Data are expressed as mean ± SD. mPAP = mean pulmonary arterial pressure; PAWP = pulmonary arterial wedge pressure; PVC = pulmonary vascular compliance; PVR = pulmonary vascular resistance; RAP = right atrial pressure; TPG = transpulmonary gradient; TPR = total pulmonary resistance; WU = Wood units.
