Features Associated With Discordance Between Pulmonary Arterial Wedge Pressure and Left Ventricular End Diastolic Pressure in Clinical Practice: Implications for Pulmonary Hypertension Classification. Chest. 2018 Nov;154(154). 1099-1107. PMID: 30148982 [PubMed] PMCID: PMC6224703
The measurements used to define pulmonary hypertension (PH) etiology, pulmonary arterial wedge pressure (PAWP), and left ventricular end-diastolic pressure (LVEDP) vary in clinical practice. We aimed to identify clinical features associated with measurement discrepancy between PAWP and LVEDP in patients with PH.
