ABSTRACT
Objective@#To compare the characteristics of aortic valve dysfunction and ascending aorta dimension in patients with different bicuspid aortic valve (BAV) morphology.@*Methods@#A total of 197 patients who underwent aortic valve replacement between April 2014 and March 2015 and were diagnosed with BAV by pathology were included, and their clinical data were retrospectively analyzed. Patients were divided into raphe+ group(109 cases) and raphe- group(88 cases) according to the presence or absence of raphe, and L-R group(fusion of left and right cusp, 125 cases) and L/R-N group(fusion of left or right and noncoronary cusp, 72 cases) according to fusion type of the cusps. The characteristics of aortic valve dysfunction and ascending aorta dimension in patients with different BAV morphology were compared.@*Results@#(1) Aortic stenosis incidence was lower in raphe+ group than in raphe- group(22.9%(25/109) vs. 69.3%(61/88), P<0.001). Aortic regurgitation incidence was higher in raphe+ group than in raphe- group (61.5%(67/109) vs. 22.7%(20/88), P<0.001). Incidence of type 1 of aortic root dilation was higher in raphe+ group than in raphe- group (23.9%(26/109)vs.10.2%(9/88), P=0.024). (2) Aortic stenosis incidence was lower in L-R group than in L/R-N group(29.6%(37/125) vs. 68.1%(49/72), P<0.001). Aortic regurgitation incidence was higher in L-R group than in L/R-N group (59.2%(74/125) vs. 18.1%(13/72), P<0.001). Incidence of type 3 of aortic root dilation was lower in L-R group than in L/R-N group(10.4%(13/125) vs. 37.5%(27/72), P=0.006). (3) Aortic stenosis incidence was lower in L-R patients than in L/R-N patients(15.1%(13/86)vs. 52.2%(12/23), P=0.001), and aortic regurgitation incidence was higher in L-R patients than in L/R-N patients in raphe+ group(73.3%(63/86)vs. 17.4%(4/23), P<0.001).@*Conclusion@#There is significant difference in the type of valvular dysfunction and ascending aorta dilatation in patients with different morphological characteristics of BAV.
