The invasive measurements will be performed in different positions of the ventricle and aorta simultaneously. At the end of the procedure, aortic gradient measurement by echocardiography shall be performed again. A maximal three months follow-up is expected.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'All consecutive patients with severe aortic valve stenosis undergoing TAVI with balloon-expandable transcatheter heart valves (THV).', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age ≥ 18 years and able to give consent\n* Severe symptomatic native aortic valve stenosis with indication for TAVI according to 2021 ESC/EACTS Valvular Heart Disease Guidelines.\n* Use of balloon-expandable THV\n* Written informed consent\n\nExclusion Criteria:\n\n* Emergency or urgent treatment indication\n* Patients under hemodynamically unstable conditions.\n* Previous bioprosthetic aortic valve implantation\n* Patient cannot adhere to or complete the trial protocol for any reason'}, 'identificationModule': {'nctId': 'NCT06753227', 'acronym': 'IVEGA-TAVI', 'briefTitle': 'Invasive Versus Echocardiography-derived Transvalvular Gradients After TAVI Usign Balloon-expandable Transcatheter Heart Valves.', 'organization': {'class': 'OTHER', 'fullName': 'Deutsches Herzzentrum Muenchen'}, 'officialTitle': 'Systematic Assessment of Invasive Versus Echocardiography-derived Transprosthetic Gradients After Transcatheter Aortic Valve Implantation Using Balloon-expandable Transcatheter Heart Valves: the IVEGA-TAVI Study.', 'orgStudyIdInfo': {'id': '2023-456-S-SB'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Patients with severe aortic valve stenosis requiring transcatheter aortic valve implantation'}]}, 'contactsLocationsModule': {'locations': [{'zip': '80636', 'city': 'Munich', 'state': 'Bavaria', 'country': 'Germany', 'facility': 'Deutsches Herzzentrum München', 'geoPoint': {'lat': 48.13743, 'lon': 11.57549}}], 'overallOfficials': [{'name': 'Michael Joner, Professor Dr. med.', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Deutsches Herzzentrum München'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Deutsches Herzzentrum Muenchen', 'class': 'OTHER'}, 'collaborators': [{'name': 'Edwards Lifesciences', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
