Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia

Indian Pacing and Electrophysiology Journal, 2003
Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is characterized by the patchy replacement of myocardium by fatty or fibrofatty tissue.

Age‐ and sex‐specific modulation of human cardiac electrophysiology by doxorubicin

The Journal of Physiology, EarlyView.
Abstract figure legend DOX differentially impacts cardiac electrophysiology based on sex and age. Sex differences were primarily observed among younger hearts, where action potential duration (APD) prolongation was observed in females, but not in males. Created using BioRender. George, S. (2026) https://BioRender.com/wresf1k Abstract Acute doxorubicin (

Pulmonary embolism and ventricular tachycardia as the first symptoms of arrhythmogenic right ventricular cardiomyopathy in a 71-year-old woman

Folia Cardiologica
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetically predisposed form of cardiomyopathy. The pathogenesis of ARVC involves structural and functional changes in the myocardium, particularly in the right ventricle, leading to its ...

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

The Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

A late-onset arrhythmogenic right ventricular cardiomyopathy unveiled by supraventricular tachycardia: Case report

Radiology Case Reports
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare myocardial genetic disease that leads to heart failure and sudden cardiac death. The diagnosis of ARVC remains challenging given its variable presentation.

High‐Density Spectral Analysis for Bi‐Atrial Arrhythmogenic Substrate During Non‐Paroxysmal Atrial Fibrillation

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
Analyzing 48 153 CARTOFINDER mapping points revealed that both FoA and RoA sites demonstrated elevated DF deviation (DFD) and RI compared to non‐sites. While both metrics increased progressively with FoA repetitions, high‐repetition RoA sites paradoxically displayed lower values.

PATHOLOGICAL EVIDENCE OF EXTENSIVE LEFT-VENTRICULAR INVOLVEMENT IN ARRHYTHMOGENIC RIGHT VENTRICULAR CARDIOMYOPATHY

, 1992
Arrhythmogenic right ventricular cardiomyopathy (also known as arrhythmogenic right ventricular dysplasia) is characterized by adipose or fibroadipose tissue replacement of the right ventricular myocardium, whereas the left ventricle is substantively ...

Rapid progression of right ventricular dysfunction: a case report

BMC Cardiovascular Disorders
Background Arrhythmogenic cardiomyopathy (ACM) is a genetic myocardial disease characterized by progressive myocyte loss and fibrofatty (fibrous and adipose) tissue replacement to predispose these patients to fatal ventricular arrhythmias and impairment ...

Mouse models in Arrhythmogenic Right Ventricular Cardiomyopathy

Frontiers in Physiology, 2012
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a heart muscle disorder characterized by fibrofatty replacement of cardiomyocytes. The cardinal manifestations are arrhythmias, sudden cardiac death and seldom heart failure.

The role of macrophage migration inhibitory factor (MIF) in the pathogenesis and progression of cardiovascular disease

British Journal of Pharmacology, Volume 183, Issue 19, Page 5732-5751, October 2026.
Abstract Cardiovascular disease (CVD) remains the leading global cause of death, driven by complex mechanisms, in which chronic inflammation plays a central role. Inflammatory pathways contribute to all stages of CVD, from endothelial dysfunction and plaque formation to erosion, rupture and myocardial injury.
