Figures
- Figure 1. The angle of the inflow cannula (AIC) as measured on routine chest x-ray demonstrates (A) a normal left ventricular assist device (LVAD) cannula position and angle and (B) an abnormal LVAD cannula position and angle in a patient who required device exchange.
- Figure 2. Comparison of the median angle of the inflow cannula (AIC) for the entire cohort, the control group, and the pump thrombosis (PT) group.
aIntergroup (unpaired) comparison P values.
bIntragroup (paired) comparison P values.
- Figure 3. Box and whisker plots comparing the median angle of the inflow cannula (AIC) for the control group and the pump thrombosis (PT) group at implant and follow-up. For each group, the thick black line denotes the median, the upper and lower limits of the box denote the first and third quartile, and the bars denote maximum and minimum values.
