Severe forms of COVID-19 infection are associated with the need for invasive mechanical ventilation and thromboembolic complications; those can affect the cardiac function especially the right ventricle performance. Critical care echocardiography has rapidly evolved as the election technique in the evaluation of the critically ill patients. This technique has the advantage that it can be done at patient´s bedside and helps to provide the appropriate treatment and to monitoring maneuver's response. We present 4 patients with a confirmed COVID-19 infection who presented with sudden hemodynamic and / or respiratory deterioration, in which transthoracic echocardiogram showed acute right ventricular failure as the trigger for the event and helped to guide an early therapeutic intervention. <Learning objective: Routine echocardiographic evaluation must be mandatory in patients with COVID-19 infection. The presence of refractory hypoxemia and/or hypotension should raise the suspicion of right ventricle failure and must be evaluated with transthoracic echocardiogram. In the clinical scenario of acute right ventricular failure, rising D-dimer and suspected pulmonary embolism, thrombolysis must be considered even without tomographic confirmation.>.
