Left bundle branch area pacing in patients with transthyretin cardiac amyloidosis: a case series.

Background: Transthyretin cardiac amyloidosis is associated with various arrhythmias, including atrioventricular block. Despite this correlation, established treatments for transthyretin cardiac amyloidosis-associated arrhythmias are lacking. Left bundle branch area pacing is a promising physiological pacing technique.
