Sinotubular Ridge

The sinotubular ridge the portion of the ascending aorta just distal to the sinuses of Valsalva at the junction with the tubular segment of the ascending aorta.

Dilation of the aortic valve and effacement of the sinotubular ridge is characteristic of Marfan syndrome and other connective disorders, while one of the characteristic features of syphilitic aneurysm is sparing of the sinotubular junction

Aortic sinotubular ridge calcification may be associated with coronary artery disease.
