The classical molecular diagnosis from blood cells fails to identify mutations in around 30% of patients. Probes used for endocardial voltage mapping allow to collect some cardiomyocytes which could be used for DNA analysis.\n\nThe aim of this project is to investigate if cardiomyocytes can efficiently be collected during endocardial voltage mapping in patients with arrhythmogenic right ventricular cardiomyopathy/dysplasia. Thirty patients suffering from arrhythmogenic right ventricular cardiomyopathy/dysplasia cardiac and needing endocardial voltage mapping for disease diagnosis and/or prognosis assessment will be included. The main outcome will be the percentage of patients in whom mapping will allow to collect intact cardiomyocytes from which high quality DNA extraction will be achieved. Other outcomes include the identification of new mutational mechanisms as somatic mosaicism in selected genes (PKP2, DSCG2 DSP) and the feasibility of epigenetic analysis of these genes.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* patients needing endocardial voltage mapping in the context of arrhythmogenic right ventricular cardiomyopathy/dysplasia diagnosed using current criteria\n\nExclusion Criteria:\n\n* Patient under 18 years, pregnant women and patients under legal protection'}, 'identificationModule': {'nctId': 'NCT03177018', 'acronym': 'FA2CM-DVDA', 'briefTitle': 'DNA Analysis From Isolated Cardiomyocytes in the Molecular Diagnosis of Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Toulouse'}, 'officialTitle': 'Feasibility of DNA Analysis From Isolated Cardiomyocytes in the Molecular Diagnosis of Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia', 'orgStudyIdInfo': {'id': 'RC31/15/7731'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Patients with Cardiomyocytes collection', 'description': 'Patients suffering from arrhythmogenic right ventricular cardiomyopathy/dysplasia cardiac and needing endocardial voltage mapping for disease diagnosis and/or prognosis assessment', 'interventionNames': ['Diagnostic Test: Cardiomyocytes collection']}], 'interventions': [{'name': 'Cardiomyocytes collection', 'type': 'DIAGNOSTIC_TEST', 'description': 'collect intact cardiomyocytes from which high quality DNA extraction will be achieved', 'armGroupLabels': ['Patients with Cardiomyocytes collection']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Paris', 'country': 'France', 'facility': 'Cardiology-rytmology service', 'geoPoint': {'lat': 48.85341, 'lon': 2.3488}}, {'zip': '31000', 'city': 'Toulouse', 'country': 'France', 'facility': 'University Hospital Toulouse - Cardiology Department', 'geoPoint': {'lat': 43.60426, 'lon': 1.44367}}], 'overallOfficials': [{'name': 'Philippe MAURY, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University Hospital, Toulouse'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University Hospital, Toulouse', 'class': 'OTHER'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
