Lack of a Tricuspid Regurgitation Doppler Signal and Pulmonary Hypertension by Invasive Measurement.

ABSTRACT:

Background

Transthoracic echocardiography (TTE) is used to estimate pulmonary artery systolic pressure, but an adequate tricuspid regurgitation velocity (TRV) needed to calculate pulmonary artery systolic pressure is not always present. It is unknown whether the absence of a measurable TRV signifies normal pulmonary artery pressure.

Methods and results

We extracted hemodynamic, TTE, and clinical data from Vanderbilt's deidentified electronic medical record in all patients referred for right heart catheterization between 1998 and 2014. Pulmonary hypertension (PH) was defined as mean pulmonary artery pressure ≥25 mm Hg. We examined the prevalence and clinical correlates of PH in patients without a reported TRV. We identified 1262 patients with a TTE within 2 days of right hear
