Aims: Cardiac sarcoidosis (CS) is associated with a poor prognosis. Important features of CS include heart failure, conduction abnormalities, and ventricular arrhythmias. Ventricular tachycardia (VT) is often refractory to antiarrhythmic drugs (AAD) and immunosuppression. Catheter ablation has emerged as a treatment option for recurrent VT. However, data on the efficacy and outcomes of VT ablation in this context are sparse. Methods and results: A systematic search was performed on PubMed, EMBASE, and Cochrane database (from inception to September 2016) with included studies providing a minimum of information on CS patients undergoing VT ablation: age, gender, VT cycle length, CS diagnosis criteria, and baseline medications...

BACKGROUND: Little is known about the suitability of implantable cardioverter defibrillator (ICD) implantation in patients with cardiac sarcoidosis (CS). We evaluated the efficacy of ICD implantation in patients with CS, including suspected CS, compared with those with idiopathic dilated cardiomyopathy (DCM). METHODS: A total of 102 consecutive patients with definite CS, suspected CS, or DCM who underwent ICD implantation were enrolled. The endpoint was the first documentation of appropriate ICD therapy for ventricular tachyarrhythmias...

INTRODUCTION: Treating ventricular tachycardia (VT) in patients with cardiac sarcoidosis (CS) is challenging as patients present in different phase of the disease (inflammatory, scar or sometimes both). A customized approach to treatment is required for better outcomes. We describe our experience in the management of VT in CS based on the phase of the disease. METHODS AND RESULTS: Patients were considered to have myocardial inflammation if there was an increased myocardial (18) Fluoro Deoxy Glucose (FDG) uptake in PET-CT scan of the chest (n=14)...

CASE: A 50 year old African-American woman with diabetes, hypertension, and hyperlipidemia presented with progressively worsening retro-sternal chest pain, exacerbated by activity and relieved by rest. She also endorsed a thirty-pound unintentional weight loss, and dysphagia. She was dysarthric with left-sided Bell's Palsy and a palpable left axillary lymph node. She had been evaluated at several hospitals in the previous months for similar typical chest pain. Her troponin values were normal, and an EKG showed T-wave inversions in leads I and aVL...

The National Institute of Health defined cardiomyopathy as diseases of the heart muscle. These myocardial diseases have different etiology, structure and treatment. This review highlights the key imaging features of different myocardial diseases. It provides information on myocardial structure/orientation, perfusion, function and viability in diseases related to cardiomyopathy. The standard cardiac magnetic resonance imaging (MRI) sequences can reveal insight on left ventricular (LV) mass, volumes and regional contractile function in all types of cardiomyopathy diseases...

REVIEW

PURPOSE OF REVIEW: Inflammation is a key player in a wide range of cardiovascular and myocardial diseases. Given the numerous implications of inflammatory processes in disease initiation and progression, functional imaging modalities including positron emission tomography (PET) represent valuable diagnostic, prognostic, and monitoring tools in patient management. Since increased glucose metabolism is a hallmark of inflammation, PET using the radiolabeled glucose analog [(18)F]-2-deoxy-2-fluoro-d-glucose (FDG) is the mainstay diagnostic test for nuclear imaging of (cardiac) inflammation...

In independent studies, abnormal global longitudinal strain (GLS) and myocardial inflammation or scar detected by 18F-fludeoxyglucose positron emission tomography (FDG-PET) are associated with poor prognosis among patients with high likelihood for cardiac sarcoidosis. However, commonly used imaging modalities have not been evaluated in the same population. Our goals were to examine the relation between GLS and FDG-PET, and to evaluate the incremental prognostic value of these imaging techniques for predicting major adverse cardiac events (MACE) in patients suspected to have cardiac sarcoidosis...

Aims: Sarcoidosis with cardiac involvement is a rare pathological condition, and therefore cardiac resynchronization therapy (CRT) for patients with cardiac sarcoidosis is even further rare. We aimed to clarify the clinical features of patients with cardiac sarcoidosis who received CRT. Methods and results: We retrospectively reviewed the clinical data on CRT at three cardiovascular centres to detect cardiac sarcoidosis patients. We identified 18 (8.9%) patients with cardiac sarcoidosis who met the inclusion criteria out of 202 with systolic heart failure who received CRT based on the guidelines...

OBJECTIVES: The goal of this study was to assess the independent and collective diagnostic value of various modalities in cardiac sarcoidosis, delineate the role of cardiac magnetic resonance (CMR), and identify patients at risk. BACKGROUND: Cardiac sarcoidosis is associated with increased morbidity and mortality. CMR is a key modality in the evaluation of patients with cardiac symptoms, but the complementary role of CMR to conventional tests for the diagnosis of cardiac sarcoidosis is not fully defined...

OBJECTIVE: Small fiber neuropathy commonly affects patients with sarcoidosis and is often refractory to standard immunosuppressive therapies used for systemic disease. The clinical features of sarcoidosis-associated small fiber neuropathy (SSFN) and its response to medical therapy have not been described in a large population. METHODS: We performed a retrospective review of patients with SSFN seen at the Cleveland Clinic over a 4-year period. RESULTS: SSFN was identified in 143 individuals although other causes of neuropathy were found in 28 cases...

BACKGROUND: Prior studies have shown that late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) and fluorodeoxyglucose (FDG) positron emission tomography (PET) confer incremental risk assessment in patients with cardiac sarcoidosis (CS). However, the incremental prognostic value of the combined use of LGE and FDG compared to either test alone has not been investigated, and this is the aim of the present study. METHODS: Retrospective observational study of 56 symptomatic patients with high clinical suspicion for CS who underwent LGE-CMR and FDG-PET and were followed for the occurrence of death and/or malignant ventricular arrhythmias (VA)...

Sarcoidosis is a granulomatous disease of unknown etiology affecting any organ, microscopically characterized by noncaseating granulomata. Cardiac involvement in sarcoidosis has been reported. It might be symptomatic or not and even revealed by sudden death. Heart conduction system is rarely investigated at autopsy, even in cases of sudden cardiac death. We present a case of a 32-year-old woman who died suddenly. The examination of the heart conduction system revealed a cardiac sarcoidosis that could explain the sudden death...

Uptake of the radiopharmaceutical F-FDG visualized by PET imaging can reflect abnormal myocardial inflammation. When utilized in conjunction with other imaging modalities, such as echocardiography, PET F-FDG imaging can help distinguish between active cardiac sarcoidosis and other etiologies of nonischemic cardiomyopathy. We present a case of a 46-year-old man with nonischemic cardiomyopathy and ventricular tachycardia who underwent an echocardiogram suggestive of cardiac Chagas disease. A subsequent F-FDG PET demonstrated abnormal hypermetabolism...

Recent studies have reported the usefulness of (18)F-fluoro-2-deoxyglucose positron emission tomography (FDG-PET) in aiding with the diagnosis and management of patients with cardiac sarcoidosis (CS). However, the image interpretation of FDG-PET for CS is sometimes challenging. We sought to investigate the inter- and intra-observer agreement and explore factors which lead to important discrepancies between readers. METHODS: We studied consecutive patients with no significant coronary artery disease who were referred for assessment of CS...
