The first trans-radial access for cardiovascular diagnostics dates to 1947.\n\nIn 1989, the first case series of 100 coronary angiographies performed through the radial access, demonstrating the safety and the fast mobilization of patients with the radial approach .\n\nThe main advantages of the radial approach are increased safety and comfort of the patients with reduction of bleeding complications and immediate post-procedure ambulation .with these advantages, current guidelines highly recommend radial access for coronary angiography and percutaneous coronary intervention.\n\nMost clinical trials focused solely on the right radial approach and rarely consider the left radial approach. Indeed, the RRA has technical obstacles related to anatomy and clinical practice like increased incidence of tortuosity of the subclavian artery and radial-ulnar artery loop with the right radial approach.\n\nMost operators use the right radial access as the left radial access increase operator discomfort during vascular access and procedure, especially in obese patients.\n\nHowever, the left radial access has potential benefits for both the patient and operator. One of which is that the left radial approach is associated with lower fluoroscopy time compared with the right radial approach.\n\nLeft radial artery as well is an appropriate alternative access for coronary catheterization with less anatomical variations like tortuosity than the right radial artery Moreover, left radial access is preferred for right handed patients because of temporary post-procedural disability caused by hemostasis process in right radial artery access Also subclavian artery tortuosity is significantly more common on the right side and is an important cause of difficult, prolonged, or failed radial procedure.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '110 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients undergoing coronary angiography or elective PCI in assiut university heart hospital.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* • All patients presented to assiut university cardiac catheterization laboratory and eligible for radial coronary procedures (either diagnostic or interventional )\n\nExclusion Criteria:\n\n* • Patients with acute coronary syndrome.\n\n * Patients with chronic upper limb ischemia\n * Patients with AV fistula\n * Patients with severe renal impairment\n * Failure to successfully cannulate the radial artery'}, 'identificationModule': {'nctId': 'NCT05626660', 'briefTitle': 'Comparison Between Right and Left Radial Approach in Patients Undergoing Percutaneous Coronary Procedures', 'organization': {'class': 'OTHER', 'fullName': 'Assiut University'}, 'officialTitle': 'Comparison Between Right and Left Radial Approach in Patients Undergoing Percutaneous Coronary Procedures', 'orgStudyIdInfo': {'id': 'Coronary procedures'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Right Radial Group', 'interventionNames': ['Other: Coronary angiography and percutaneous coronary intervention']}, {'label': 'Left Radial Group', 'interventionNames': ['Other: Coronary angiography and percutaneous coronary intervention']}], 'interventions': [{'name': 'Coronary angiography and percutaneous coronary intervention', 'type': 'OTHER', 'description': 'Coronary angiography and percutaneous coronary intervention via radial approach', 'armGroupLabels': ['Left Radial Group', 'Right Radial Group']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Asyut', 'state': 'Asyut Governorate', 'country': 'Egypt', 'facility': 'Assiut University', 'geoPoint': {'lat': 27.18096, 'lon': 31.18368}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Assiut University', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Doctor', 'investigatorFullName': 'Kerillos Alfy Ayoub Salib', 'investigatorAffiliation': 'Assiut University'}}}}
