Résumé :

The development of right ventricular (RV) dysfunction in pulmonary hypertension (PH) patients is associated with adverse outcome, so that the assessment of RV function has become increasingly important in the management of such patients. The present objective was to test the hypothesis that RV free-wall longitudinal speckle-tracking strain (RV-free), an independent echocardiographic predictor of hemodynamic RV performance, can predict long-term outcome.
