Inclusion criteria
Inclusion criteria: 1. Diagnosed by echocardiography with moderate or greater tricuspid regurgitation (TR) (according to the American Society of Echocardiography guidelines: effective regurgitant orifice area >= 40 mm^2 or regurgitant volume >= 45 mL); 2. Aged between 18 and 80 years, of any gender; 3. Clear transthoracic echocardiographic images that meet the requirements for speckle tracking echocardiography (STE) analysis (right ventricular free wall clearly visible, frame rate >= 50 frames/second); 4. Voluntarily willing to participate in this study and sign the informed consent form.
Exclusion criteria
Exclusion criteria: 1. Primary cardiomyopathies (such as hypertrophic cardiomyopathy, dilated cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, etc.); 2. Congenital heart disease (such as Ebstein's anomaly, Tetralogy of Fallot, etc.); 3. Acute myocardial infarction or unstable angina within the past 3 months; 4. Moderate or more severe left heart valvular disease (such as aortic stenosis/insufficiency, mitral stenosis/insufficiency); 5. Persistent atrial fibrillation or other serious arrhythmias (affecting the accuracy of STE image analysis); 6. Severe hepatic or renal insufficiency (Child-Pugh class C or eGFR < 30 mL/min/1.73m²); 7. Pregnant or breastfeeding women; 8. Poor ultrasound image quality, unable to meet STE analysis requirements; 9. Expected poor compliance, unable to complete follow-up.
