What are the main factors influencing the accuracy of regional longitudinal peak systolic strain in transthoracic echocardiography automatic functional imaging?
p-value: p=<0.05
The accuracy of regional longitudinal peak systolic strain in automatic functional imaging is significantly affected by operational factors such as ROI, aortic valve closure time, and frame rate.
Li et al. (2018) conducted an observational in Healthy volunteers (n=82). Transthoracic echocardiography real-time tri-axial automatic functional imaging (AFI) was evaluated on Success rate of AFI and differences in regional longitudinal peak systolic strain (RLS) by different operations (p=<0.05). Transthoracic echocardiography real-time tri-axial automatic functional imaging had a 74% success rate, with regional longitudinal peak systolic strain significantly influenced by operational factors (P<0.05).
