Doppler estimation of pulmonary artery systolic pressure (PASP) from tricuspid regurgitation velocity is a simple approach to the detection of pulmonary hypertension but may be influenced by right ventricular stroke volume. We sought the clinical utility of incorporating Doppler calculation of pulmonary vascular resistance (PVR) into determination of pulmonary hypertension in 578 consecutive patients with tricuspid regurgitation. Right atrial pressure was estimated from vena caval dimensions… CONTINUE READING
