sarcoidosis cardiac manifestations

Cardiac sarcoidosis is an infiltrative cardiomyopathy that results from granulomatous inflammation of the myocardium and may present with high-grade conduction disease, ventricular arrhythmias, and right or left ventricular dysfunction. Over the past several decades, the prevalence of cardiac sarcoidosis has increased. Definitive histological confirmation is often not possible, so clinicians frequently face uncertainty about the accuracy of diagnosis. Hence, the likelihood of cardiac sarcoidosis should be thought of as a continuum (definite, highly probable, probable, possible, low probability, unlikely) rather than in a binary fashion...

Sarcoidosis is a multisystem inflammatory condition presenting with the formation of noncaseating granulomas. These granulomas can be found in nearly every organ of the body, but in 90% of cases the lungs are involved. Osseous manifestations are seen in only 3% to 13% of cases and are typically seen alongside the more common pulmonary manifestations. These lesions can be misdiagnosed as metastatic cancer so biopsy, along with clinical correlation and exclusion of other diseases, is necessary to make the diagnosis...

BACKGROUND: The 2014 HRS consensus statement defines histological (definite) and clinical (probable) diagnostic categories of cardiac sarcoidosis (CS), but few studies have compared their arrhythmic phenotypes and outcomes. OBJECTIVE: Evaluate the electrophysiologic/arrhythmic phenotype and outcomes of patients with definite and probable CS. METHODS: We analyzed the arrhythmic/electrophysiologic phenotype in a single-center North American cohort of 388 patients (median age 56 years, 39% female) diagnosed with definite (n=58) or probable (n=330) CS (2000-2022)...

Sarcoidosis is a multisystem disorder of unknown etiology. The leading hypothesis involves an antigen-triggered dysregulated T-cell-driven immunologic response leading to non-necrotic granulomas. In cardiac sarcoidosis (CS), the inflammatory response can lead to fibrosis, culminating in clinical manifestations such as atrioventricular block and ventricular arrhythmias. Cardiac manifestations frequently present as first and isolated signs or may appear in conjunction with extracardiac manifestations. The incidence of sudden cardiac death (SCD) is high...

BACKGROUND: Due to the heterogeneity of sarcoidosis, there is a need to define clinical phenotypes to allow for tailoring of clinical care and identification of more homogenous populations to facilitate research. METHODS: We utilized data from a prospectively collected registry of sarcoidosis patients seen at a single quaternary referral center between January 2019 and February 2021. We used multiple correspondence analysis (MCA) and k-means clustering to investigate if the clusters previously identified in the GenPhenReSa study were reproducible in a US population...

A 40-year-old man, newly diagnosed with cardiac sarcoidosis (CS) presented with symptomatic ventricular tachycardia three days after starting steroid-based immunosuppressive therapy (IT). There was no clear guideline indication for implantable cardioverter-defibrillator (ICD) before the initiation of IT. Shortly after ICD implantation and the initiation of anti-arrhythmic drugs, recurring ventricular arrhythmias required titration of the anti-arrhythmic drug therapy. One-year follow-up assessment showed no significant arrhythmias and complete PET scan FDG uptake suppression...

UNLABELLED: The patient was a 68-year-old woman who experienced loss of consciousness owing to a seizure while walking and bruised her face. Twelve‑lead electrocardiography displayed a complete atrioventricular block. Transthoracic echocardiography displayed hypokinesis from the middle to apex of the myocardium. Emergency coronary angiography displayed no clear stenosis of the coronary arteries, and left ventriculography displayed takotsubo-like abnormal left ventricular wall motion...

Sarcoidosis is a non-caseating granulomatous disorder affecting multiple organs. Although the lungs are the most common site of presentation, extra-pulmonary manifestations involving the skin and heart can occur. Sarcoidosis affecting skull bone is uncommon and involvement of skin, heart, and skull bone all together, without pulmonary manifestations, is extremely rare. We report a 63-year-old Caucasian woman with a past history of cutaneous sarcoidosis and granulomatous skull bone lesions who presented with recurrent syncope...

Cardiac sarcoidosis (CS), a rare complication of systemic sarcoidosis, can have subtle or no symptoms. It is characterized by granuloma formation in the myocardium, which can occur in isolation or alongside systemic sarcoidosis. Clinical manifestations include conduction system disorders (e.g., atrioventricular block and ventricular tachyarrhythmia), heart failure, and sudden cardiac death. Timely evaluation and screening for CS are crucial, especially in systemic sarcoidosis patients with limited symptoms...

Sarcoidosis and the overlap syndrome of autoimmune hepatitis and primary biliary cholangitis (PBC) share common clinical, biological, and histological features. The simultaneous occurrence of these diseases have been reported in few cases and suggests that a common pathway which may contribute to granuloma formation in both conditions. We report the cases of two female patients having an association of sarcoidosis and inflammatory liver diseases. The first case is of a 61-year-old woman had been monitored for an overlap syndrome of PBC and autoimmune hepatitis (AIH)...

Cardiac sarcoidosis (CS) is increasingly recognized in the context of with otherwise unexplained electrical or structural heart disease due to improved diagnostic tools and awareness. Therefore, clinicians require improved understanding of this rare but fatal disease to care for these patients. The cardinal features of CS, include arrhythmias, atrio-ventricular conduction delay and cardiomyopathy. In addition to treatments tailored to these cardiac manifestations, immunosuppression plays a key role in active CS management...

Cardiac sarcoidosis (CS) can mimic any cardiomyopathy due to its ability to manifest with a variety of clinical presentations. The exact prevalence of CS remains unknown but has been reported ranging from 2.3% to as high as 29.9% among patients presenting with new onset cardiomyopathy and/or atrioventricular block. Early and accurate diagnosis of CS is often challenging due to the nature of disease progression and lack of diagnostic reference standard. The current diagnostic criteria for CS are lacking in sensitivity and specificity...

Cardiac involvement is a major cause of morbidity and mortality in patients with sarcoidosis. It is important to distinguish between clinical manifest diseases from clinically silent diseases. Advanced cardiac imaging studies are crucial in the diagnostic pathway. In suspected isolated cardiac sarcoidosis, it's key to rule out alternative diagnoses. Therapeutic options can be divided into immunosuppressive agents, guideline-directed medical therapy, antiarrhythmic medications, device/ablation therapy, and heart transplantation...

Cardiac sarcoidosis usually occurs as a manifestation of systemic sarcoidosis, even though isolated cardiac involvement is not uncommon. The usefulness of 68Ga-DOTANOC PET/CT in the diagnosis of CS has been previously documented in the literature. We present a case of cardiac sarcoidosis, where 68Ga-DOTANOC PET/CT was used for monitoring response to therapy.

Sarcoidosis is a multisystem granulomatous inflammatory disease of unknown etiology that can involve any organ. Ongoing dyspnea and dry cough in a young to middle-aged adult should increase the suspicion for sarcoidosis. Symptoms can present at any age and affect any organ system; however, pulmonary sarcoidosis is the most common. Extrapulmonary manifestations often involve cardiac, neurologic, ocular, and cutaneous systems. Patients with sarcoidosis can exhibit constitutional symptoms such as fever, unintentional weight loss, and fatigue...

BACKGROUND AND OBJECTIVES: Sarcoidosis is a multisystem inflammatory granulomatous disease. Among systemic sarcoidosis manifestations, cardiac or nervous system involvement can result in significant morbidity and mortality. We describe the overlapping incidence of cardiac sarcoidosis (CS) within a neurosarcoidosis (NS) cohort and determine the frequency of other nonsarcoid cardiac diseases in these patients. METHODS: We performed a retrospective chart review of patients evaluated at the University of Utah from 2010 to 2022...

INTRODUCTION: Atrioventricular block may be idiopathic or a secondary manifestation of an underlying systemic disease. Cardiac sarcoidosis is a significant underlying cause of high-grade atrioventricular block, posing diagnostic challenges and significant clinical implications. This study aimed to assess the prevalence and clinical characteristics of cardiac sarcoidosis among younger patients presenting with unexplained high-grade atrioventricular block. METHODS: We evaluated patients aged between 18 and 65 years presenting with unexplained high-grade atrioventricular block, who were systematically referred for cardiac magnetic resonance imaging (CMRI) and/or positron emission tomography-computed tomography (PET-CT) prior to pacemaker implantation...

PURPOSE: To describe a case of a previously healthy middle-aged male with an atypical choroidal mass and fatigue. METHODS: Case report. RESULTS: A 56-year-old Caucasian male presented with decreased vision in the right eye (OD) and a choroidal amelanotic mass OD with subretinal fluid. He received bevacizumab (1.25 mg/0.05 mL) injections by multiple providers without improvement in vision and with tumor progression. Visual acuity was 20/400 OD and 20/25 left eye (OS)...

Sarcoidosis is a granulomatous inflammatory disease of uncertain cause. It occurs most commonly in young and middle-aged adults and less frequently in children; therefore, few data on pediatric sarcoidosis exist in the literature. The diagnosis and management of sarcoidosis remain challenging because of diverse and often nonspecific clinical and imaging findings. In addition, the clinical picture varies widely by age. Prepubertal and adolescent patients often present with adult-like pulmonary disease; however, early-onset sarcoidosis is typically characterized by the triad of arthritis, uveitis, and skin rash...

BACKGROUND: The prognosis and later fatal arrhythmia in cardiac sarcoidosis (CS) with relatively preserved cardiac function were unclear. OBJECTIVES: This study aimed to evaluate the prognosis and arrhythmic events in patients with CS and mildly impaired cardiac function. METHODS: Data were collected from a nationwide Japanese cohort survey conducted in 57 hospitals (n = 420); 322 patients with CS with left ventricular ejection fraction (LVEF) >35% were investigated...
