Does volumetric pulmonary artery catheter accurately measure right ventricular volumes and ejection fraction compared to conductance catheter during acute right ventricular ischemia?
Absolute Event Rate: 0.76% vs 0.98%
Volumetric pulmonary artery catheters have low accuracy for measuring right ventricular ejection fraction and end-diastolic volume during acute right ventricular ischemia compared to conductance catheters.
Hein et al. (2009) studied Right ventricular ischemia (n=7). Volumetric pulmonary artery catheter vs. Conductance catheter was evaluated on Diagnostic accuracy (area under the curve) to detect ischemia using right ventricular ejection fraction. Volumetric pulmonary artery catheter had low diagnostic accuracy for detecting right ventricular ischemia compared to conductance catheter (AUC for ejection fraction 0.76 vs 0.98).
