Fig. 5From: Deformation pattern and predictive value of right ventricular longitudinal strain in children with pulmonary arterial hypertensionReceiver-operator characteristic analysis. The optimum cut-off value for Mid RV free wall LpsS to predict clinical worsening was −18.50 %; the sensitivity and specificity were 91.7 and 30.8 %. The area under curve was 0.88 ± 0.06 (95 % CI: 0.75–1.00, p = 0.001)Back to article page
