Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia (ARVC/D) - What We Have Learned after 40 Years of the Diagnosis of This Clinical Entity.

Arq Bras Cardiol 2019 Jan;112(1):91-103

'Unité de Rythmologie de l'Institut de Cardiologie de l'Hôpital Pitié-Salpêtrière, Paris - France.

Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) was initially recognized as a clinical entity by Fontaine and Marcus, who evaluated a group of patients with ventricular tachyarrhythmia from a structurally impaired right ventricle (RV). Since then, there have been significant advances in the understanding of the pathophysiology, manifestation and clinical progression, and prognosis of the pathology. The identification of genetic mutations impairing cardiac desmosomes led to the inclusion of this entity in the classification of cardiomyopathies. Read More

Hemodynamic Changes in the Right Ventricle Induced by Variations of Cardiac Output: A Possible Mechanism for Arrhythmia Occurrence in the Outflow Tract.

Sci Rep 2019 Jan 14;9(1):100. Epub 2019 Jan 14.

University Heart Center, Department of Cardiology, Zurich, 8091, Switzerland.

The rationale of this paper is to investigate right ventricular (RV) hemodynamics in relation to changes in cardiac output, and in particular to study exercise-induced stresses at the RV outflow tract (RVOT), which is a common site of ventricular arrhythmias in the athlete's heart. We hypothesize that the thin-walled RVOT is exposed to high wall shear stresses (WSS) during physiological states associated with high cardiac output such as exercise, and therefore, may be particularly prone to substrate formation leading to ventricular tachyarrhythmias. 3D Particle Tracking Velocimetry (3D-PTV), an optical imaging method, has been performed in a novel anatomically accurate compliant silicone right heart model derived from a high resolution MRI heart scan of a healthy male proband.

Arrhythmogenic Cardiomyopathy in 2018-2019: ARVC/ALVC or Both?

Heart Lung Circ 2019 Jan 24;28(1):164-177. Epub 2018 Oct 24.

Department of Cardiology, Westmead Applied Research Centre, Westmead Hospital, University of Sydney, Sydney, NSW, Australia. Electronic address:

Arrhythmogenic cardiomyopathy (ACM) is now commonly used to describe any form of non-hypertrophic, progressive cardiomyopathy characterised by fibrofatty infiltration of the ventricular myocardium. Right ventricular (RV) involvement refers to the classical arrhythmogenic right ventricular cardiomyopathy, but left ventricular, or bi-ventricular involvement are now recognised. ACM is mostly hereditary and associated with mutations in genes encoding proteins of the intercalated disc. Read More

Cardiac magnetic resonance based deformation imaging: role of feature tracking in athletes with suspected arrhythmogenic right ventricular cardiomyopathy.

Int J Cardiovasc Imaging 2019 Mar 31;35(3):529-538. Epub 2018 Oct 31.

Heart and Vascular Center, Semmelweis University, Budapest, Hungary.

Both, arrhythmogenic right ventricular cardiomyopathy (ARVC) and regular training are associated with right ventricular (RV) remodelling. Cardiac magnetic resonance (CMR) is given an important role in the diagnosis of ARVC in current task force criteria (TFC), however, they contain no cut-off values for athletes. We aimed to confirm the added value of feature tracking and to provide new cut-off values to differentiate between ARVC and athlete's heart. Read More

Right bundle branch block and conduction disturbances in Brugada syndrome and arrhythmogenic right ventricular cardiomyopathy.

J Interv Card Electrophysiol 2018 Aug 26;52(3):307-313. Epub 2018 May 26.

Cardiology Division, Policlinico Casilino, Via Casilina 1049, 00169, Rome, Italy.

Right bundle branch block is relatively frequent in the general population and is generally considered benign in healthy individuals. However, it has been associated with increased cardiovascular risk and all-cause mortality in various cohort studies. Indeed, the presence of right bundle branch block in subjects affected by cardiomyopathies or channelopathies is not rare and may conceal underlying electrocardiographic changes, thus making the diagnosis of such conditions more challenging.

Diagnostic Criteria, Genetics, and Molecular Basis of Arrhythmogenic Cardiomyopathy.

Heart Fail Clin 2018 Apr;14(2):201-213

Department of Cardiac, Thoracic, and Vascular Sciences, University of Padova Medical School, Padova, Italy.

Arrhythmogenic cardiomyopathy (AC) is an inherited heart muscle disease characterized by myocardial atrophy and fibrofatty replacement of the ventricular myocardium, at risk of sudden cardiac death, particularly in the young and athletes. Because there is no "gold standard" to reach the diagnosis of AC, multiple categories of diagnostic information have been combined, including imaging, electrocardiographic changes, arrhythmias, tissue characterization, and family history. However, the routine use of contrast-enhanced cardiac magnetic resonance increasingly revealed left dominant AC, a variant that is not well addressed in the diagnostic criteria and still escapes clinical identification.

Department of Radiological, Oncological and Anatomo-Pathological Sciences, Policlinico Umberto I, Sapienza University of Rome, Viale Regina Elena 324, 00161 Rome, Italy.

Ectopic cardiac fatty images are not rarely detected incidentally by computed tomography and cardiac magnetic resonance, or by exams focused on the heart as in general thoracic imaging evaluations. A correct interpretation of these findings is essential in order to recognize their normal or pathological meaning, focusing on the eventually associated clinical implications. The development of techniques such as computed tomography and cardiac magnetic resonance allowed a detailed detection and evaluation of adipose tissue within the heart. Read More

Coupling interval variability of premature ventricular contractions in patients with different underlying pathology: an insight into the arrhythmia mechanism.

J Interv Card Electrophysiol 2018 Jan 5;51(1):25-33. Epub 2018 Jan 5.

Department of Cardiology, Electrophysiology, Erasmus Medical Center, Rotterdam, The Netherlands.

Purpose: Coupling interval (CI) variability of premature ventricular contractions (PVCs) is influenced by the underlying arrhythmia mechanism. The aim of this study was to compare CI variability of PVCs in different myocardial disease entities, in order to gain insight into their arrhythmia mechanism.

Methods: Sixty-four patients with four underlying pathologies were included: idiopathic (n = 16), non-ischemic dilated cardiomyopathy (NIDCM) (n = 16), familial cardiomyopathy (PLN/LMNA) (n = 16), and post-MI (n = 16)-associated PVCs. Read More

Right ventricular remodeling in athletes and in arrhythmogenic cardiomyopathy.

Scand Cardiovasc J 2018 Feb 19;52(1):13-19. Epub 2017 Dec 19.

a Institute of Emergency for Cardiovascular Diseases "Prof.dr.C.C.Iliescu" , University of Medicine and Pharmacy "Carol Davila" Bucharest , Bucharest , Romania.

Objective: Changes in right ventricular (RV) structure and function following prolonged endurance training in athletes arise due to its unique anatomy and physiology. Arrhythmogenic cardiomyopathy (AC) should be differentiated from electrical, functional and structural adaptation of the heart in response to repetitive intense physical activity due to the negative contribution of exercise on AC progression and arrhythmic risk.

Design: For this review we performed a systematic search of the PubMed database up to October 2017 using terms and keywords pertaining to RV, athlete's heart (AH), AC, sudden cardiac death. Read More

Isolated Cardiac Sarcoidosis Mimicking Arrhythmogenic Right Ventricular Cardiomyopathy.

Intern Med 2018 Mar 8;57(6):835-839. Epub 2017 Dec 8.

Division of Cardiovascular Medicine, Department of Medicine, Jichi Medical University School of Medicine, Japan.

The diagnosis of cardiac sarcoidosis (CS) has become easier due to advances in imaging modalities, but we sometimes encounter difficult-to-diagnose patients. We herein report the case of a 60-year-old Japanese woman who was diagnosed with isolated CS, although she also met the diagnostic criteria of arrhythmogenic right ventricular cardiomyopathy (ARVC). A histological examination by an endomyocardial biopsy of the right ventricle revealed the typical findings of granulomatous change for CS. 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.

Exercise and the right ventricle: a potential Achilles' heel.

Cardiovasc Res 2017 Oct;113(12):1499-1508

Department of Cardiovascular Sciences, KU Leuven, Leuven, Belgium.

Exercise is associated with unequivocal health benefits and results in many structural and functional changes of the myocardium that enhance performance and prevent heart failure. However, intense exercise also presents a significant hemodynamic challenge in which the right-sided heart chambers are exposed to a disproportionate increase in afterload and wall stress that can manifest as myocardial fatigue or even damage if intense exercise is sustained for prolonged periods. This review focuses on the physiological factors that result in a disproportionate load on the right ventricle during exercise and the long-term consequences. Read More

Combining computer modelling and cardiac imaging to understand right ventricular pump function.

Cardiovasc Res 2017 Oct;113(12):1486-1498

CARIM School for Cardiovascular Diseases, Maastricht University Medical Center, Maastricht, The Netherlands.

Right ventricular (RV) dysfunction is a strong predictor of outcome in heart failure and is a key determinant of exercise capacity. Despite these crucial findings, the RV remains understudied in the clinical, experimental, and computer modelling literature. This review outlines how recent advances in using computer modelling and cardiac imaging synergistically help to understand RV function in health and disease. Read More

Arrhythmogenic Cardiomyopathy.

Circ Res 2017 Sep;121(7):784-802

From the Department of Cardiac, Thoracic, and Vascular Sciences, University of Padova Medical School, Italy (D.C., C.B.); and Department of Medicine/Cardiology, Center for Inherited Heart Disease, Johns Hopkins University School of Medicine, Baltimore, MD (D.P.J.).

Arrhythmogenic cardiomyopathy is an inherited heart muscle disorder, predisposing to sudden cardiac death, particularly in young patients and athletes. Pathological features include loss of myocytes and fibrofatty replacement of right ventricular myocardium; biventricular involvement is often observed. It is a cell-to-cell junction cardiomyopathy, typically caused by genetically determined abnormalities of cardiac desmosomes, which leads to detachment of myocytes and alteration of intracellular signal transduction.

Arrhythmogenic Right Ventricular Cardiomyopathy in an Endurance Athlete Presenting with Ventricular Tachycardia and Normal Right Ventricular Function.

Tex Heart Inst J 2017 Aug 1;44(4):290-293. Epub 2017 Aug 1.

Arrhythmogenic right ventricular cardiomyopathy, a genetically inherited disease that results in fibrofatty replacement of normal cardiac myocytes, has been associated with sudden cardiac death in athletes. Long-term participation in endurance exercise hastens the development of both the arrhythmic and structural arrhythmogenic right ventricular cardiomyopathy phenotypes. We describe the unusual case of a 34-year-old, symptomatic, female endurance athlete who had arrhythmogenic right ventricular cardiomyopathy in the presence of a structurally normal right ventricle.

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

Isolated Late Activation Detected by Magnetocardiography Predicts Future Lethal Ventricular Arrhythmic Events in Patients With Arrhythmogenic Right Ventricular Cardiomyopathy.

Circ J 2017 12 30;82(1):78-86. Epub 2017 Aug 30.

Department of Cardiovascular Medicine, National Cerebral and Cardiovascular Center.

Background: Risk stratification of ventricular arrhythmias is vital to the optimal management in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). We hypothesized that 64-channel magnetocardiography (MCG) would be useful to detect isolated late activation (ILA) by overcoming the limitations of conventional noninvasive predictors of ventricular tachyarrhythmias, including epsilon waves, late potential (LP), and right ventricular ejection fraction (RVEF), in ARVC patients.Methods and Results:We evaluated ILA on MCG, defined as discrete activations re-emerging after the decay of main RV activation (%magnitude >5%), and conventional noninvasive predictors of ventricular tachyarrhythmias (epsilon waves, LP, and RVEF) in 40 patients with ARVC.
