Integrating Right Ventricular Pressure Waveform Analysis With Two-Point Volume Measurement for Quantification of Systolic and Diastolic Function: Experimental Validation and Clinical Application

J Cardiothorac Vasc AnesthPublished Retrospective observational analysis

Authors' conclusion

Study results supported the possibility of integrating automated RV pressure analysis with RV volume measured by 3D echocardiography to create a comprehensive assessment of RV systolic and diastolic function at the bedside.

Study context

Population
Archived data from anesthetized swine and awake patients undergoing clinically-indicated right-heart catheterization
Exposure
Single-beat measures of right ventricular (RV) contractility and diastolic capacitance vs multi-beat, preload-variant reference standards
Outcome
Single-beat RV end-systolic elastance and V15 vs multi-beat reference standards (correlation, Bland-Altman, 4-quadrant concordance)
Methodological detailsexperimental validation, clinical application, University laboratory
  • Experimental validation
  • Clinical application
  • University laboratory

Main finding

As reported in the abstract

  • Methods not directly interchangeable with reference standards, but sufficiently robust to suggest potential clinical utility

Observational data: associations, not effects.

Further findings

Clinical application: response to inhaled nitric oxide during diagnostic right-heart catheterization

Enhanced assessment of the response to inhaled nitric oxide
