Abstract

We evaluated whether fluid status could be accurately assessed (and corrected if necessary) prior to right heart catheterisation (RHC), to diagnose accurately post-capillary pulmonary hypertension (PHT) in patients with left heart disease risk factors. A non-invasive measure of fluid status prior to RHC identified fluid-depleted patients. Baseline RHC measurements were performed, and a novel provocation technique (passive leg raise) was compared to a 'one-dose-fits-all' fluid challenge and found to be equivalent.

Keywords: left heart disease; pulmonary hypertension; right heart catheterisation.
