Pulmonary blood flow profiles with reduced right ventricular function in lambs

Abstract: The determinants of right ventricular (RV) performance with damaged RV free wall, such as occurs with RV infarction, are still unclear. Using 20-MHz Doppler ultrasound equipment, we investigated the changes in pulmonary blood flow velocity profiles before and after ligation of the right coronary artery. RV dp/dt, stroke volume, RV stroke work, aortic pressure and cardiac output decreased and central venous pressure rose after the ligation. The RV stroke work-end-diastolic pressure relationship indicated impair… Show more

“…10,12 Recently, experimental studies have reported the potential usefulness of the pulmonary flow patterns in the evaluation of right ventricular performance in the experimental RV infarction. 13 The goal of the study was to assess RV systolic performance in patients with inferior MI by means of Doppler echocardiography of pulmonary flow and to correlate them with hemodynamic findings.…”
