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.
