Ascending Aortic Dilation in BiAV After TAVR
Ascending Aortic Dilation in BiAV After TAVR
This study sought to evaluate changes in ascending aorta size after transcatheter aortic
 valve replacement (TAVR) in patients with bicuspid aortic valve (BiAV) compared with patients
 with tricuspid aortic valve (TAV).
The growth rate of ascending aorta was calculated as annual growth rate using baseline and
 the last echocardiography. The difference in ascending aorta growth rates between the two
 groups (BiAV and TAV) were analyzed by independent t-test.
Inclusion Criteria:

 -  Severe AS who underwent TAVR

 Exclusion Criteria:

 -  ascending aorta more than 50mm
