Left Ventricular Global Systolic Longitudinal Deformation and Prognosis 1 Year after Femoral and Apical Transcatheter Aortic Valve Implantation

LV EF and longitudinal systolic deformation were improved in TAVI independent of technical approach using the Edwards SAPIEN valve prosthesis during 1-year follow-up. The mortality rate was comparable between technical approaches and independent of baseline LV function. However, patients with the greatest improvement in LV systolic longitudinal deformation after TAVI had a lower mortality rate.
