[Thoracic aorta echocardiographic features of patients with bicuspid aortic valve].

Objective: To observe the thoracic aorta features in patients with bicuspid aortic valve (BAV) with echocardiography.

Methods: We retrospectively analyzed the echocardiographic features and clinical manifestations in 273 patients with BAV detected from 1991-04 to 2006-02.

Results: (1) Aortic dimensions of the anulus, the sinuses of valsalva, the sinotubular junction, the ascending aorta at the level of its largest diameter of 31 patients with functionally normal BAV were significantly increased compared that in control subjects (P < 0.
