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.
