A 47-year-old woman diagnosed with arrhythmogenic right ventricular cardiomyopathy, was studied at our institution with palpitations, progressive dyspnoea and cyanosis over a 3-year period. Her haemoglobin saturation was 76.1%. The transthoracic echocardiogram showed that both right atrium and ventricle were dilated, with diffuse akinetic and hypokinetic areas. Radionuclide scintigraphy, angiography and magnetic resonance imaging showed dilated and severe dysfunction of the right ventricle, with depressed ejection fraction (0.16), and bulging at the level of the right ventricular anterior wall areas. Doppler examination revealed a right-to-left interatrial shunt through a patent foramen ovale. Contrast transoesophageal echocardiography confirmed the right-to-left shunting. Considering the clinical symptoms were severe and refractory to medical treatment, she was referred for cardiac transplantation. Unfortunately the patient died suddenly a few weeks later.

Identification of Biomarkers of Arrhythmogenic Cardiomyopathy (ACM) by Plasma Proteomics.

Service de Cardiologie Pédiatrique, Hôpital la Rabta Tunis, Tunis 1007, Tunisia.
The pathophysiology of arrhythmogenic cardiomyopathy (ACM), previously known as arrhythmogenic right ventricular cardiomyopathy (ARVC), and its specific biological features remain poorly understood. High-throughput plasma proteomic profiling, a powerful tool for gaining insights into disease pathophysiology at the systems biology level, has not been used to study ACM. This study aimed at characterizing plasmatic protein changes in patients with ACM, which were compared with those of healthy controls, and at exploring the potential role of the identified proteins as biomarkers for diagnosis and monitoring.

Background: Myocardial disease is an important component of the wide field of cardiovascular disease. However, the phenomenon of multiple myocardial diseases in a single patient remains understudied.
Aim: To investigate the prevalence and impact of myocarditis in patients with genetic cardiomyopathies and to evaluate the outcomes of myocarditis treatment in the context of cardiomyopathies.
Epicardial Ablation for Arrhythmogenic Disorders in Patients with Brugada Syndrome.

Clinical and Rehabilitation Cardiology Division, San Filippo Neri Hospital, 00135 Rome, Italy.
Brugada syndrome (BrS) is an inherited arrhythmogenic disorder characterized by distinct electrocardiographic patterns and an increased risk of sudden cardiac death due to ventricular arrhythmias. Effective management of BrS is essential, particularly for high-risk patients with recurrent arrhythmias. While implantable cardioverter-defibrillator (ICD) is effective in terminating life-threatening arrhythmias, it does not prevent arrhythmia onset and can lead to complications such as inappropriate shocks.

Background: Resistance to lenvatinib poses a serious threat to the therapy of patients with Hepatocellular Carcinoma (HCC). The mechanism by which HCC develops resistance to lenvatinib is currently unknown.
Objective: The aim of this study was to identify key genes and pathways involved in lenvatinib resistance in HCC using bioinformatic analysis and experimental validation.
Coexistence of cardiac sarcoidosis and arrhythmogenic cardiomyopathy-associated genetic variants: a multicentre case-control study.
Heart
January 2025
Department of Cardiology, University Hospital Zurich, Zurich, Switzerland
Background: Cardiac sarcoidosis (CS) is a chronic inflammatory disease characterised by non-caseating granulomas, while arrhythmogenic cardiomyopathy (ACM) is a genetic condition mainly affecting desmosomal proteins. The coexistence of CS and genetic variants associated with ACM is not well understood, creating challenges in diagnosis and management. This study aimed to describe the clinical, imaging and genetic features of patients with both conditions.
