Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
