Arrhythmogenic right ventricular cardiomyopathy (ARVC) is characterized by progressive fibro-fatty replacement of the myocardium that represents the substrate for recurrent sustained ventricular tachycardia (VT). These arrhythmias characterize the clinical course of a sizeable proportion of patients and have significant implications for their quality of life and long-term prognosis. Antiarrhythmic drugs are often poorly tolerated and usually provide incomplete control of arrhythmia relapses. Catheter ablation is a potentially effective strategy to treat frequent VT episodes and ICD shocks in ARVC patients. The aims of this review are to discuss the electrophysiological and electroanatomic substrates of ventricular tachycardia in patients with ARVC and to analyze the role of catheter ablation in their management with particular reference to selection of patients, technical issues, potential complications and outcomes.

Background : Arrhythmogenic right ventricular cardiomyopathy(ARVC) is an inherited myocardial disease affecting predominantly young people and manifests as sustained ventricular tachycardia, sudden cardiac death (SCD) or heart failure. However, its first manifestation in older patients is infrequent. Diagnosis of ARVC remains a clinical challenge and need further investigation. Our case report investigated role of non invasive modalities for diagnosis of ARVC patient. Case Presentation : A 65 year old man was admitted to the hospital with symptoms of palpitationand near syncope. An Electrocardiogram (ECG) showed a sustained VT with LBBB morphology and inferior axis. The patient was cardioverted to sinus rhytm with a single 100J shock. Postcardioversion ECG showed an epsilon wave in right precordial leads. Echocardiography revealed extensive RV enlargement and reduce function. Our patient had three major (RV aneurysm, epsilon wave and T wave inversion) and one minor criteria (sustained LBBB type-VT with inferior axis)making the diagnosis of ARVC definite according to the revised Task Forced Criteria. Conclusion: ARVC may have a very late presentation and this diagnosis should be considered as a potential cause of sustained VT of RV origin among the elderly. ECG and echocardiography as non invasive modalities have an important role for the diagnosis of patients with suspected ARVC. Keywords :Arrhythmogenic right ventricular cardiomyopathy,ventricular tachycardia, sudden cardiac death, diagnosis.

Introduction: Pericardial fluid is enriched with biologically active molecules of cardiovascular origin including microRNAs. Investigation of the disease-specific extracellular microRNAs could shed light on the molecular processes underlying disease development. Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart disease characterized by life-threatening arrhythmias and progressive heart failure development. The current data about the association between microRNAs and ARVC development are limited.Methods and Results: We performed small RNA sequence analysis of microRNAs of pericardial fluid samples obtained during transcutaneous epicardial access for ventricular tachycardia (VT) ablation of six patients with definite ARVC and three post-infarction VT patients. Disease-associated microRNAs of pericardial fluid were identified. Five microRNAs (hsa-miR-1-3p, hsa-miR-21-5p, hsa-miR-122-5p, hsa-miR-206, and hsa-miR-3679-5p) were found to be differentially expressed between patients with ARVC and patients with post-infarction VT. Enrichment analysis of differentially expressed microRNAs revealed their close linkage to cardiac diseases.Conclusion: Our data extend the knowledge of pericardial fluid microRNA composition and highlight five pericardial fluid microRNAs potentially linked to ARVC pathogenesis. Further studies are required to confirm the use of pericardial fluid RNA sequencing in differential diagnosis of ARVC.
