Supports TDE-Tei as potential non-invasive LV marker; leaves open prospective validation before clinical adoption.
Does the Tei index obtained from tissue Doppler echocardiography correlate with invasive measurements of left ventricular performance?
The TDE-Tei index correlates significantly with invasive measures of LV systolic and diastolic function, suggesting it is a feasible non-invasive indicator of overall LV performance.
Su et al. (2007) studied this question.
