Update in Heart Rhythm Abnormalities and Indications for Pacemaker After Transcatheter Aortic Valve Implantation
Objective: Rhythm abnormalities following transcatheter aortic valve implantation (TAVI)
and indications for permanent pacemaker implantation (PPI) were reviewed,
which aren't well established in the current guidelines. New left bundle
branch block and atrioventricular block are the most common
electrocardiographic changes after TAVI. PPI incidence ranges from 9-42% for
self-expandable and 2.5-11.5% for balloon expandable devices. Not only
anatomical variations in conduction system have an important role in
conduction disorders, but different valve characteristics and their
relationship with cardiac structures as well. Previous r ...
