Abstract：Objective To compare the clinical and echocardiographic features of different bicuspid aortic valve (BAV) morphologies, and to explore the differences between aortic valve dysfunction and aortic broadening location. Methods We performed a retrospective review of clinical and echocardiographic data about who presented with BAV between January 2011 and January 2017 in Beijing Chao-Yang Hospital. Results We identified 230 patients with BAV into three morphologies: R-N, right and non-coronary fusion (n=127); R-L, fusion of right and left coronary cusp (n=89); and L-N, left and non-coronary fusion (n=14). R-L type patients had higher proportion of aortic regurgitation (mild, moderate or severe) than that of R-N type patients (P<0.05). R-N type patients had higher proportion of aortic stenosis (mild, moderate or severe) than that of R-L type patients, but there was no significant difference (P>0.05). R-L type patients had larger aortic sinus dimensions than that of R-N (P<0.05). R-N type patients had larger ascending aorta dimensions than that of R-L, but there was no significant difference (P>0.05). Two aortic shapes were defined: normal type (n=40) and ascending dilatation (n=190). Any of the R-N, R-L and L-N, type A was more common than type N. Patients with R-N and type A had the highest proportion. Conclusion R-L type of BAV patients had higher incidence of aortic regurgitation and larger aortic sinus dimensions than that of R-N. BAV patients with R-N and type A had the highest proportion.
