR) procedures for symptomatic severe aortic valve stenosis (AS) can be performed successfully, there are some challenging cases with several specific anatomical characteristics, such as a horizontal aorta, aortic dilatation, and bicuspid aortic valve. A short, straight ascending aorta length (SAAL) can cause the transcatheter heart valve (THV) device to lack the distance required to orient in the direction of the aortic annulus, leading to failure to cross the aortic valve. This study aimed to examine the characteristics of SAAL and its association with the difficulty of THV device crossing.
