Dilation of the ascending aorta (AA), which is disproportionate to associated vaivular lesions, is a relatively well-recognized phenomenon in patients with a bicuspid aortic valve (BAV).

Baseline diameters at the sinuses of Valsalva (SV), the sinotubular junction (STJ), and the tubular tract (TT) were similar in both groups (41.3 +/- 5.3 vs 42.3 +/- 6.3 mm, p = NS, 37.8 +/- 5.2 vs 38.7 +/- 5.5 mm, p = NS. and 47.3 +/- 5.3 vs 45.9 +/- 5.1, p = NS, respectively). During an average 3-year follow-up, the rate of AA diameter progression was similar for the BAV and TAV groups (0.86 +/- 0.81 vs 0.82 +/- 1.1 mm/year, p = NS for the SV; 1.06 +/- 1.6 vs 0.63 +/- 1.1 mm/year, p = NS for the STJ: and 0.81 +/- 1.1 vs 0.75 +/- 1.1 mm/year, p = NS for the TT, respectively).

Abstract

Dilation of the ascending aorta (AA), which is disproportionate to associated vaivular lesions, is a relatively well-recognized phenomenon in patients with a bicuspid aortic valve (BAV). The aim of this study was to evaluate the rate of changes in the AA dimensions and the outcome in patients with AA dilation and BAN's compared with patients with AA dilation and tricuspid aortic valves (TAVs). Serial transesophageal echocardiograms (> 12 months apart) were performed in 113 consecutive patients (BAV, n = 27 and TAV, n = 86) with AA diameters of 40 and :560 mm, respectively, without associated significant aortic valve stenosis or regurgitation. Baseline diameters at the sinuses of Valsalva (SV), the sinotubular junction (STJ), and the tubular tract (TT) were similar in both groups (41.3 +/- 5.3 vs 42.3 +/- 6.3 mm, p = NS, 37.8 +/- 5.2 vs 38.7 +/- 5.5 mm, p = NS. and 47.3 +/- 5.3 vs 45.9 +/- 5.1, p = NS, respectively). During an average 3-year follow-up, the rate of AA diameter progression was similar for the BAV and TAV groups (0.86 +/- 0.81 vs 0.82 +/- 1.1 mm/year, p = NS for the SV; 1.06 +/- 1.6 vs 0.63 +/- 1.1 mm/year, p = NS for the STJ: and 0.81 +/- 1.1 vs 0.75 +/- 1.1 mm/year, p = NS for the TT, respectively). Three patients in the TAV group experienced cardiac death (2 died suddenly and 1 after emergency surgery for AA dissection); there was no occurrence of cardiac death in the BAV group. In conclusion, the rate of progression of AA aneurysms was similar in patients with BAVs and in those with TAVs. Furthermore, patients with BAVs did not have increased rates of AA related complications compared with patients with TAVs. (c) 2006 Elsevier Inc. All rights reserved.
