Key messages Increased pulmonary vascular resistance and RA-PA uncoupling is present in a significant subset of patients with sepsis, and measurement with TTE is feasible. Measurement of PAAT and RV-PA uncoupling could aid in improving definitions of right ventricular dysfunction. The therapeutic and prognostic role of these parameters in sepsis remains unknown, and further prospective studies are warranted.
