Conclusions
RV dysfunction is relatively common in patients with severe and critically severe COVID-19 pneumonia, which is related to the severity of illness. Early monitoring of RV function is very important for these patients. It is suggested that bedside echocardiography might be used as an objective examination in the evaluation of RV function in the COVID-19 pneumonia patients with ARDS. TAPSE may serve as a quantitative indicator of early detection of RV dysfunction. These findings are helpful to further improve the clinical diagnosis and treatment strategies for patients with COVID-19 pneumonia.
