Impact of Changes in Left Ventricular Ejection Fraction on Survival After Transapical Aortic Valve Implantation

LVEF worsened in a small number of patients after transapical transcatheter aortic valve implantation, but this change was not associated with worse postoperative outcomes. Patients with a low LVEF showed better improvement. The progressive reduction of sheath diameter does not have a significant effect on LVEF changes.
