Overview
Study participants will be prospectively recruited from consecutive outpatient and inpatient populations presenting to the Cardiology and Cardiac Surgery Departments of the following participating institutions: The First Affiliated Hospital of Xi'an Jiaotong University, The Second Affiliated Hospital of Xi'an Jiaotong University, and \[add additional participating institutions as applicable\].
Interventions
- Diagnostic test Transthoracic Echocardiography
All patients in the case group undergo transthoracic echocardiography to assess valvular structure and function, which is the core diagnostic intervention for valvular lesions.
Primary outcome measures
- Diagnostic Accuracy (Sensitivity and Specificity) of the Novel Assay for Valvular Heart Disease [Time frame: Baseline (At the time of initial diagnostic testing)]
Eligibility criteria
Inclusion criteria
- \- Aged ≥ 18 years.
- For the case group: Presence of valvular lesions confirmed by transthoracic echocardiography.
- For the control group: Normal cardiac valves and no evidence of other cardiovascular diseases confirmed by transthoracic echocardiography.
- Ability to undergo and complete speckle tracking echocardiography.
Exclusion criteria
- Patients who are unwilling to participate in this study.
- Patients with a known allergy to the electrode patches or medical adhesive tapes used in this study.
- Patients who are unable to cooperate with the completion of required examinations.
- Patients with incomplete clinical or imaging data that cannot be supplemented.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
