due the positive intra-thoracic pressure. Also, in this situation, the RV afterload increases, secondary to the increase of the trans-pulmonary pressure and of the pulmonary vascular resistance and the vasoconstriction related to hypoxemia and hypercapnia (4) . The onset of RV dysfunction and RV dilation (figure 1) may also affect the left ventricular function and loading. This is explained by ventricular interdependence and paradoxical septum. In this case, a reduced cardiac output occurs, depressing the systemic perfusion and exposing the patient to RV ischemia. In addition, COVID-19 patients disclose a hyper coagulate state avec a significant incidence of pulmonary thrombotic complications, aggravated the RV afterload is associated with excess mortality in ARDS (4). The ACP is classically associated with the following parameters: the driving pressure, the PaCO2 and the PaO2/FiO2 ratio (4). Finally, the RV function, measured by the tricuspid annular plane systolic excursion (TAPSE), the right ventricular fractional area change (RVFAC) and the right ventricular longitudinal strain, is a significant predictive factor of mortality in COVID-19 infected patients (6) . In this context, in addition with the left ventricular function analysis, it is of importance to check and assess the right ventricle in COVD-19 infected patients, particularly in critical situation.
