Target recruitment is 260 adults with aortic root aneurysms and/or dystrophic aortic insufficiency, enrolled in 19 french centers. Patients will undergo a standardized aortic valve sparing procedure based on aortic annuloplasty or a mechanical valve replacement (130 patients in each arm). In case of valve sparing, per-operative transoesophageal echocardiography will evaluate residual aortic insufficiency after valve repair. A conversion towards a valve replacement will be performed if residual aortic insufficiency is superior or equal to grade II.\n\nAnalysis will be on an intention-to-treat basis, completed with a per-protocol analysis. Primary endpoint will be 3-years survival free of morbidity or mortality, evaluated on a composite criterion, associating mortality; structural and non-structural valvular dysfunction, valve thrombosis, embolism, bleeding event, endocarditis, reoperations and permanent valve-related impairment. In the valve sparing group, we expect less than 5% rate of operative conversion and a significant improvement of primary endpoint. As secondary goals, quality of life and criteria of valvular coaptation will be compared between the 2 groups.\n\nStandardization is the prerequisite for evaluation of valve sparing procedure. Aim of CAVIAAR trial is to provide evidence based medicine data for the best surgical management of patients with aortic root aneurysms and/or dystrophic aortic insufficiency.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'INCLUSION CRITERIA :\n\n* Adult patients with indications for elective surgery of aortic root aneurysms (bicuspid or tricuspid valves) conformed to AHA or ESC guidelines or Adult patients with indications for elective surgery of isolated dystrophic aortic insufficiency (bicuspid or tricuspid valves) conformed to AHA or ESC guidelines\n* signed informed consent\n\nEXCLUSION CRITERIA :\n\n* Aortic stenosis\n* Acute ascending aorta dissections\n* Contra-indications to oral anticoagulation in case of Arm 2 (mechanical valve)\n* Life expectancy \\< 36 mois Contra-indication for implantation of the expansible rings in Arm 1: patients are known to have sensitivity to polyester or silicone, the aortic wall is deemed unusually thin and/or friable above the native aortic annular base or local anatomy impairs the safe implantation of the device in the subvalvular position (hypertrophic cardiomyopathy with septal obstruction of the left ventricular outflow tract, calcifications, adhesions…)'}, 'identificationModule': {'nctId': 'NCT00478803', 'acronym': 'CAVIAAR', 'briefTitle': 'Conservative Aortic Valve Surgery for Aortic Insufficiency and Aneurysms of the Aortic Root.
