Potential for leadless left bundle branch pacing for cardiac
resynchronization: a case report
Introduction: Left bundle branch pacing is a recently described form of
conduction system pacing which can correct left-bundle branch block and
deliver cardiac resynchronization therapy (CRT). The WiSE-CRT system
delivers leadless endocardial pacing and can improve symptoms and left
ventricular remodelling in CRT non-responders. Case Report: We describe
the case of a 57 year old male who underwent implantation of the
WiSE-CRT system after failed conventional CRT. Pacing the left bundle
during implant achieved superior electrical resynchronization and
equivalent hemodynamic response compared to pacing the lateral wall.
Conclusion: This case demonstrates the potential for leadless left
bundle branch pacing.
