Introduction: Sarcoidosis is described as a systemic condition characterized by non-caseating granulomas in multiple organs. In this report, we present an unusual manifestation of cardiac sarcoidosis and review management strategies. Case presentation: A 29-year-old African-American man presented with weight loss, fatigue, dyspnea, palpitations, night sweats, painless left eye redness and bilateral leg pain over the course of three months. His physical exam revealed left conjunctival congestion and bilateral crackles on auscultation...

Protein losing enteropathy (PLE) has been associated with more than 60 different conditions, including nearly all gastrointestinal diseases (Crohn's disease, celiac, Whipple's, intestinal infections, and so on) and a large number of non-gut conditions (cardiac and liver disease, lupus, sarcoidosis, and so on). This review presents the first attempt to quantitatively understand the magnitude of the PLE in relation to the associated pathology for three different disease categories: 1) increased lymphatic pressure (e...

A 66-year-old woman presented with frequent premature ventricular contractions (PVC) and akinesis of the basal septum on echocardiography. Coronary angiography was normal. Cardiac magnetic resonance showed mid-wall enhancement. Positron emission tomography showed a perfusion defect at the same location using 13N-ammonia, but increased 18-fluorodeoxyglucose uptake. These findings supported the diagnosis of cardiac sarcoidosis. High-dose steroids initially reduced frequency of PVCs but had to be withdrawn due to severe side effects...

BACKGROUND: Although rare, cardiac sarcoidosis (CS) is potentially fatal. Early diagnosis and intervention are essential, but histopathologic diagnosis is limited. We aimed to detect Propionibacterium acnes, a commonly implicated etiologic agent of sarcoidosis, in myocardial tissues obtained from CS patients. METHODS AND RESULTS: We examined formalin-fixed paraffin-embedded myocardial tissues obtained by surgery or autopsy and endomyocardial biopsy from patients with CS (n = 26; CS-group), myocarditis (n = 15; M-group), or other cardiomyopathies (n = 39; CM-group) using immunohistochemistry (IHC) with a P...

During the past years, endomyocardial biopsy (EMB) has gradually spread into clinical practice. However, the role of EMB in the diagnosis and treatment of cardiovascular diseases remains a controversial issue, especially in the setting of unexplained ventricular arrhythmias. Areas covered: This review describes the methodology of EMB guided by combined use of three-dimensional electroanatomical mapping systems and intracardiac echo and summarizes the classical, fluoroscopy-guided EMB technique. Finally, the personal experience acquired with the 'electrophysiologist-made' integration methodology has been reported...

OBJECTIVE: Cardiac involvement in sarcoidosis can present in various ways, with atrioventricular (AV) block and ventricular arrhythmias being the most common signs. Because of initial non-specific findings, diagnosis can be a challenge. Very few data can support treatment decisions as cardiac manifestations of this systemic disorder are rare. METHODS AND RESULTS: We reviewed current guidelines, cohort studies, and expert opinions concerning diagnosis and treatment of cardiac sarcoidosis...

Sarcoidosis is a systemic granulomatous disease of unknown aetiology, which is characterized by bilateral hilar lymphadenopathy and pulmonary disease. Clinically detected cardiac involvement occurs in 5% of sarcoid patients, although cardiac manifestations are discovered in 25% of the cases at autopsy. Sarcoid heart disease frequently causes atrioventricular block. The authors present the case of a 44-year-old man with bradycardia. On admission, second degree Mobitz II, then third degree atrioventricular block was diagnosed...

REVIEW
Matthew M Zipse, Wendy S Tzou
Sudden cardiac death (SCD) risk assessment among patients with nonischemic cardiomyopathy (NICM) has been has been less straightforward than for patients with ischemic cardiomyopathy. The common surrogate that has been associated with highest SCD risk for all cardiomyopathies, and which has been universally used to guide implantation of primary-prevention implantable cardioverter-defibrillators (ICDs), is left ventricular ejection fraction (LVEF) ≤35%. However, this practice has been called into question, especially in light of recent trials suggesting that ICD treatment may not be of additional survival benefit among those with NICM treated with optimal medical therapy...

A 67-year-old man with coronary artery disease (CAD) and left anterior descending artery (LAD) stent presented with symptomatic monomorphic ventricular tachycardia (VT) at a rate of 190 bpm requiring cardioversion. ECG showed left bundle branch block pattern and inferior axis, suggestive of a right ventricular outflow tract (RVOT) focus rather than left ventricular scar due to LAD territory myocardial infarction (MI). Echocardiography showed normal wall motion. Angiography revealed a patent mid-LAD stent. Cardiac MRI with delayed postcontrast sequence revealed several regions of hyperenhancement abnormality within the basal portion of the interventricular septum...

PURPOSE OF REVIEW: To address the current recommendations for screening, diagnosis, and treatment of cardiac sarcoidosis and the difficulties to put these recommendations into clinical practice. RECENT FINDINGS: The incidence of cardiac sarcoidosis appears to be higher than earlier reported, probably because of improved imaging techniques. Late gadolinium enhancement with cardiac MRI (LGE-CMR) and fluorodeoxyglucose positron emission tomography obtained a central role in the diagnostic algorithm and monitoring of disease activity...

Sarcoidosis is a granulomatous lung disorder of unknown cause. The majority of individuals with sarcoidosis spontaneously achieve full remission (uncomplicated sarcoidosis), however, ~20% of sarcoidosis-affected individuals experience progressive lung disease or cardiac and nervous system involvement (complicated sarcoidosis). We investigated peripheral blood mononuclear cell (PBMC) microRNA and protein-coding gene expression data from healthy controls and patients with uncomplicated or complicated sarcoidosis...

BACKGROUND: Cardiac sarcoidosis (CS) is an uncommon and under-recognized disease which most frequently presents with atrioventricular (AV) block and may also present with ventricular arrhythmias and left ventricular (LV) systolic dysfunction. Because of its protean clinical manifestations, confirming a diagnosis of CS is often challenging. METHODS: We report two cases where patients presented with atrioventricular (AV) block without evidence of underlying myocardial disease, underwent chronic dual-chamber pacing, and presented several years later with severe LV systolic dysfunction...

Recently reported in Europe and United States, disseminated Mycobacterium chimaera infection is a novel clinical entity linked to point contamination of Stockert 3T heater-cooler units used for cardiopulmonary bypass. We present here the first two cases in Canada. Both patients presented with nonspecific extracardiac symptoms 1 year after undergoing minimally invasive mitral surgical repair. Before the right diagnosis was established, the patients were initially treated with prednisone for suspected sarcoidosis...

OBJECTIVES: The purpose of this study was to explore the diagnostic usefulness of hybrid cardiac magnetic resonance (CMR) and positron emission tomography (PET) using 18F-fluorodeoxyglucose (FDG) for active cardiac sarcoidosis. BACKGROUND: Active cardiac sarcoidosis (aCS) is underdiagnosed and has a high mortality. METHODS: Patients with clinical suspicion of aCS underwent hybrid CMR/PET with late gadolinium enhancement (LGE) and FDG to assess the pattern of injury and disease activity, respectively...

Majority of ventricular tachycardias (VTs) are caused by scar-related macroreentry in patients with cardiac sarcoidosis. These VTs usually exhibit the reentry circuit on electroanatomic maps. We here describe a rare case of VT that exhibits a focal activation pattern on the electroanatomic map despite reentrant VT.
