Resting pump optimisation
Before optimisation | After optimisation | P value | |
AVO ratio, median (IQR), % | 100 (67–100) | 33 (25–50) | 0.001 |
Speed, mean (SD), RPM | 2690.9 (217.1) | 2855.5 (239.4) | <0.001 |
Power, mean (SD), W | 4.7 (1.2) | 5.5 (1.5) | 0.015 |
Flow, mean (SD), L/min | 4.4 (0.6) | 5 (1) | 0.028 |
Indexed flow, median (IQR), L/min/m2 | 2.1 (1.9–2.4) | 2.4 (2.1–2.8) | 0.038 |
Continuous variables are represented as mean (SD) and median (IQR); p values are from paired samples t-test (normal distribution) and Wilcoxon signed-rank test (non-normal distribution).
AVO, aortic valve opening; IQR, interquartile range ; RPM, revolutions per minute; SD, standard deviation.
