A Multicenter Study on the Normal Reference Range and Clinical Significance of the Right Atrioventricular Coupling Index Assessed by Artificial Intelligence-Based Three-Dimensional Echocardiography

Korábbi kezelés

• Concurrent liver or renal disease
• Concurrent malignancy

Más betegség

• Clinically significant cardiac valve regurgitation (≥ mild severity)
• Respiratory diseases: acute or chronic respiratory disorders
• Endocrine diseases: thyroid disease, diabetes mellitus, hyperaldosteronism, pheochromocytoma, etc.
• Other systemic diseases: anemia, malignancy, connective tissue disease, large artery/peripheral vascular diseases (aortic dilation, aortic dissection, coarctation of the aorta, Takayasu arteritis, atherosclerosis), etc.
• Poor-quality ultrasound images that cannot support parameter measurement and analysis
  • Pulmonary Hypertension Group
• Unable to complete right heart catheterization or pressure-volume loop assessment
• Pericardial disease or arrhythmias (e.g., atrial fibrillation) that severely impair right heart function evaluation
• History of surgical procedures such as pulmonary endarterectomy or balloon pulmonary angioplasty
  • Heart Failure Group
• 1.Complicated with significant valvular heart disease (e.g., severe mitral regurgitation, severe tricuspid regurgitation, etc.)
• Pericardial disease or arrhythmias (persistent atrial fibrillation) that interfere with measurements
• Congenital heart disease or residual lesions after surgical correction
  • Atrial Septal Defect Group
• 1.Complicated with other complex congenital heart diseases.

Laborértékek

• Abnormal liver function (alanine transaminase > 2× upper limit of normal), abnormal renal function (elevated creatinine beyond normal range), or dyslipidemia (elevated triglycerides, total cholesterol, low-density lipoprotein, or high-density lipoprotein)
• Complicated with significant left heart disease (left ventricular ejection fraction [LVEF] < 50%, significant mitral valve disease)
