Usefulness of Right Ventricular Longitudinal Shortening Fraction to Detect Right Ventricular Dysfunction in Acute Cor Pulmonale Related to COVID-19
RIGHT VENTRICULAR (RV) dysfunction, evaluated by echocardiography, is not a rare complication of coronavirus disease 2019 (COVID-19) infection, with an estimated incidence of 27%.1 RV systolic function is classically assessed with transthoracic echocardiography (TTE) by RV-fractional area change (RV-FAC), tricuspid annular plane systolic excursion (TAPSE), or S′ tricuspid systolic (RV-S′) wave velocity obtained by tissue-Doppler imaging.2 More recently, two-dimensional speckle-tracking echocardiography (2D-STE), a semi-automated angle-independent method, has been developed to evaluate the RV systolic function.
