A 50-year old male, with congestive heart failure history referred severe aortic regurgitation due to bicuspid valve diagnosed by transesophageal echocardiography (Fig. 1). A CT scan using 16-row multidetector CT was performed preoperatively.

Fig. 1. Supraannular view of transesophageal echocardiography shows the bicuspid aortic valve. It depicted the calcified raphe (arrow) of large single cusp and normal size left coronary cusp (arrow head). There is a large gap between the enlarged single cusp and left coronary cusp which may cause severe aortic regurgitation.

Three-dimensional CT imaging could demonstrate the anatomical findings of bicuspid aortic valve clearly (Fig. 2).

Fig. 2. Supraannular view of three-dimensional image using 16-row multidetector computed tomography shows the entire image of bicuspid aortic valve. It also depicted the calcified raphe, more clear than that of transesophageal echocardiography.
