Fig. 3From: Energetic performance index improvement after Glenn and Damus-Kaye-Stansel procedure using vector flow mapping analysis: a case reportFlow energy loss (top) and flow kinetic energy (bottom) during one cardiac cycle. Upper graph demonstrates the pattern of flow energy loss during one cardiac cycle. The blue line presents preoperative energy loss, and the yellow line represents postoperative energy loss. Lower graph demonstrates the pattern of flow kinetic energy of the left ventricle during one cardiac cycle. The red line presents preoperative kinetic energy, and the purple line represents postoperative energy lossBack to article page
