To investigate the right heart function in coronavirus disease 2019 (COVID-19)
patients with acute respiratory distress syndrome (ARDS), a retrospective
analysis of 49 COVID-19 patients with ARDS was performed. Patients were divided
into severe group and critically-severe group according to the severity of
illness. Age-matched healthy volunteers were recruited as a control group. The
cardiac cavity diameters, tricuspid annular plane systolic excursion (TAPSE),
tricuspid valve regurgitation pressure gradient biggest (TRPG), pulmonary
arterial systolic pressure (PASP), maximum inferior vena cava diameter (IVCmax)
and minimum diameter (IVCmin), and inferior vena cava collapse index (ICV-CI)
were measured using echocardiography. We found that the TAPSE was significantly
decreased in pneumonia patients compared to healthy subjects (P
