Key result
Direct left bundle branch permanent pacing was successfully used for cardiac resynchronization therapy in a patient with a relative contraindication to conventional CRT.
Why the study?
Because the coronary sinus is targeted by an increasing number of percutaneous procedures, conventional CRT may not be feasible or preferable, requiring alternative approaches.
Case Report (n=1)
Left bundle branch pacing (LBBP) may represent a viable alternative for cardiac resynchronization therapy when the coronary sinus is not suitable for conventional left ventricular lead implantation.
LBBP may offer CRT alternative when coronary sinus inaccessible; hypothesis-generating, needs prospective validation.
Background: Coronary sinus is the target of an increasing number of percutaneous interventional procedures. Thus, in some patients, conventional cardiac resynchronization therapy (CRT) may not be feasible or preferable, and 'alternative' CRT approaches should be applied. Case summary: We present the case of a successful CRT via direct left bundle branch permanent pacing (LBBP) in a patient with relative contraindication to conventional CRT because of previous percutaneous indirect mitral annuloplasty. Discussion: LBBP is emerging as a promising technique for physiological cardiac pacing and CRT. It may represent the technique of choice when coronary sinus is not viable for the implant of a conventional left ventricular catheter.

Dell’Era et al. (2022) conducted a case report in Indication for cardiac resynchronization therapy with relative contraindication to conventional CRT (n=1). Direct left bundle branch permanent pacing (LBBP) was evaluated on Successful cardiac resynchronization therapy. Direct left bundle branch permanent pacing was successfully used for cardiac resynchronization therapy in a patient with a relative contraindication to conventional CRT.
