Poor Tricuspid Regurgitation Signal on Echocardiogram: How Does It Correlate with Pulmonary Artery Pressure as Measured by Right Heart Catheterization?
Year: 2021
Type: preprint
Study design: Observational Study
Abstract: BackgroundTricuspid Regurgitation (TR) gradient on echocardiogram is used to approximate pulmonary artery pressure (PAP) on echocardiography. A common dilemma is encountered when PAP measurement is indeterminate due to poor TR signal. We hypothesized that patients with poor TR signal would be unlikely to have pulmonary hypertension (PH) on right heart catheterization (RHC). MethodsWe performed a retrospective analysis of 141 patients who underwent RHC and had a corresponding echocardiogram showing poor TR signal within 2 months of RHC. A cutoff of 25 mm Hg was used as the upper limit of normal to define PH. ResultsFifty percent of patients had mean PAP (mPAP) greater than 25 mm Hg. 82% of values were 35 mm Hg or below. ConclusionsPoor TR signal does not rule out PH but may indicate lower likelihood of severe PH.
