Number of attempts and interventions to obtain a valid pulmonary artery wedge pressure.

ABSTRACT:

Background

A valid pulmonary artery wedge pressure (PAWP) is essential for the hemodynamic characterization of pulmonary hypertension (PH). We prospectively investigated the methodology for obtaining a valid PAWP measurement, while assessing the impact of prespecified factors on its determination.

Methods

In this prospective observational cohort study, we included consecutive patients who underwent right heart catheterization (RHC) using fluoroscopy at the Pulmonary Vascular Disease program at Cleveland Clinic, between February and May 2023. Once a valid PAWP was obtained, we recorded the number of attempts, reason for repeating the determination, pulmonary artery location, depth of the pulmonary artery catheter (PAC) from the introducer hub, and inflation volume of the PAC
