Why the study?
Definitive guidelines for managing cardiac conduction disorders following TAVI are not yet available, leaving treatment decisions to individual clinicians.
TAVI is associated with a significant risk of conduction abnormalities requiring permanent pacemaker implantation, highlighting the need for standardized management guidelines.
Degenerative aortic stenosis is an inflammatory process, affecting up to 12% of patients aged over 85 years. Transcatheter aortic valve implantation (TAVI) has become the preferred option for symptomatic, high and intermediate risk patients, including those denied for surgical valve replacement. Aortic stenosis is associated with prolonged atrio-ventricular (AV) conduction time, as well as higher degree of AV conduction disorders. In addition, it was observed that TAVI patients have a higher incidence of conduction abnormalities during the procedure, as well as during the following days, many of them requiring the implantation of a permanent pacemaker. Definitive guidelines for management of the conduction disorders are not yet available, the burden of choosing the best approach being put on each individual clinician.
