Abstract: Transcatheter aortic valve replacement (TAVR) has changed the treatment of patients with severe aortic stenosis. However, the occurrence of conduction interference did not decrease significantly over time and it is still the main complication of the treatment. In addition, new onset atrial fibrillation was the most common tachyarrhythmia during hospitalization, which was associated with worse clinical outcomes. However, little is known about the incidence and clinical impact of arrhythmic events after perioperative TAVR. Recently, ambulatory electrocardiogram (AECG) monitoring has become a tool to solve the complex problem of arrhythmia (bradyarrhythmia and tachyarrhythmia) before and after TAVR. This review summarizes the status quo, clinical significance and future prospects of transcatheter aortic valve replacement (TAVR) in monitoring AECG in TAVR environment, which brings a new era for the treatment of aortic stenosis.
