Heart Valve Society Mitral and Tricuspid Valve Database

The Heart Valve Society (HVS) Mitral and Tricuspid Valve Database is an international, prospective, multicenter registry designed to monitor and improve care for patients with mitral and/or tricuspid valve disease. This collaborative initiative brings together expertise across cardiology, cardiac surgery, and cardiovascular research to support international standardization and improve lifelong outcomes for valve disease patients. The database captures detailed clinical, imaging, procedural, and patient-reported information on adult patients undergoing surgical or transcatheter interventions for valve stenosis, regurgitation, or prosthetic valve dysfunction.

The registry supports ambispective observational cohort studies and is open to centers performing mitral and/or tricuspid valve interventions. Participating centers may enroll patients consecutively or within project-based cohorts. Data elements include 293 baseline and case-mix variables, 78 clinical and imaging outcome measures, and two validated patient-reported outcome instruments (EQ-5D-5L and the Impact on Mental Health & Daily Activities questionnaire). Outcomes and definitions are harmonized with the International Consortium for Health Outcomes Measurement (ICHOM) heart valve disease standard set.

Controllership is regulated through a Joint Data Registry Agreement, under which all participating centers are joint controllers.The system complies with GDPR and HIPAA requirements, ensuring patient privacy through pseudonymized and anonymized data extracts.

Researchers can request access to multicenter data by submitting a research or project proposal. Users may work with data already available in the registry or initiate project-based data collection by defining a specific patient population and timeframe. After review and approval by the Scientific Committee, researchers receive a double-pseudonymized dataset suitable for analysis.
