Arvd, arvc, "arrhythmogenic right ventricular dysplasia"

Rajeev K Pathak, Fermin C Garcia
Endocardial and epicardial electroanatomical mapping and ablation is a safe and effective therapy in the treatment of right ventricle arrhythmias occurring in the setting of arrhythmogenic right ventricular cardiomyopathy (ARVD). Careful mapping and ablation plans must be tailored for each patient based on comorbidities and ventricular tachycardia morphologies. This review focuses on the catheter ablation for ventricular arrhythmias in patients with ARVD.

BACKGROUND: Arrhythmogenic right ventricular dysplasia (ARVD) is characterized by progressive replacement of ventricular myocytes with variable amounts of fibrous and adipose tissue. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. The aim of this study was to evaluate repolarization dispersion measured from the 12-lead surface electrocardiogram (including Tp-e interval, Tp-e/QT, and Tp-e/QTc ratio) in asymptomatic ARVD patients METHODS: We selected 27 patients with asymptomatic ARVD and 27 age- and gender-match young, healthy volunteers...

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...

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is an inherited cardiomyopathy characterised by frequent ventricular arrhythmias and slowly progressive predominant RV dysfunction. Up to two-thirds of ARVD/C patients have mutations in genes encoding the cardiac desmosome. Mutations in other genes are increasingly recognised. Inheritance of ARVD/C is generally autosomal dominant with reduced age-related penetrance and significant variable expressivity. While the full explanation for this phenotypic heterogeneity remains unclear, there is increasing evidence that exercise plays a major role in disease penetrance and arrhythmic risk...

INTRODUCTION: Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is characterized by high incidence of ventricular arrhythmias. Overt ARVD/C is preceded by a subclinical stage with lack of detectable ECG and structural abnormalities. Activation delay is present before structural abnormalities and is a hallmark of arrhythmogenesis. Deformation imaging may unmask activation delay in the subclinical stage. METHODS: Three groups were compared: (1) mutation-positive definite ARVD/C-patients fulfilling 2010 Task Force criteria (TFC) (n = 44); (2) asymptomatic mutation carriers not fulfilling TFC and without history of ventricular arrhythmias (n = 31); and (3) controls (n = 30)...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart muscle disease that predisposes to the occurrence of ventricular arrhythmias and sudden death, particularly in the young and athlete. The classic variant of the disease predominantly affects the right ventricle, but phenotypic variants with early and prevalent left ventricular involvement ("left-dominant" ARVC) have also been described, supporting the concept that arrhythmogenic cardiomyopathy is a disease of both ventricles. The diagnosis is multiparametric and is based on a series of criteria, including ECG abnormalities, arrhythmic manifestations, morpho-functional abnormalities and genetic defects...

Arrhythmogenic right ventricular dysplasia (ARVD) is a progressive condition with the right ventricular myocardium being replaced by fibrofatty tissue. It is a hereditary disorder mostly caused by desmosome gene mutations. The prevalence of arrhythmogenic right ventricular cardiomyopathy is about 1/1000-5000. Clinical presentation is usually related to ventricular tachycardias, syncope, presyncope or ventricular fibrillation leading to cardiac arrest, mostly in young people and athletes. We report a case of a 17-year-old boy from Turkey, who was referred to our cardiology department for an ECG, required of him prior to joining a football team...

We describe a 47-year-old man who underwent heart transplantation (HT) for severe right-sided heart failure and periodic episodes of ventricular tachycardia (VT) 43 years after operative repair of tetralogy of Fallot (T of F). The right-ventricular outflow tract, the site where a patch had been placed 4 decades earlier, was aneurysmal. Such development decades after operative repair of T of F of both aneurysm and episodes of VT is probably more common than previously realized.

AIMS: The concealed phase of arrhythmogenic right ventricular cardiomyopathy (ARVC) may initially manifest electrophysiologically. No studies have examined dynamic conduction/repolarization kinetics to distinguish benign right ventricular outflow tract ectopy (RVOT ectopy) from ARVC's early phase. We investigated dynamic endocardial electrophysiological changes that differentiate early ARVC disease expression from RVOT ectopy. METHODS: 22 ARVC (12 definite based upon family history and mutation carrier status, 10 probable) patients without right ventricular structural anomalies underwent high-density non-contact mapping of the right ventricle...

BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is associated with sudden cardiac death. However, the selection of patients for implanted cardioverter-defibrillators (ICDs), as well as programming of the ICD, is unclear. OBJECTIVES: The objective of this study was to identify predictors, characteristics, and treatment of ventricular arrhythmias in patients with ARVC. METHODS: The Multidisciplinary Study of Right Ventricular Cardiomyopathy established the North American ARVC Registry and enrolled patients with a diagnosis of ARVC...

BACKGROUND: Although the Task Force Criteria for arrhythmogenic right ventricular cardiomyopathy (ARVC) have recently been updated, the diagnosis remains challenging in the early stages. The aim of this study was to evaluate the diagnostic value of β-adrenergic stimulation in ARVC. METHODS AND RESULTS: We evaluated 412 consecutive patients (213 men, age 41.5±16 years) referred for premature ventricular contractions evaluation or suspected ARVC. Isoproterenol testing was performed with continuous infusion of isoproterenol (45 μg/min) for 3 minutes...

BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a cardiac disease characterized by the presence of fibrofatty replacement of the right ventricular myocardium, which may cause ventricular arrhythmias and sudden cardiac death. Pathogenic mutations in several genes encoding mainly desmosomal proteins have been reported. Our aim is to perform genotype-phenotype correlations to establish the diagnostic value of genetics and to assess the role of mutation type in age-related penetrance in ARVC...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is predominantly a genetically determined heart muscle disorder that is characterized by fibro-fatty replacement of the right ventricular (RV) myocardium.(1)) The clinical spectrum of ARVC may represent from asymptomatic premature ventricular complexes to ventricular tachycardia (VT) and sudden cardiac death (SCD). It is a well-known leading cause of SCD in young adults.(2,3))There is no general consensus on the management of ARVC in pregnancy, and the preferred mode of delivery is uncertain...

A 55-year-old woman with a history of complete heart block, atrial flutter, and progressive right ventricular failure was referred to our tertiary care center to be evaluated for cardiac transplantation. The patient's clinical course included worsening right ventricular dysfunction for 3 years before the current evaluation. Our clinical findings raised concerns about arrhythmogenic right ventricular cardiomyopathy. Noninvasive imaging, including a positron emission tomographic scan, did not reveal obvious myocardial pathologic conditions...

Sudden death is often the first manifestation in inherited cardiac arrhythmia syndromes. Patients with long QT syndrome who have an episode of syncope while on beta-blockade should be offered an implantable cardioverter-defibrillator (ICD). In Brugada syndrome and hypertrophic cardiomyopathy, ICDs are often the most effective treatment of primary and secondary prevention of cardiac arrest. Risk stratification is crucial in identifying those at greatest risk to provide lifesaving therapy with an ICD while avoiding complications in those unlikely to receive benefit...

Arrhythmogenic right ventricular cardiomyopathy/dysplasia is an inherited cardiomyopathy that is transmitted in autosomal dominant and autosomal recessive forms and involves mutations in desmosomal and extradesmosomal genes. We present a case of arrhythmogenic right ventricular cardiomyopathy that cosegregates in a Lebanese family with a previously unreported desmocollin-2 mutation (c.712_714delGAT). We believe this newly described genetic variant displays autosomal recessive inheritance without the cutaneous manifestations expected in recessive genotypes, and represents the latest addition to the compendium of desmosomal mutations with pathogenic potential...
