Prospective Cohort Study on Imaging Genetics of Bicuspid Aortic Valve

The Chinese Bicuspid Aortic Valve (BAV) Ultrasound imaging cohort study is a Chinese BAV ultrasound imaging cohort study. At present, a retrospective study cohort involving more than 30 hospitals has been established. The prospective multi-center study of BAV is expected to include and follow up 200 outpatients and inpatients with BAV. The clinical, ultrasound imaging and treatment parameters of the patients are collected and the patients are followed up for 2 years. To analyze the prognostic characteristics of BAV patients and establish a Chinese BAV database. The primary endpoint was all-cause death, and the secondary endpoints were heart failure, angina, severe aortic stenosis, severe aortic insufficiency, ascending aortic diameter ≥50mm, and surgery (surgical and interventional). According to the different pathological types of aortic valve in different types of BAV, ultrasound imaging was used to evaluate the different forms of valvular leaflet lesions and prognosis. Finally, it provides a basis for the prognosis, treatment method, treatment timing and treatment plan selection of BAV patients, and lays a foundation for the mechanism study of BAV arterial lesions and the establishment of risk model for the prognosis of BAV patients.
