Table 6. Diagnostic test performance of both apical and PLAX echo indices of RV function.

	Sensitivity	Specificity	PPV	NPV	Accuracy
TAPSE^*	76%	85%	73%	87%	82%
RV-S’^*	71%	81%	65%	83%	76%
FAC^*	65%	96%	89%	83%	85%
RV global longitudinal strain^**	85%	80%	71%	90%	82%
RV PLAX transverse strain^**	83%	79%	69%	89%	81%

* Tested using cutoffs included in consensus guidelines (TAPSE <1.6 cm; RV-S’<10 cm/sec; FAC<35%) [16]

**Tested using cutoffs (RV-GLS 18%, transverse strain 21%) derived from ROC analysis (Fig 6).
