Bicuspid Aortic Valve, Echocardiography, Long-term progress

Bicuspid Aortic Valve (BAV) is a common congenital heart disease with an incidence ranging from 0.16% in Asians to 2% in Westerners. Asian populations with BAV have different morphological characteristics from those of the Western populations, and further elucidation of these differences will serve as a guide for the treatment and follow-up of Asian patients. Therefore, we conducted this multicentre retrospective study to analysis the clinical features, long-term development and surgical prognosis of BAV .

Bicuspid Aortic Valve (BAV) is a common congenital heart disease with an incidence ranging from 0.16% in Asians to 2% in Westerners, and more than one half of patients require medical or surgical treatment within 20 years of diagnosis. Therefore, early diagnosis and effective treatment can help to reduce the incidence of irreversible cardiac impairment and adverse outcomes such as sudden death. Asian populations with BAV have morphological characteristics that differ from those of the Western populations, and further elucidation of these differences could serve as a guide for the treatment and follow-up of Chinese patients. Based on the above background, We conducted this multicentre retrospective study. We will search for patients diagnosed with BAV by echocardiography or other imaging examinations from December 2021 to October 2022 at Nanjing Gulou Hospital, Jiangsu Provincial Hospital and Nanjing Children's Hospital; collect clinical symptoms, signs and examination results of them; find out the specific surgical plan and time of surgery if they have undergone surgery; follow up for symptoms, medication and reexamin Echocardiography to confirm any endpoint events.
