CONCLUSION
In this large single institution cross-sectional ECHO study, prevalence
of BAV was 0.51%. There was a high association with concomitant
ascending aortic aneurysm (40% of patients). 58% of patients at the
time of diagnosis of BAV were between 40 and 60 years of age. Incidence
of IE and severe AI in patients with BAV was significantly higher in
young age group, whereas severe aortic stenosis had a higher incidence
after age 40. Using multivariable logistic regression model, age and
increased BSA were identified as risk factors for aortic aneurysm
development.
