Methods

All consecutive patients, observed from 1992 to 2003, with dilation (diameter ≥40 mm) of ≥1 segment of the proximal thoracic aorta at transthoracic echocardiography, a finding that was confirmed with a transesophageal study, and with normal aortic valvular function were included in the study.

Results

The study population consisted of 113 patients with ≥2 serial transesophageal echocardiograms. For patients had >2 transesophageal echocardiograms, the latest echocardiogram was used in the estimation of the AA progression rate.

Discussion

To our knowledge, this is the first prospective study to compare the rate of progression for AA aneurysms between patients with normally functioning BAVs and TAVs. Our main finding is that the rate of progression of AA dilation is similar between patients with BAVs and patients with TAVs.
