Feasibility of Right Ventricular Longitudinal Systolic Function Evaluation with Transthoracic Echocardiographic Indices Derived from Tricuspid Annular Motion: A Preliminary Study in Acute Respiratory Distress Syndrome

Abstract

Despite a superior feasibility than 2D study, our results suggest that both indices may not bring identical information to echo study. TAPSE may be more adapted to ICU use than S(t) . Both should be further investigated in terms of analysis of RV function and ventricular interdependence. Their relations with LV function may limit their use as sole markers of RV function in this population.
