Effect of IFC Position on Outcomes
Table S3 gives univariate logistic regression results for the influence
of IFC position on PT/eCVA and freedom from HFRAs, as well as the Cox
proportional hazards regression for survival free from surgical
intervention for LVAD dysfunction. Prevalence of each outcome is given
for reference.
Readmission data were available for 102 patients. Twenty percent had
30-day HFRAs, and 70% experienced one or more HFRAs during the
follow-up period. There were significant relationships between IFC
position and readmissions (Figure 7). A negative anterior plane angle
predicted increased overall HFRAs (p = 0.01), with an odds ratio of 3.35
for an angle ≤ -20 deg (p = 0.01). Increasing total malposition
magnitude predicted increased 30-day HFRAs (p = 0.04), with an odds
ratio of 3.65 for a deviation ≥ 40 deg (p = 0.02).
Twenty-two percent of patients experienced PT/eCVA. There was no
relationship between IFC position and PT/eCVA. There was also no
influence of IFC position on survival free of reoperation for LVAD
dysfunction.
