Tissue Doppler imaging offers non-invasive assessment of atrial function, crucial for the circulatory system. This review details methods, normal findings, and clinical uses in heart diseases like atrial fibrillation and heart failure.
Area of Science:
- Cardiology
- Physiology
Background:
- Atrial function is vital for overall circulatory system performance.
- Non-invasive echocardiography methods are increasingly used to evaluate atrial mechanics.
Purpose of the Study:
- To review methods for assessing regional atrial function using tissue Doppler imaging.
- To summarize normal findings and clinical applications in cardiac diseases.
Main Methods:
- Tissue Doppler imaging (TDI) velocity and strain imaging.
- Echocardiographic assessment of haemodynamic and mechanical characteristics.
Main Results:
- TDI provides detailed insights into atrial electromechanical function.
- Normal reference values for healthy subjects are established.
- Clinical utility demonstrated in atrial fibrillation, ischemic heart disease, and heart failure.
Conclusions:
- Tissue Doppler imaging is a valuable tool for evaluating atrial function.
- Understanding atrial function is key to managing various cardiac conditions.
