1. An algorithm for investigating pulmonary hypertension (PH) using echocardiography.
An algorithm for investigating pulmonary hypertension (PH) using echocardiography. TRV: tricuspid regurgitant velocity; PRV: pulmonary regurgitant velocity; RV: right ventricle; LV left ventricle; PLAX: parasternal long axis; RVOT: right ventricular outflow tract; AT: acceleration time; TAPSE: tricuspid annular plane systolic excursion; IVRT: isovolumic relaxation time; IVC: inferior vena cava; RA: right atrium. #: in patients >60 yrs of age, a TRV ≥2.9 m·s−1 is used as a cut-off value [13].
