This study aims to provide prospective data from a large cohort of TEVAR patients to explore clinical outcomes following TEVAR procedures and, specifically, whether right atrial occlusion has significant impact on clinical outcomes, as compared to other REAI techniques. The results from this study may inform future perioperative TEVAR practices and improve TEVAR patient outcomes.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'All patients undergoing emergency or elective thoracic endovascular aortic repair at the Peter Lougheed Centre, Calgary, Alberta', 'eligibilityCriteria': 'Inclusion Criteria:\n\n* age 18 years or older\n* thoracic endovascular aortic repair\n* right atrial balloon occlusion for reduction or elimination of aortic impulse\n* endograft deployment in landing zones 0-3\n\nExclusion Criteria:\n\n* age 18 years or younger\n* non-thoracic endovascular aortic repair\n* reduction or elimination of aortic impulse using technique other than right atrial balloon occlusion\n* endograft deployment in landing zones 4 and beyond'}, 'identificationModule': {'nctId': 'NCT06786351', 'briefTitle': 'Impact of Right Atrial Occlusion on TEVAR Outcomes', 'organization': {'class': 'OTHER', 'fullName': 'University of Calgary'}, 'officialTitle': 'Impact of Right Atrial Occlusion on TEVAR Outcomes: A Prospective Cohort Study', 'orgStudyIdInfo': {'id': 'REB24-1367'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Right atrial balloon occlusion', 'description': 'Thoracic endovascular aortic repair with right atrial balloon occlusion for reduction or elimination of aortic impulse', 'interventionNames': ['Procedure: Right atrial balloon occlusion']}, {'label': 'Non right atrial balloon occlusion', 'description': 'Thoracic endovascular aortic repair not using right atrial balloon occlusion for reduction or elimination of aortic impulse', 'interventionNames': ['Procedure: Non right atrial balloon occlusion']}], 'interventions': [{'name': 'Right atrial balloon occlusion', 'type': 'PROCEDURE', 'description': 'Thoracic endovascular aortic repair with right atrial balloon occlusion for reduction or elimination of aortic impulse and stent graft deployment in landing zones 0-3', 'armGroupLabels': ['Right atrial balloon occlusion']}, {'name': 'Non right atrial balloon occlusion', 'type': 'PROCEDURE', 'description': 'Thoracic endovascular aortic repair not using right atrial balloon occlusion for reduction or elimination of aortic impulse and stent graft deployment in landing zones 0-3', 'armGroupLabels': ['Non right atrial balloon occlusion']}]}, 'contactsLocationsModule': {'centralContacts': [{'name': 'Claire Allen, MD, FRCPC', 'role': 'CONTACT', 'email': 'claire.allen@ahs.ca', 'phone': '403-'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Calgary', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Clinical Lecturer', 'investigatorFullName': 'Claire Allen', 'investigatorAffiliation': 'University of Calgary'}}}}
