AIMS The mechanisms responsible for renal injury in atherosclerotic renovascular disease (ARVD) are incompletely understood, and few therapeutic options are available to reverse it. We hypothesized that chronic renal damage involves mitochondrial injury, and that mitochondrial protection would reduce renal fibrosis and dysfunction in ARVD pigs. METHODS AND RESULTS Domestic pigs were studied a...

OBJECTIVE Among the inherited cardiomyopathies, Arrhythmogenic right ventricular dysplasia/cardiomyopathy is unique with a peculiar pathology of fibro-fatty replacement. Studies have been carried out all over the world and several groups have reported clinical heterogeneity in manifestation of ARVD/C related symptoms. Present study is an attempt to identify the clinical profile of ARVD/C patien...

BACKGROUND The purpose of this study was to systematically study diagnostic and prognostic electrocardiographic (ECG) characteristics of arrhythmogenic right ventricle dysplasia/cardiomyopathy (ARVD/C). METHODS AND RESULTS The patient population included 50 patients with ARVD/C (27 males, 23 females; mean age 38+/-15 years). We also analyzed the ECG of 50 age- and gender-matched normal contro...

OBJECTIVES The purpose of this study was to determine interobserver agreement for interpretation of magnetic resonance imaging (MRI) examinations of arrhythmogenic right ventricular dysplasia (ARVD) and to determine sensitivity and specificity of fat detection versus functional parameters measured by MRI. BACKGROUND The interobserver variability of MRI and the relative importance of different...

Atherosclerotic renovascular disease (ARVD) is a major cause of secondary hypertension, especially in the elderly population. ARVD typically involves the proximal third of the renal artery including the perirenal aorta and ostium. The prevalence of ARVD is about 6.3–6.8 % in patients undergoing angiography or as determined in a population-based study utilizing a noninvasive screening technique ...

Arrhythmogenic right ventricular dysplasia/ /cardiomyopathy (ARVD/C) is a genetically determined heart muscle disorder that is characterized pathologically by fibrofatty replacement of the right ventricular (RV) myocardium. The clinical diagnosis of ARVD/C is complex, since there is no single diagnostic “gold standard”. The diagnosis is based on major and minor criteria that have been modified ...

The ECG is abnormal in most patients with arrhythmogenic right ventricular dysplasia (ARVD). Right ventricular parietal block, reduced QRS amplitude, epsilon wave, T wave inversion in V1-3 and ventricular tachycardia in the morphology of left bundle branch block are the characteristic changes that reflect the underlying genetic predetermined pathology and pathoelectrophysiology. Recognizing the...

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 cathet...

PURPOSE With the increased use of genetic testing for arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C), this disease is being increasingly recognised among elderly patients. However, elderly ARVD/C patients were underrepresented in prior cohorts. We aimed to describe the phenotypical characteristics and outcomes among ARVD/C patients surviving ≥50 years. METHODS We assessed ...

BACKGROUND Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is characterized by frequent life-threatening ventricular arrhythmias, diagnosed on average in the teens to mid-50s and commonly treated by implantable cardioverter defibrillators (ICDs). As younger age and high frequency of ICD discharges are risk factors for difficulties in psychosocial adjustment, we developed a st...
