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 a non-rare complication of 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.
