Transcatheter aortic valve replacement (TAVR) has changed the treatment
of patients with severe aortic stenosis. However, the occurrence of
conduction disturbances has not decreased significantly over time and
remains the main drawback of the procedure. In addition, new-onset
atrial fibrillation is the most frequent tachyarrhythmia during the
hospitalization period and is associated with worse clinical outcomes.
However, little is known regarding the incidence and clinical impact of
arrhythmic events beyond the periprocedural TAVR period. Ambulatory
electrocardiogram (AECG) monitoring has recently emerged as a tool to
unravel the complex issue of arrhythmic disorders (bradyarrhythmias and
tachyarrhythmias) before and after TAVR. To date, the preliminary
results from the initial experience using AECG monitoring systems showed
the safety, usefulness, and potential clinical implications of this
diagnostic tool in TAVR recipients. This review provides an overview of
the current status, clinical implications, and future perspectives of
AECG monitoring in the TAVR setting.
