Abstract
Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) is an inherited myocardial disease characterized by fibro-fatty replacement of the right ventricular myocardium, and associated with paroxysmal ventricular arrhythmias and sudden cardiac death (SCD). It is currently the second most common cause of SCD after hypertrophic cardiomyopathy in young people <35 years of age, causing up to 20% of deaths in this patient population. This condition has a male preponderance and is more commonly found in individuals of Italian and Greek descent. To date, there is no single diagnostic test for ARVC/D and the diagnosis is made based on clinical, electrocardiographic, and radiological findings according to the Revised 2010 Task Force Criteria. In this review, we will discuss the mainstay treatment which includes pharmacotherapy, implantable cardioverter-defibrillator insertion for abortion of sudden cardiac death, and in the advanced stages of the disease cardiac transplantation.

Abstract
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a crucial health problem. With sudden death often being the first presentation, early diagnosis for ARVC is essential. Up to date, electrocardiogram (ECG) is a widely used diagnostic method without invasive harms. To diagnose and treat ARVC as well as possible, we should clearly elucidate its pathophysiological alterations. A 66-year-old farmer presented to the Emergency Department with continuous palpitation, chest tightness, profuse sweating, and nausea with no obvious predisposing causes. An ECG indicated ventricular tachycardia (VT). The patient experienced a sudden drop in blood pressure and acute confusion. After an immediate electrical conversion, his consciousness was gradually restored, and symptoms relieved. The patient was then transferred to the Department of Cardiology to receive ECG, echocardiography, coronary angiogram, biochemical assays, endocardiac tracing, and radiofrequency ablation. In the end, he was diagnosed with ARVC, evidenced by bilateral ventricle dilation and epsilon waves in leads V1-V3. Appropriate therapies were provided for this patient including pharmacological intervention and radiofrequency ablation. Although the diagnosis of ARVC is not difficult, this patient's ECG manifested several interesting features and should be further investigated: T wave inversions were found extensively in the anterior and inferior leads, revealing the involvement of bilateral ventricles; VTs with different morphologies and cycle lengths were found, and some VTs manifested the feature of irregularly irregular rhythm, reminding us to carefully differentiate some special VTs from atrial fibrillation (AF); and epsilon waves gradually appeared in leads V1-V3 and avR since the onset of ARVC. Most importantly, the epsilon waves behind QRS complex appeared in both sinus rhythm and ventricular premature beats/VT originating from cardiac apex, whereas the epsilon waves prior to QRS complex occurred in VT originating from right ventricular outflow tract (RVOT). The features of T wave inversion and epsilon wave in ECGs and the appearance of VTs with different morphologies can reflect the progression of ARVC. The position relationship between epsilon wave and QRS complex in VT depends on ventricular activation sequence, that is, the localization of epsilon wave depends on where VT is originating from.

Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy in the Pediatric Population: Clinical Characterization and Comparison With Adult-Onset Disease. JACC Clin Electrophysiol 2015; 1:551-560. [PMID: 29759408 DOI: 10.1016/j.jacep.2015.08.004] [Citation(s) in RCA: 60] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2015] [Revised: 07/27/2015] [Accepted: 08/20/2015] [Indexed: 11/15/2022]
Abstract
OBJECTIVES The aims of this study were to determine the clinical characteristics and outcomes of pediatric-onset arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) and to compare these with those of adult-onset ARVD/C. BACKGROUND Improved early detection and increased awareness of ARVD/C have led to a growing group of pediatric patients seeking management recommendations. Prior studies have mainly included adults with ARVD/C; however, clinical features and outcomes may differ in pediatric subjects. METHODS Among 502 subjects fulfilling task force criteria for ARVD/C, we identified 75 (15%) with pediatric-onset disease (diagnosis at <18 years of age or probands presenting symptomatically at <18 years of age). Clinical characteristics and outcomes (sustained ventricular tachycardia, cardiac transplantation, and death) were compared between pediatric and adult patients. RESULTS Pediatric patients presented at 15.3 ± 2.4 years of age. Most pediatric patients were male (55%) and ARVD/C-associated mutation carriers (80%). One-fourth of pediatric patients presented with sudden cardiac death (15%) or resuscitated sudden cardiac arrest (11%). Compared with adults, pediatric patients were disproportionately mutation carriers (p = 0.002) but not more often male (p = 0.696) or probands (p = 0.371). Pediatric patients were more likely to present with sudden cardiac death (p = 0.003), whereas adults more often presented with sustained ventricular tachycardia (p = 0.017). There were no other phenotypic differences between the groups. During 8.4 ± 7.5 years of follow-up, survival free from sustained ventricular tachycardia (p = 0.359), cardiac transplantation (p = 0.523), and death (p = 0.359) was similar between pediatric and adult patients. CONCLUSIONS Pediatric patients with ARVD/C are typically male mutation carriers presenting in adolescence. Pediatric patients disproportionately present with sudden cardiac death. However, once diagnosed, clinical characteristics and outcomes are similar between pediatric and adult patients.
