Predictors of Adverse Outcomes in Patients With Arrhythmogenic Right Ventricular Cardiomyopathy: A Meta-Analysis of Observational Studies

In conclusion, multiple risk factors have been associated with arrhythmic events in AC patients. However, larger studies are needed to discriminate those patients who will benefit from implantable cardioverter defibrillators.

CONCLUSION: Cardiac iron overload is associated with QTc prolongation in adolescents. QTc interval of 449 ms could be considered as a cut-off point of cardiac iron overload. PMID: 32419419 [PubMed - in process]

AbstractThe extracellular volume fraction (ECV) by T1 mapping can quantify diffuse myocardial fibrosis, and useful as a non-invasive marker for risk stratification for patients with non-ischemic dilated cardiomyopathy (NIDCM). Prolonged QRS interval on electrocardiogram is related to worse clinical outcome for heart failure patients. The purpose of this study was to evaluate the prognostic value of the combination of ECV and QRS duration for NIDCM patients. A total of 60 NIDCM patients (mean age 61  ± 12 years, mean left ventricular ejection fraction 37 ± 10%, mean QRS duratio...

Transthyretin cardiac amyloidosis (ATTR-CA) is an increasingly recognized infiltrative cardiomyopathy in which conduction system disease is common. The aim of our study was to define the incidence and prevalence of high-grade atrioventricular (AV) block requiring pacemaker implantation in our quaternary referral center. This was a single-center retrospective cohort study of 369 consecutive patients with ATTR-CA who underwent 12-lead electrocardiogram (ECG) at the time of ATTR-CA diagnosis. During a mean follow-up of 28 months, serial ECGs and the electronic medical record were examined for the development of high-grade AV ...

Written by Pendell MeyersA man in his 50s with HTN, HLD, obesity, and restrictive lung disease presented with shortness of breath worsening over the past 3 days. He also had a cough and subjective fevers. He denied chest pain. His vitals were within normal limits.Here is his triage ECG (no baseline available):What do you think?Findings: - sinus rhythm at about 100 bpm - STE in I and aVL (meets STEMI criteria) - hint of STD in III and aVF - STD in V1 and V2 - hyperacute T-waves in I and aVL (with reciprocal negative hyperacute T in III)Interpretation:This is definitive evidence of acute transmural i...

Aims The diagnostic performance of the new Peguero–Lo Presti ECG criteria for left ventricular hypertrophy (LVH) has not been validated by cardiac magnetic resonance (CMR). The aim of this study was to evaluate and compare the diagnostic performance of Peguero–Lo Presti, Cornell and Sokolow--Lyon voltage criteria for LVH as defined by CMR in an all-comers European population. Methods A total of 240 consecutive patients referred for CMR who had a concomitant electrocardiogram for review were evaluated. LVH group patients were defined according to the reference values for sex and age of left ventricular mass...

AbstractMyocarditis most often affects otherwise healthy athletes and is one of the leading causes of sudden death in children and young adults. Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetically determined heart muscle disorder with increased risk for paroxysmal ventricular arrhythmias and sudden cardiac death. The clinical picture of myocarditis and ARVC may overlap during the early stages of cardiomyopathy, which may lead to misdiagnosis. In the literature, we found several cases that presented with episodes of myocarditis and ended up with a diagnosis of arrhythmogenic cardiomyopathy, mostly of the...

AbstractHypertrophic cardiomyopathy (HCM) is the most frequent cardiac disease with genetic substrate, affecting about 0.2 –0.5% of the population. While most of the patients with HCM have a relatively good prognosis, some are at increased risk of adverse events. Identifying such patients at risk is important for optimal treatment and follow-up. While clinical and electrocardiographic information plays an important ro le, echocardiography remains the cornerstone in assessing patients with HCM. In this review, we discuss the role of echocardiography in diagnosing HCM, the key features that differentiate HCM from other...
