Almitrine for COVID-19 critically ill patients – a vascular therapy for a pulmonary vascular disease: Three case reports

Figure 1 Evolution of pulmonary artery catheter, respiratory and echocardiographic parameters with almitrine infusion. A: Pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) during almitrine infusion; B: PaO2/FiO2 ratio and total respiratory system compliance (CRS) during almitrine infusion; C: Right ventricular fractional area change (FAC) and right ventricular (RV) global longitudinal strain (RVGLS) remained unchanged for patient 1 and patient 2 and improved for patient 3. Tricuspid longitudinal annular displacement (TMAD) remained unchanged for the three patients.
