Abstract:
Objective To compare aortic root anatomical characteristics between severe aortic valve stenosis (AS) and aortic regurgitation (AR) patients, and to provide useful information for transcatheter aortic valve replacement (TAVR) device designs and procedural techniques for treatment of AR. Methods Consecutive patients admitted between April 2014 to May 2016 with severe AS or AR and planned to undergo transcatheter aortic valve replacement were included. There were a total of 57 AR and 113 AS patients. All patients underwent multi-detector computed tomographic imaging and echocardiography examinations. Results The mean aortic annulus diameter in AR patients was slightly but significantly larger than AS patients[ (26.4±3.7) mm vs. (25.2±2.9) mm, P=0.001]. The mean diameters of the ascending aorta[ (38.3±6.9) mm vs. (33.9±6.7) mm, P<0.001]and Valsalva sinus[ (38.9±6.9) mm vs. (32.7±4.5) mm, P<0.001] in AR patients were larger than in AS patients. The left coronary ostia height was of no significant difference between the 2 groups [ (12.5±3.7) mm vs. (13.4±3.2) mm, P=0.08] and the right coronary ostia height was higher in the AR group than in the AS group [ (17.5±5.0) mm vs. (15.3±3.3) mm, P=0.001]. Conclusions The anatomical aortic root data from patients with AS or AR in the present study may provide useful information for transcatheter aortic valve replacement device designs and procedural techniques for treatment of AR.
