Left bundle branch area pacing in a young athlete with progressive cardiac conduction (Lev-Lenegre) disease

Abstract

We present the case of a professional soccer player affected by right bundle branch block and symptomatic 2:1 atrio-ventricular block during effort, due to progressive cardiac conduction disease (Lev-Lenegre disease), who received successful left bundle branch area pacing after a failed attempt at His bundle pacing. The electrocardiographic outcome of paced QRS was consistent with a rapid electrical activation of the left ventricle through the Purkinje system. The pursue of physiological pacing was preferred over conventional, given the young age of our patient and the expectedly high burden of stimulation, to reduce the long-term risk of pacing-induced cardiomyopathy.
