From: Stroke volume variation remains accurate in the presence of proximal stenosis
Changes in hemodynamic indicators over time. The data obtained from arterial pressure lines inserted into the right radial artery (healthy side) and the left radial artery (with proximal artery stenosis) were shown. The left radial artery pressure was about 50 mmHg lower than the right radial one. The pressure gradient was constant throughout, suggesting the presence of a substrate proximal stenosis. The cardiac output was also different between left and right, but both increased with infusion load. Left and right SVV remained almost constant, responding similarly to infusion load
