Value of Periprocedural Electrophysiology Testing During Transcatheter Aortic Valve Replacement for Risk Stratification of Patients With New-Onset Left Bundle-Branch Block.

Background Despite being the most frequent complication following transcatheter aortic valve replacement (TAVR), optimal management of left bundle-branch block (LBBB) remains unknown. Electrophysiology study has been proposed for risk stratification. However, the optimal timing of electrophysiology study remains unknown.

Non-invasive predictors for infranodal conduction delay in patients with left bundle branch block after TAVR.

Aims: Left bundle branch block (LBBB) is the most common conduction disorder after transcatheter aortic valve replacement (TAVR) with an increased risk of atrioventricular (AV) block. The aim of the current study was to identify non-invasive predictors for infranodal conduction delay in patients with LBBB.

Methods: We analyzed consecutive patients undergoing TAVR with pre-existing or new-onset LBBB between August 2014 and August 2020.

Incidence and predictors of atrial fibrillation progression: A systematic review and meta-analysis.

Background: More sustained forms of atrial fibrillation (AF) are less amenable to treatment and associated with worse outcomes, but the incidence and predictors of AF progression are not well defined.

Objective: The purpose of this study was to perform a systematic review and meta-analysis assessing the incidence and predictors of AF progression.

Methods: PubMed, EMBASE, and the Cochrane Library were searched from inception to August 2017.
