Echocardiography of right ventricular-arterial coupling predicts survival of elderly patients with heart failure and reduced to mid-range ejection fraction
{{output}}
Echocardiography of right ventricular (RV)-arterial coupling obtained by the estimation of the ratio of the longitudinal annular systolic excursion of the tricuspid annular plane and pulmonary artery systolic pressure (TAPSE/PASP) has been found to be a remark... ...
