The Spectrum of Cardiac Involvement in Erdheim-Chester Disease is Broader than Previously Thought

EP News: Case Reports

Sarcoidosis is a granulomatous disease that can present broadly from multisystem disease to very focal manifestations, including as ventricular tachycardia (VT) in the setting of cardiac involvement. With improved awareness of the intersection of inflammatory triggers and substrate in patients who present with VT, the spectrum of cardiac involvement in sarcoidosis has been expanded. Ando et al (https://doi.org/10.1016/j.hrcr.2021.08.014) shared a case of a 50-year-old man presented with frequent premature ventricular complexes (PVCs) (right bundle branch block morphology and an rS pattern in the inferior leads and lead V6, suggestive of a posteromedial papillary muscle origin) on routine clinical examination.

Getting to the heart of the matter: diagnostic tools and therapeutic approach to cardiac involvement in Behçet syndrome A Tunisian case series.

The aim was to investigate the frequency and spectrum of cardiac involvement (CI) in patients with Behçet syndrome (BS) in the Tunisian context, and to assess the clinical and imaging features, treatment, and outcomes. We retrospectively retrieved the medical records of patients with CI among 220 BS patients admitted to the hospital internal medicine department between February 2006 and April 2019, who fulfilled the International Study Group diagnostic criteria for BS. Ten patients (8 men, 2 women) were eligible for the study. Mean age was 37.3 years. Three patients had 2 isolated episodes of cardiac BS. The different types of CI were coronary artery disease (5/10), intracardiac thrombus (4/10), pericarditis (1/10), myocarditis (1/10), and myocardial fibrosis (1/10). Five patients had associated vascular involvement (50%). Medical treatment was based on corticosteroids and colchicine in all patients (100%), anticoagulants in 8 (80%), and cyclophosphamide followed by azathioprine in 9 (90%). The clinical course was favorable in 9 patients; 1 patient died. CI remains an important feature of BS because of its association with increased risk of mortality and morbidity. Therefore, early screening and detection with imaging methods are paramount. Also, better cooperation between rheumatologists and cardiologists could improve outcomes.

Spectrum of cardiac involvement in patients with dengue fever

BackgroundDengue fever (DF) is an infectious disease of viral origin common in the tropics. Studies on a large number of patients with dengue infection to assess associated cardiac involvement are rare. MethodsWe analyzed the incidence and spectrum of cardiac abnormalities in 320 patients with dengue fever admitted to our hospital located in an endemic area for dengue infection. All patients were evaluated following the WHO guidelines. Those confirmed to have dengue infection by serology had detailed clinical evaluation, 12‑lead electrocardiography (ECG), assay for cardiac markers (troponin T, CK-MB, NT Pro BNP) and 2-D echocardiography. ResultsAmong the 320 patients selected for the study 112 (35%) had changes of cardiac involvement as detected by investigations. Changes in ECG were seen in all of them. Sinus bradycardia in spite of fever was the most common abnormality (n = 63;19.7%). Forty-two (13.1%) patients had left ventricular ejection fraction less than 40%. Forty-eight patients (15%) had increased serum levels of troponin-T. Serum levels of CK-MB were elevated in 34 (10.6%) and serum levels of NT-pro BNP was increased in 19 (5.9%). Fourteen patients died and all of them had abnormalities in electrocardiogram, echocardiogram and serum markers. ConclusionOur study reveals that cardiac involvement in patients with dengue infection is not uncommon. We found that ECHO or ECG abnormalities or elevated serum levels of markers of cardiac injury are predictors of risk for adverse outcome. Absence of these abnormalities has a 100% negative predictive value.

MEFV gene mutations and cardiac phenotype in children with familial Mediterranean fever: a cohort study

BackgroundFamilial Mediterranean fever (FMF) is the most common autoinflammatory disorder in the world. It is characterized by recurrent febrile inflammatory attacks of serosal and synovial membranes. MEFV gene mutations are responsible for the disease and its protein product, pyrin or marenostrin, plays an essential role in the regulation of the inflammatory reactions. Although the disease may carry a potential for cardiovascular disorders because of sustained inflammation during its course, the spectrum of cardiac involvement in children with FMF has not been well studied. We aimed at defining the frequency and spectrum of cardiac affection in children with FMF. The correlation between these affections and MEFV gene mutations was searched for to establish the relationship between cardiac phenotype and the patient's genotype in FMF.MethodsThe present work is a cohort study including 55 patients with the clinical diagnosis of FMF based on the Tel-Hashomere criteria, confirmed by genetic analysis showing homozygous or compound heterozygous mutation of MEFV genes. Fifty age- and sex-matched normal children were included as controls. The entire study group underwent detailed cardiac examination, 12-lead ECG and echocardiography. All data was statistically analysed using SPSS version-15.ResultsPatients had an average age of 8.5+/−4.2 years; with an average disease duration of 2.1+/−2.2 years; 28 were males. All controls showed no MEVF gene mutations. The most frequent gene mutation of the studied cases was E148Q mutation seen in 34% of cases and the most frequent compound mutation was E148Q/V726A seen in 16.6% of cases. Echocardiographic examination revealed pericardial effusion in nine patients. Twelve had aortic regurgitation; nine had mitral regurgitation and six had pulmonary regurgitation. The most common mutation associated with pericardial effusion was E148Q/V726A in 5/9 of cases. Valvular involvement were significantly more common in FMF patients with gene mutations. Also cardiac involvement was more common in patients with positive consanguinity. However, these cardiac manifestations showed no correlation to age, family history of FMF, or response to therapy or laboratory data.ConclusionsIn our cohort of children with FMF, cardiac involvement appears to be common. Pericardial effusions are significantly related to presence of mutation types E48Q, P 369S, V726A. These associations may warrant genetic screening of children with FMF to detect cardiac risk.

Spectrum of Cardiac Involvement in Neonatal Lupus

'Neonatal' lupus erythematosus (NLE) describes a clinical spectrum of cardiac and non-cardiac abnormalities observed in neonates and foetuses whose mothers have the auto-antibodies anti-SSA/Ro (anti-Ro) and anti-SSB/La (anti-La). Of the cardiac abnormalities, congenital AVB is the most common cardiovascular abnormality found in affected foetuses and infants. Many other cardiovascular manifestations of NLE have been more recently recognized including atrial and ventricular arrhythmias and other conduction abnormalities, myocarditis, cardiomyopathy often with endocardiofibroelastosis and structural heart disease, particularly valvar lesions. In this report, the spectrum of cardiovascular manifestations observed in foetuses and infants with NLE are reviewed and the pathogenesis, diagnosis and clinical outcomes are briefly discussed.

Spectrum of cardiac involvement in Friedreich's ataxia: Clinical, electrocardiographic and echocardiographic observations

Combined 2-dimensional and M-mode echocardiography was used to assess the cardiac status of 22 patients with Friedreich's ataxia, and the findings were correlated with the clinical and electrocardiographic (ECG) data. Mean age at onset of Friedreich's ataxia was 8 years (range 3 to 18); mean age at echocardiography was 18 years (range 8 to 39). Echocardiographic findings were abnormal in 19 patients (86%). The 3 patients with normal echocardiographic findings did not have cardiac symptoms, but 1 had ECG repolarization abnormalities. Concentric left ventricular (LV) thickening, the most common echocardiographic finding, was found in 15 patients (68%) and in all 15 the papillary muscles were thickened. These 15 patients had ECG repolarization abnormalities and 5 had left-axis deviation; however, only 3 satisfied ECG criteria for LV or right ventricular hypertrophy. Two of the 15 patients (9%) had symptoms of heart failure. Two patients had asymmetric septal thickening without clinical evidence of LV outflow tract obstruction; neither had cardiac symptoms, but both had ECG repolarization abnormalities. Two patients showed a dilated cardiomyopathy pattern; both had heart failure and atrial flutter. One of these patients died, and necropsy revealed 4-chamber cardiac dilatation, biventricular hypertrophy and histologic findings of diffuse interstitial fibrosis, myocellular hypertrophy and necrosis. This study revealed a wide spectrum of cardiac abnormalities in patients with Friedreich's ataxia.
