Exposure
Two-dimensional speckle-tracking echocardiography (2D STE) for measuring left ventricular twist
Two-dimensional speckle-tracking echocardiography is a clinically applicable and valid method for evaluating left ventricular twist mechanics, which are altered in various cardiomyopathies.
Limitations
- STE is an offline technique requiring earlier acquired 2D images
- Low frame rates cause loss of speckles, while high frame rates depress spatial resolution and image quality
- Requires ECG gating with minimal heart rate variability
