95933-8
ClinicalTranspulmonary pressure gradient
Definition
Transpulmonary pressure gradient (TPG) is the difference between the mean pulmonary arterial pressure and left atrial pressure, which may be approximated by the pulmonary capillary wedge pressure; it can be used to identify intrinsic pulmonary vascular disease in left-heart conditions with correlated increased pulmonary venous pressure.
