Right ventricular–pulmonary arterial coupling and its relationship to exercise haemodynamics in a continuum of patients with pulmonary vascular disease due to chronic thromboembolism

This retrospective study shows that TAPSE/sPAP ratio, a simple surrogate of RV–PA coupling, may help to identify patients with PVD due to chronic thromboembolism and predicts impaired pulmonary exercise haemodynamicshttps://bit.ly/3osXxzV
