CONCLUSIONS
In this study, we extended our prior work on IFC
malposition1,3 by assessing the effect of preoperative
anatomic and surgical technique on CF-LVAD IFC malposition, and the
effects of malposition on LV unloading and outcomes. We found that the
LTHS technique was associated with a lower total malposition magnitude,
and that a more laterally and posteriorly displaced apex and a more
steeply inclined apex-LVOT axis portend malposition. Post-LVAD, we found
that IFC malposition was associated with lower LVAD FI and with
increased 30-day and overall HFRAs. Careful surgical planning and
attention to intraoperative IFC positioning may mitigate these risks.
Further study in a large, multicenter cohort is warranted.
