Cardiac sarcoidosis: Case presentation and Review of the literature

Isolated Cardiac Sarcoidosis Presenting as Torsades de Pointes in a Patient With Non-ischemic Cardiomyopathy: A Case Report

Sarcoidosis is an immune-mediated, inflammatory, non-caseating-granulomatous disease that can virtually infiltrate any organ. Cardiac sarcoidosis is a leading cause of death in patients with sarcoidosis. Its clinical presentation is highly heterogenous and unpredictable, ranging from asymptomatic to life-threatening conduction disturbances, such as ventricular arrhythmias, and heart failure. Herein, we report a case of isolated cardiac sarcoidosis presenting as sinus bradycardia with first-degree atrioventricular block and an episode of non-sustained polymorphic ventricular tachycardia in a 42-year-old male with non-ischemic cardiomyopathy. He was diagnosed by cardiac magnetic resonance imaging and positron emission tomography with fluorodeoxyglucose and treated with oral prednisone.

Cardiac Sarcoidosis-Induced Heart Failure

Sarcoidosis is a common disease with the incidence of cardiac involvement varying. Cardiac sarcoidosis should be kept on the differential when young patients present with acute heart failure, conduction abnormalities or new arrhythmia. Cardiac involvement in sarcoidosis must be diagnosed early and treated aggressively. Here we present a patient who presented with shortness of breath and was found to have significant heart failure with reduced ejection fraction caused by sarcoidosis with cardiac involvement. She was treated with optimization of medical therapy for heart failure and eventually required implantable cardioverter defibrillator (ICD) placement.
