Abstract
This study demonstrated that the TDI-Tei index correlates well with the Tei index determined by pulsed Doppler, and thus represents a simple method of assessing RV myocardial performance. Moreover, the TDI-Tei index has the advantage of simultaneous recording of systolic and diastolic velocity patterns, suggesting that the TDI-Tei index is a feasible approach to assess global RV function in children.
