Transcatheter aortic valve implantation (TAVI) has brought a new era in the treatment
of aortic stenosis. During the last years, the successive iterations of transcatheter
heart valve (THV) systems and the growing experience of centres/operators have translated
into a progressive reduction in periprocedural complications. However, conduction
disturbances, such as high-degree atrioventricular block and new-onset left bundle
branch block (LBBB), have not decreased over time and remain the most frequent drawback
of the procedure.
1
The incidence of new-onset LBBB with the use of newer-generation THVs has ranged
from 6% to 77%.
2
The use of different definitions of new-onset LBBB (mainly different time points),
along with differences in baseline and procedural characteristics (including valve
type, valve positioning), may explain this large variability in incidence.To read this article in full you will need to make a payment

- New-Onset Left Bundle Branch Block After TAVI has a Deleterious Impact on Left Ventricular Systolic FunctionCanadian Journal of CardiologyVol. 35Issue 10
- PreviewTranscatheter aortic valve implantation (TAVI) has revolutionized the management of severe aortic stenosis. The development of a new-onset complete left bundle branch block (LBBB) is, however, a frequent complication. The objective of the present study was to assess the impact of a new-onset LBBB after TAVI on the evolution of left ventricular ejection fraction (LVEF).
