入选标准

  • Successful transfemoral TAVI for symptomatic aortic stenosis as defined by VARC-33 o Successful access, delivery of the device, and retrieval of the delivery system o Correct positioning of a single prosthetic heart valve into the proper anatomical location o Freedom from surgery or intervention related to the device (excluding permanent pacemaker) or to a major vascular or access-related, or cardiac structural complication
  • Written informed consent
  • Social security affiliated
  • French speaking
  • Male or, post-menopausal -with no menses for 12 months without an alternative medical cause- or permanently sterilized -hystercetomy, bilateral salpingectomy or bilateral oophorectomy- female

排除标准

  • Un-successful TAVI defined by the absence of any of the above-mentioned criteria defining successful TAVI
  • Women of childbearing potential: non menopaused -with no menses for 12 months without an alternative medical cause- and not permanently sterilized -hystercetomy, bilateral salpingectomy or bilateral oophorectomy-
  • Alternative non-femoral-approach TAVI: apical, direct trans-aortic, subclavian, axillary or carotid approaches
  • TAVI for other indications than aortic stenosis (pure aortic regurgitation)
  • Valve in valve TAVI
  • Any indication for long term antiplatelet therapy: (e.g. coronary artery disease, cerebrovascular disease, peripheral arterial disease…) at any time prior to randomization
  • Any indication for oral anticoagulation: (e.g. atrial fibrillation, deep vein thrombosis, pulmonary embolism, ventricular thrombus…) at any time prior to randomization
  • Patients on long term antiplatelet or anticoagulant therapy prior to TAVI for any other indication than TAVI
  • Any contraindication to long term antiplatelet therapy (e.g. allergy or intolerance to aspirin, major bleeding, high bleeding risk, thrombocytopenia < 50 000, major haemostasis disorder…)
  • Adult with protective measures (tutorship, curatorship)
