Abstract

Doppler-derived ratio of peak tricuspid regurgitant velocity (TRV, ms) to the right ventricular outflow tract time velocity integral (TVIRVOT, cm) is a reliable non-invasive method of estimating pulmonary vascular resistance (PVR). The easier to measure left ventricular outflow tract time velocity integral (TVILVOT, cm) has been presented as an alternative to TVIRVOT in patients with severe pulmonary hypertension. The correlation of TRV/TVILVOT with PVR in other populations has not been reported.
