Multicenter StudyNeed for permanent pacemaker as a complication of transcatheter aortic valve implantation and surgical aortic valve replacement in elderly patients with severe aortic stenosis and similar baseline electrocardiographic findings.
The aim of this study was to compare the incidence and predictive factors of complete atrioventricular block (AVB) and permanent pacemaker implantation (PPI) after transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement (SAVR). ⋯ Transcatheter aortic valve implantation was associated with a higher rate of complete AVB and PPI compared with SAVR in elderly patients with severe AS and similar baseline ECG findings. The presence of baseline right bundle branch block correlated with the need for PPI in the TAVI group.
