CRT-500.11 Misclassification of Pulmonary Hypertension Due to Reliance on Pulmonary Capillary Wedge Pressure or Left Ventricular End-Diastolic Pressure Instead of Direct Mean Left Atrial Pressure

Abstract

Pulmonary arterial hypertension (PAH) is typically distinguished from pulmonary venous hypertension (PVH) by documenting a pulmonary capillary wedge pressure (PCWP) < 15 mm Hg. However, PCWP has uncertain utility in establishing PAH. Other suggests using left ventricular end-diastolic pressure (
