Of 384 patients without baseline aneurysms, 49 developed aneurysms at follow-up,
incidence of 84.9 (95% CI, 63.3-110.9) cases per 10 000 patient-years and an age-adjusted relative risk 86.2 (95% CI, 65.1-114; P <.001 compared with the general population).
The 25-year rate of aortic surgery was 25% (95% CI, 17.2%-32.8%).

Conclusions In the population of patients with BAV, the incidence of aortic dissection over a mean of 16 years of follow-up was low but significantly higher than in the general population.
