Key result
Permanent pacing in cardiac sarcoidosis is linked to a high incidence of PICM.
Why the study?
Patients with cardiac sarcoidosis commonly present with advanced conduction system disease, but there are no recommendations on when to implant CRT.
The text highlights a gap in current guidelines regarding when to implant cardiac resynchronization therapy in patients with cardiac sarcoidosis who require pacing.
Answers are grounded in this paper and cite their sources.
May warrant closer monitoring or alternative strategies in cardiac sarcoidosis; hypothesis-generating and requires prospective validation.
Sarcoidosis is a multisystem, inflammatory granulomatous disease of unknown etiology. Patients with clinically manifest cardiac sarcoidosis (CS) commonly present with advanced conduction system disease. Current guidelines advise permanent pacing for these patients, and it is further recommended that they receive implantable cardioverter defibrillators (ICDs) because of the risk of sudden cardiac death.(1) However, there are no recommendations on when to implant cardiac resynchronization therapy (CRT).

Nelson et al. (2026) studied Cardiac sarcoidosis. Permanent pacing was evaluated. Permanent pacing in patients with cardiac sarcoidosis is associated with a high incidence of pacing-induced cardiomyopathy.
