Valvular Heart Disease Registry Study in Second Affiliated Hospital of ZheJiang University

Summary

We design a prospective, observational cohort study to provide contemporary information on the prevalence, characteristics, risk stratification，cost-effective ,treatments and prognosis of Chinese hospitalised adult patients with valvular heart disease.

Eligibility

Inclusion Criteria:

Hospitalized patients over 18 years old meet one of the following conditions.
