About this trial
The objective of this study is to evaluate and predict the progression of moderate cardiac valve stenosis and regurgitation using clinical, biological, echocardiographic, computed tomography (CT), and magnetic resonance imaging (MRI) data. Additionally, the study aims to analyze the potential impact of device-based interventions, pharmacological therapy, and lifestyle modifications on disease progression.
Eligibility criteria
Qualifiers
At least 18 years old;
Be willing and able to provide informed consent to participate in the study;
Grade II or higher Aortic valve regurgitation: regurgitant jet width >3 mm, jet width / LVOT diameter ≥25%, jet cross-sectional area/LVOT cross-sectional area ≥5%, effective regurgitant orifice area (EROA) ≥0.1 cm², regurgitant volume per beat (R Vol)≥30 ml, or regurgitant fraction (RF) ≥30%.
Moderate or higher aortic valve stenosis: peak velocity ≥3.0 m/s, Mean gradient ≥20 mm Hg, aortic valve area ≤1.5 cm², Indexed aortic valve area ≤0.85 cm²/m², or velocity ratio ≤0.50.
Disqualifiers
Patients who are unwilling to accept registration and follow-up;
Patients who cannot cooperate with information collection and follow-up due to mental illness or other conditions;
Patients whose life expectancy is less than 12 months due to non-cardiac diseases (such as cancer, liver disease, kidney disease, or end-stage lung disease).
