Magnetic Resonance Imaging in the Assessment of the Risk of Sudden Death in Cardiac Sarcoidosis: What Is Extensive or Significant Late Gadolinium Enhancement?

Background: Cardiac sarcoidosis involves a significant but difficult-to-define risk of sudden cardiac death (SCD). Current guidelines recommend consideration of an implantable cardioverter defibrillator for patients with extensive or significant myocardial late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging. However, extensive/significant LGE is not defined.

Economic burden of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) in Finland.

Objectives: Given that pulmonary arterial hypertension (PAH) and chronic thromboembolic hypertension (CTEPH) are rare yet severe subtypes of pulmonary hypertension significantly impacting patients' lives, this study analyzed the total societal costs of these conditions in Finland.

Methods: PAH (n = 247) and CTEPH (n = 177) patients diagnosed between 2008 and 2019 were analyzed for primary and specialty outpatient visits, emergency visits, hospitalizations, home and institutional care, sick leaves, disability pensions, and drug costs for 5 years before and after diagnosis.

Results: In PAH and CTEPH, annual specialty care number of outpatient visits increased from 3.

30-Year Trends in the Incidence, Characteristics, and Outcome of Cardiac Sarcoidosis in a Nationwide Cohort.

Background: Cardiac sarcoidosis (CS) is a rare but potentially fatal inflammatory cardiomyopathy.

Objectives: The authors studied temporal changes in the incidence, characteristics, and outcome of CS.

Methods: A retrospective analysis was made of a 30-year nationwide cohort of CS.

Incidence of Sudden Cardiac Death and Life-Threatening Arrhythmias in Clinically Manifest Cardiac Sarcoidosis With and Without Current Indications for an Implantable Cardioverter Defibrillator.

Background: Cardiac sarcoidosis (CS) predisposes to sudden cardiac death (SCD). Guidelines for implantable cardioverter defibrillators (ICDs) in CS have been issued by the Heart Rhythm Society in 2014 and the American College of Cardiology/American Heart Association/Heart Rhythm Society consortium in 2017. How well they discriminate high from low risk remains unknown.

Manifestations and Outcome of Cardiac Sarcoidosis and Idiopathic Giant Cell Myocarditis by 25-Year Nationwide Cohorts.

Background Cardiac sarcoidosis (CS) and giant cell myocarditis (GCM) share many histopathologic and clinical features. Whether they are parts of a one-disease continuum has been discussed. Methods and Results We compared medical record data of 351 CS and 28 GCM cases diagnosed in Finland since the late 1980s and followed until February 2018 for a composite end point of cardiac death, aborted sudden death, and heart transplantation.

Sudden death in cardiac sarcoidosis: an analysis of nationwide clinical and cause-of-death registries.

Aims: The present study was done to assess the role of sudden cardiac death (SCD) among the presenting manifestations of and fatalities from cardiac sarcoidosis (CS).

Methods And Results: We analysed altogether 351 cases of CS presenting from year 1998 through 2015 in Finland. There were 262 patients with a clinical diagnosis and treatment of CS, 27 patients with an initial lifetime diagnosis of giant cell myocarditis that was later converted to CS, and 62 cases detected at autopsy and identified by screening >820 000 death certificates from the national cause-of-death registry.

Outcome of Cardiac Sarcoidosis Presenting With High-Grade Atrioventricular Block.

Background: Symptomatic high-grade atrioventricular block (AVB) is the most common and often the only presenting manifestation (lone AVB) of cardiac sarcoidosis. Implantation of an intracardiac cardioverter defibrillator instead of a pacemaker is recommended, but the true risk of fatal arrhythmia, one incident to lone AVB in particular, remains poorly known.

Methods: We used Myocardial Inflammatory Diseases in Finland Study Group Registry to analyze the presentations, left ventricular (LV) function, pacemaker therapy, and ventricular arrhythmias in cardiac sarcoidosis.

F-18-fluorodeoxyglucose positron emission tomography-guided sampling of mediastinal lymph nodes in the diagnosis of cardiac sarcoidosis.

Histologic proof of granulomatous inflammation is prerequisite for the diagnosis of cardiac sarcoidosis (CS). Because of the limited sensitivity of endomyocardial biopsy (EMB), confirmation of sarcoidosis often has to be acquired from extracardiac biopsies. We set out to review our experience of F-18-fluorodeoxyglucose positron emission tomography (F-18-FDG PET) in guiding extracardiac tissue biopsies in suspected CS.

Usefulness of Cardiac Troponins as Markers of Early Treatment Response in Cardiac Sarcoidosis.

Evaluation and treatment of cardiac sarcoidosis (CS) suffer from lack of sensitive and easily repeatable markers of disease activity. We studied measurements of high-sensitivity cardiac troponin T or troponin I (hs-cTnT/I) taken at presentation and during treatment in 62 patients with new-onset CS (48 women, mean age 49 years). Hs-cTnT was measured in 50 patients and was elevated (>13 ng/L) at presentation in 26 of them (52%).

Cardiac sarcoidosis: epidemiology, characteristics, and outcome over 25 years in a nationwide study.

Background: This study was designed to assess the epidemiology, characteristics, and outcome of cardiac sarcoidosis (CS) in Finland.

Methods And Results: We identified in retrospect all adult (>18 years of age) patients diagnosed with histologically confirmed CS in Finland between 1988 and 2012. A total of 110 patients (71 women) 51±9 years of age (mean±SD) were found and followed up for outcome events to the end of 2013.
