简要总结

The VHD PV loop study intends to assess invasive right ventricular to pulmonary artery (RV-PA) coupling in patients with valvular heart disease (VHD). Invasive RV-PA coupling is measured by using conductance catheters, the gold standard assessment for ventricular physiology. Several non-invasive parameters have been reported as surrogates for this complex physiological entity, but none of them has been tested against the gold-standard in this population. Based on this, our main objective is to assess the correlation of imaging derived RV-PA coupling in comparison to the invasive measurement.

详细描述

This study aims to improve the assessment of right ventricular (RV) function in patients with valvular heart disease (VHD), by validating non-invasive imaging parameters of right ventricular to pulmonary artery (RV-PA) coupling against invasive measurements using conductance catheters-the gold standard for evaluating RV hemodynamics.

Currently available non-invasive tools do not always provide reliable evaluation of RV-PA coupling. This study seeks to identify accurate imaging surrogates to support clinical decision-making, particularly in conditions such as secondary mitral regurgitation, tricuspid regurgitation, and right-sided structural heart disease.

By correlating non-invasive indices-such as tricuspid annular plane systolic excursion to pulmonary artery systolic pressure ratio (TAPSE/PASP) and RV strain-with invasive data, the study may enhance diagnostic strategies, improve patient care, and support future prognostic and therapeutic investigations. Data may also contribute to post hoc analyses in existing registries and help refine our understanding of RV adaptation in structural heart disease.
