Sudden failure of ventricular pacing and recovery in a patient with cardiac sarcoidosis
نویسندگان
چکیده
A 76-year-old woman with sarcoidosis who had an implantable pacemaker for complete atrioventricular block was admitted with syncope. Electrocardiogram revealed ventricular pacing failure, and a marked rise in the ventricular pacing threshold. 18F-Fluorodeoxyglucose positron emission tomography (FDG-PET) indicated increased uptake of FDG in the ventricular septum. Three days after steroid therapy, the ventricular pacing threshold reverted to normal, and FDG-PET showed decreased FDG uptake in the ventricular septum. In this case report, we demonstrate that a sudden deterioration in the ventricular pacing threshold due to worsening cardiac sarcoidosis can be reversed with early steroid therapy.

Cardiac sarcoidosis: a comprehensive review
Sarcoidosis is a multisystem granulomatous disease of unknown etiology characterized by noncaseating granulomas in involved organs. Organs involved with sarcoidosis include lymph nodes, skin, lung, central nervous system, and eye. Only 40-50% of patients with cardiac sarcoidosis diagnosed at autopsy have the diagnosis made during their lifetime. Cardiac sarcoidosis can manifest itself as comple...

Sarcoidosis: A Systemic Inflammatory Disease Sarcoidosis is a systemic inflammatory disease characterized by the deposition of noncaseating granulomas in multiple organs, including the lungs, skin, central nervous system, and heart. The diagnosis of cardiac sarcoidosis is important because it confers a poorer prognosis, with an increased risk of ventricular arrhythmias, heart failure, and sudde...

To cite: Andrié R, Gaertner FC, Skowasch D. Thorax 2017;72:286–287. Patients with sarcoidosis with cardiac manifestation have a worse prognosis due to sudden cardiac death. The most important predictor of survival appears to be left ventricular function. A 25-year-old female patient was transferred to our hospital. Initial echocardiography demonstrated a reduced ejection fraction (EF) of 30%. B...

Cardiac sarcoidosis is a major cause of death in patients with systemic sarcoidosis. Cardiac manifestations are seen in 2.3% of the patients. Atrioventricular (AV) block is one of the common manifestations of cardiac sarcoidosis. Other presentations of cardiac involvement include congestive heart failure, ventricular arrhythmias, and sudden cardiac death. The presence of AV block in young patie...
