| heal.abstract | BACKGROUND: Pulmonary vascular resistance (PVR) is a critical parameter in the assessment and treatment of patients with pulmonary hypertension, regardless of origin. Noninvasive estimation of PVR could be helpful. METHODS: Consecutive patients with known or suggested pulmonary hypertension referred for cardiac catheterization were evaluated prospectively and the PVR was calculated invasively. Subsequently, the tricuspid regurgitation velocity (TRV), the velocity-time integral (mean of 3 measurements) of the right ventricular outflow tract (VTIm), and the right ventricular outflow tract diameter were recorded noninvasively. RESULTS: The TRV/VTIm ratio and the TRV/VTIm corrected for the indexed RVOT diameter correlated well with the PVR at catheterization with R(2) = 0.711 and R(2) = 0.731, respectively, including patients with very high values of PVR. A TRV/VTI(RVOT) value of 38 provided a specificity of 100% for a PVR of 8 Woods units. CONCLUSION: Noninvasive estimation is feasible over a broad range of PVR values and could be a useful tool to estimate and longitudinally tracked changes in PVR. | en |
