Background: Transcatheter aortic valve replacement (TAVR) is an
effective alternative treatment for patients with aortic stenosis (AS) who have
intermediate to high surgical risk or who are inoperable. However, the incidence
of conduction abnormalities is high after TAVR, which can reduce the
effectiveness of the surgery. Our research objective is to explore the risk
factors of new-onset conduction abnormalities after TAVR, providing reference
value for clinical doctors to better prevent and treat conduction abnormalities.
Methods: Patients who underwent TAVR were divided into those who
developed heart block and those who did not. Baseline clinical characteristics,
cardiac structural parameters, procedural characteristics, electrocardiogram (ECG) changes before and
after TAVR (
