Abstract: Objective: To investigate the clinical value of MSCT virtual endoscopy (CTVE) in diagnosis of adult bicuspid aortic valve deformity. Methods: From March 2010 to August 2015, eight cases with calcification of aortic valve underwent 128-slice spiral CT coronary angiography (CTCA) examination were presented bicuspid aortic valve deformity intuitively under CTVE. The thickness of aortic valve and the maximum diameter of the ascending aorta were measured. Results: Eight cases with calcification of aortic valve were presented bicuspid aortic valve deformity intuitively under CTVE, through the CTCA, other merger cardiovascular malformations can be found, and included 6 cases of aortic widened, one case of abnormal left coronary artery origin. And thickened aortic valve was found in 5, no thickening of the aortic valve in 3.Conclusion: Application of CTVE in CTCA examination visualize the structure of the aortic valve, and can find other vascular malformation, observe coronary artery, so as to rule out other diseases. Moreover, CTVE and color Doppler echocardiography can complement each other
