AI Article Synopsis

  • Arrhythmogenic cardiomyopathy (ACM) is a serious heart condition that can lead to sudden death and is influenced by various biological pathways, particularly the Wnt signaling pathway.
  • GSK3β is a key enzyme in this pathway, and research indicates that blocking it could potentially protect against or reverse the harmful symptoms of ACM in experimental settings.
  • The upcoming phase 2 TaRGET clinical trial will assess the effectiveness of GSK3β inhibition in ACM patients, while weighing its possible risks, such as arrhythmias and cancer.

Article Abstract

Arrhythmogenic cardiomyopathy is a primary myocardial disease and a major cause of sudden death in all populations of the world. Canonical Wnt signalling is a critical pathway controlling numerous processes including cellular differentiation, hypertrophy and development. GSK3β is a ubiquitous serine/threonine kinase, which acts downstream of Wnt to promote protein ubiquitination and proteasomal degradation. Several studies now suggest that inhibiting GSK3β can prevent and reverse key pathognomonic features of ACM in a range of experimental models. However, varying concerns are reported throughout the literature including the risk of paradoxical arrhythmias, cancer and off-target effects in upstream or downstream pathways. CLINICAL RELEVANCE: In light of the start of the phase 2 TaRGET clinical trial, designed to evaluate the potential therapeutic efficacy of GSK3β inhibition in patients with arrhythmogenic cardiomyopathy, this report aims to review the advantages and disadvantages of this strategy.

Naxos disease is a rare autosomal recessive condition combining arrhythmogenic right ventricular cardiomyopathy, woolly hair, and palmoplantar keratoderma. The first identified causative variant was in the gene encoding the desmosomal protein plakoglobin. Naxos disease exhibits fibro-fatty myocardial replacement with immunohistological abnormalities in cardiac protein and signaling pathways, highlighting the role of inflammation and potential anti-inflammatory treatments.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heritable myocardial condition that mostly affects the right ventricle (RV). Atrial involvement is poorly understood and the evidence for atrial involvement remains limited. In this case report, we describe an 18-year-old woman who had ARVC with the atrial tachyarrhythmia and initially presented with palpitations.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is typically diagnosed following an arrhythmic event or during screening after a family member experiences sudden cardiac death. Implantation of a defibrillator (ICD) improves survival but can be associated with morbidity and risks, an important consideration within a shared decision-making context. This study examined patient decisional needs and preferences surrounding ARVC screening and prophylactic ICD implantation.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is the classic phenotype of arrhythmogenic cardiomyopathy. ARVC in twins have been reported rarely. Herein, we report an unusual case of young monozygotic twins with early disease onset presenting different course of disease progression and clinical manifestations.

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is a right ventricular disease caused by desmosomal gene mutations leading to fibro-fatty replacement of the myocardium causing ventricular arrhythmias such as ventricular tachycardia (VT). A 59-year-old female presented with new onset VT manifesting as shortness of breath and chest discomfort. Diagnostic workup revealed right ventricular dilation/dysfunction on echocardiogram, VT with left bundle branch block (LBBB) and diffuse T wave inversions (TWIs) on EKG.
