Brief summary

This is a observational、multicenter, prospective cohort study for adults with significant VHD. The purposes of this study were to evaluate the etiology、clinical characteristics、treatment modalities, and outcomes of patients with VHD;also to set up registration system of adult VHD in China, to build a database of Chinese adult VHD, to establish a web-based international standard data acquisition system for VHD and a multicenter clinical research platform. The results of the study will provide a basis for the future national health policy for prevention and treatment of adult VHD.
