A novel echocardiographic predictor of in-hospital mortality and mid-term haemodynamic improvement after pulmonary endarterectomy for chronic thrombo-embolic pulmonary hypertension

Abstract

NR is related with in-hospital mortality and residual pulmonary hypertension after PEA. NR > 1.0 is associated with a higher risk of such unfavourable outcomes. NR may be considered a determinant of eligibility for PEA.
