The EVIDENTIA Registry is a multicenter study designed to evaluate valvular heart disease (VHD) using cardiac CT. It aims to assess cardiac valve anatomy, function, and myocardial characteristics through detailed CT analysis.

1. Assessing the accuracy of cardiac CT in evaluating cardiac structure, volume, function, and myocardium in VHD patients.
2. Comparing the severity, classification, and etiology (primary vs. functional) of VHD.
3. Monitoring serial changes in VHD severity via echocardiography.
4. Investigating the relationship between echocardiographic and CT-derived parameters.
5. Examining the correlation between imaging findings, VHD interventions, and patient prognosis.

Inclusion Criteria:

• Patients with at least moderate valvular heart disease who had a cardiac CT with 64 or more rows
• 18 years of age or older

Exclusion Criteria:

• Less than 18 years old
• Acute VHD
• Infectious endocarditis
• Patients with post-VHD intervention
• Poor CT image quality for analyzing CT data.

The study will be conducted at 7 centers throughout Japan, with the goal of enrolling a total of approximately 300-350 cases.
