Abstract:
We report the echocardiographic features of the first case of left bundle branch area pacing (LBBAP) in a woman with concurrent lamin and SCN5A mutations presenting with familial heart block. Left ventricular ejection fraction, global longitudinal strain, myocardial work, and septal-to-posterior activation pattern were conserved at 3 months postimplantation with excellent pacing parameters, demonstrating feasibility and short-term preservation of left ventricular mechanics of LBBAP in this very rare disease.

The pacemaker cells are located in two primary nodes: the sinoatrial (SA) node and the atrioventricular (AV) node. The SA node pacemaker cells can autonomously depolarize, triggering an action potential that leads to the...
