Key result
Placement of a dual chamber implantable cardiac defibrillator and initiation of immunosuppressive therapy resulted in significant improvement of functional status in a patient with cardiac sarcoidosis.
Why the study?
Cardiac sarcoidosis predisposes patients to conduction abnormalities, ventricular arrhythmias, and sudden cardiac death, where early dual chamber ICD placement can prevent fatal complications.

This case highlights the importance of early ICD placement and immunosuppressive therapy in managing conduction abnormalities and preventing sudden cardiac death in patients with cardiac sarcoidosis.
May support immunosuppression in cardiac sarcoidosis conduction disease; hypothesis-generating and requires prospective confirmation before practice change.
Cardiac sarcoidosis is a rare complication of pulmonary sarcoidosis, causing granulomatous inflammation of the myocardium, ultimately resulting in infiltrative cardiomyopathy. Through fibrotic inflammation, cardiac sarcoidosis predisposes patients to multiple complications, such as conduction abnormalities, ventricular arrhythmias, heart failure, and sudden cardiac death. Due to the adverse prognosis of conduction abnormalities in these patients, dual chamber implantable cardiac defibrillator (ICD) therapy is beneficial in reducing mortality and morbidity. Early ICD placement can prevent further immune-driven fibrotic conduction complications. Here we present a case of a 50-year-old female who underwent ICD placement due to conduction abnormalities secondary to cardiac sarcoidosis.

Sunner et al. (2023) conducted a case report in Cardiac sarcoidosis (n=1). Implantable cardiac defibrillator (ICD) placement and immunosuppression was evaluated on Functional status improvement. Placement of a dual chamber implantable cardiac defibrillator and initiation of immunosuppressive therapy resulted in significant improvement of functional status in a patient with cardiac sarcoidosis.
