# Accuracy of site versus core laboratory interpretations of right heart catheterization hemodynamics

## TL;DR

This study compares how accurately different sites and a central lab interpret heart catheterization measurements for heart failure and lung pressure.

## Contribution

The study evaluates concordance and variability in RHC hemodynamic interpretations between sites and a core laboratory.

## Key findings

- Site and core laboratory interpretations of RHC hemodynamics showed variability.
- Concordance between site and core laboratory interpretations was evaluated for heart failure and pulmonary hypertension management.

## Abstract

An accurate interpretation of hemodynamics measured by right heart catheterization (RHC) is crucial for guiding the management of heart failure and pulmonary hypertension. We evaluated the concordance and variability between site-reported and core laboratory-adjudicated interpretations of invasive hemodynamic measurements.
