Echocardiographic findings in patients with aortitis syndrome.

Echocardiography was performed in 18 patients with the aortitis syndrome and in 20 age-matched normal volunteers. The aortic root dimension, the aortic dimension at the level of the sinotubular ridge, the aortic arch dimension, the left ventricular internal dimension, the left atrial dimension, the interventricular septal thickness, and the left ventricular posterior wall thickness were measured. All measurements, except for the left atrial dimension, were significantly greater in patients with aortitis syndrome than in the control subjects. We concluded (1) that the patients with the aortitis syndrome may have an enlarged or narrowed aorta, a dilated left ventricle and left atrium, and a thickened interventricular septum and left ventricular posterior wall; (2) that the incidence and the degree of these abnormalities depend on the presence of complications such as aortic regurgitation and arterial hypertension; and (3) that M-mode as well a cross-sectional echocardiography plays an important role in the assessment of the aorta and heart in the aortitis syndrome.
