Diagnostic Challenges in Rare Causes of Arrhythmogenic Cardiomyopathy-The Role of Cardiac MRI.

J Pers Med 2022 Jan 31;12(2). Epub 2022 Jan 31.

Department of Cardiovascular and Thoracic Surgery, "Iuliu Hatieganu" University of Medicine and Pharmacy Cluj Napoca, 8, Victor Babes, St., 400012 Cluj-Napoca, Romania.

Arrhythmogenic right ventricular dysplasia (ARVD) is a rare genetic condition of the myocardium, with a significantly high risk of sudden death. Recent genetic research and improved understanding of the pathophysiology tend to change the ARVD definition towards a larger spectrum of myocardial involvement, which includes, in various proportions, both the right (RV) and left ventricle (LV), currently referred to as ACM (arrhythmogenic cardiomyopathy). Its pathological substrate is defined by the replacement of the ventricular myocardium with fibrous adipose tissue that further leads to inadequate electrical impulses and translates into varies degrees of malignant ventricular arrythmias and dyskinetic myocardium movements.

J Cardiovasc Magn Reson 2021 05 20;23(1):58. Epub 2021 May 20.

The Russell H. Morgan Department of Radiology and Radiological Sciences, Johns Hopkins University School of Medicine, 600 N. Wolfe St.; Halsted B180, Baltimore, MD, USA.

Background: Left ventricular (LV) fibrofatty infiltration in arrhythmogenic right ventricular (RV) dysplasia/cardiomyopathy (ARVD/C) has been reported, however, detailed cardiovascular magnetic resonance (CMR) characteristics and association with outcomes are uncertain. We aim to describe LV findings on CMR in ARVD/C patients and their relationship with arrhythmic outcomes.

Methods: CMR of 73 subjects with ARVD/C according to the 2010 Task Force Criteria (TFC) were analyzed for LV involvement, defined as ≥ 1 of the following features: LV wall motion abnormality, LV late gadolinium enhancement (LGE), LV fat infiltration, or LV ejection fraction (LVEF) < 50%. Read More

Epicardial Ablation of Ventricular Tachycardia in Arrhythmogenic Right Ventricular Cardiomyopathy.

Card Electrophysiol Clin 2020 09 8;12(3):329-343. Epub 2020 Jul 8.

ARVC Program, Division of Cardiology, Johns Hopkins University School of Medicine, Baltimore, MD, USA.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart muscle disease characterized by progressive fibrofatty replacement of the myocardium, right ventricular enlargement, and malignant ventricular arrhythmias. Ventricular tachycardia (VT) may be seen in all stages of the disease and is associated with sudden cardiac death. In patients who failed anti-arrhythmic medical therapy, catheter ablation has become an attractive therapeutic option to reduce VT burden and implantable cardioverter-defibrillator interventions.

Transesophageal and intracardiac ultrasound in arrhythmogenic right ventricular dysplasia/cardiomyopathy: Two case reports.

Medicine (Baltimore) 2020 Apr;99(15):e19817

5th Department of Internal Medicine, Cardiology-Rehabilitation.

Rationale: Two-dimensional echocardiography (2D echo) is a major tool for the diagnosis of Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). However 2D echo can skip regional localized anomalies of the right ventricular wall. We aimed to determine whether transesophageal and intracardiac ultrasound can provide additional information, on the right ventricular abnormalities compared to 2D echo. Read More

APHP, Pitié-Salpêtrière University Hospital, Institute of Cardiology, Paris, France; Centre de Référence des Maladies Cardiaques Héréditaires, Paris, France; Institute of Cardiometabolism and Nutrition (ICAN), Paris, France.

Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is an inherited cardiomyopathy that can lead to sudden cardiac death and heart failure. Our understanding of its pathophysiology and clinical expressivity is continuously evolving. The diagnosis of ARVC/D remains particularly challenging due to the absence of specific unique diagnostic criteria, its variable expressivity, and incomplete penetrance. Read More

Service Rythmologie, Hôpital Cardiologique Louis Pradel, Hospices Civils de Lyon, Lyon, France.

Arrhythmogenic right ventricular dysplasia (ARVD) is a rare cardiomyopathy characterized by the progressive replacement of cardiomyocytes by fatty and fibrous tissue in the right ventricle (RV). These infiltrations lead to cardiac electrical instability and ventricular arrhythmia. Current treatment for ARVD is empirical and essentially based on treatment of arrhythmia. Read More

Intracardiac ultrasound to detect aneurysm in arrhythmogenic right ventricular dysplasia/cardiomyopathy.

Oxf Med Case Reports 2018 Jan 25;2018(1):omx088. Epub 2018 Jan 25.

Cardiology-Rehabilitation, 5th Department of Internal Medicine, 'Iuliu Hatieganu' University of Medicine and Pharmacy, Cluj-Napoca, Romania.

Arrhythmogenic right ventricular dysplasia/cardiomyopathy is a genetic disorder characterized by fibrofattty replacement of the right ventricular myocardium. In the revised 2010 Task Force Criteria, a major criteria for ARVD/C is the presence of RV aneurysm by 2D echo. Our report demonstrates that intracardiac ultrasound can detect RV aneurysms and also focal absence of trabeculations which brings additional value to the diagnosis of ARVD/C. Read More

Epicardial ablation of ventricular tachycardia in a patient with arrhythmogenic right ventricular dysplasia after failed conventional endocardial ablation: A case for remote navigation with functional image integration.

Glob Cardiol Sci Pract 2016 Dec 30;2016(4):e201639. Epub 2016 Dec 30.

Department of Cardiology, University of Bristol, Bristol, UK.

Arrhythmogenic right ventricular dysplasia (ARVD) is an inheritable heart muscle disease that predominantly affects the right ventricle (RV) and predisposes to ventricular arrhythmias and sudden cardiac death (SCD). The natural history is predominantly related to ventricular electric instability which may lead to arrhythmic SCD, mostly in young people and athletes, but may progress with significant RV muscle disease and left-ventricular (LV) involvement and can result in right or biventricular heart failure. We report on a 54-year-old male with ARVD who underwent an epicardial ventricular tachycardia (VT) ablation using remote magnetic navigation (RMN) after functional imaging from a nuclear perfusion study was fused with a 3D segmentation from computed tomography (CT) imaging.

Feature tracking CMR reveals abnormal strain in preclinical arrhythmogenic right ventricular dysplasia/ cardiomyopathy: a multisoftware feasibility and clinical implementation study.

J Cardiovasc Magn Reson 2017 Sep 1;19(1):66. Epub 2017 Sep 1.

Department of Medicine, Division of Cardiology, University Medical Center Utrecht, Utrecht, the Netherlands.

Background: Regional right ventricular (RV) dysfunction is the hallmark of Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C), but is currently only qualitatively evaluated in the clinical setting. Feature Tracking Cardiovascular Magnetic Resonance (FT-CMR) is a novel quantitative method that uses cine CMR to calculate strain values. However, most prior FT-CMR studies in ARVD/C have focused on global RV strain using different software methods, complicating implementation of FT-CMR in clinical practice. Read More

Utility of speckle tracking echocardiography imaging in patients with asymptomatic and symptomatic arrhythmogenic right ventricular cardiomyopathy.

Echocardiography 2016 Nov 7;33(11):1683-1688. Epub 2016 Sep 7.

Cardiology Department, Kartal Kosuyolu Heart Research and Training Hospital, Istanbul, Turkey.

Background: Arrhythmogenic right ventricular dysplasia (ARVD) is characterized by the progressive replacement of ventricular myocytes with variable amounts of fibrous and adipose tissue. Several studies have suggested that speckle tracking echocardiographic (STE) parameters such as strain (S) and strain rate (SR) may prove useful in the early detection of right ventricular (RV) dysfunction. Therefore, the aim of this study was to evaluate RV myocardial function using the STE method in both asymptomatic and symptomatic patients with ARVD and to assess its potential role in the differential diagnosis of these two presentations.
