简要总结

To investigate whether the collagen-based MANTA vascular closure device (VCD) is superior to suture-based VCDs in preventing vascular access site complications in patients undergoing transfemoral transcatheter aortic valve replacement.

接受健康志愿者

入选标准

  • Patients undergoing elective transfemoral TAVI for severe aortic valve stenosis with any commercially-available transcatheter heart valve (THV)
  • Common femoral artery diameter > 5.0mm (14 - 22F compatible)

排除标准

  • Symptomatic leg ischaemia
  • Previous thromboendarterectomy or plastic patch of the common femoral artery
  • Previous implantation of a suture-based VCD less than 30 days before, or a plug-based VCD within 6 months
  • Unilateral or bilateral lower extremity amputation
  • Systemic infection or a local infection at or near the access site
  • Allergy to the components any of both devices (i.e. bovine materials or any other device material, including collagen and/or collagen products, polyglycolic or polylactic acid, stainless steel or nickel)
  • Active bleeding or bleeding diathesis including thrombocytopenia (platelet count <50,000 cells/UL), thrombasthenia, hemophilia, or von Willebrand disease
  • Patients in whom continuous oral anticoagulation therapy cannot be stopped for the peri-procedural period or patients with INR >1.8 at the time of the procedure
  • Patient unable to be adequately anti-coagulated for the procedure
  • Morbidly obese or cachectic (BMI >40 kg/m2 or <20 kg/m2)
  • Anatomical and procedural contraindication for suture-based or Manta closure (lack of proper puncture site in the common femoral artery in terms of calcification, size, and atherosclerotic disease)
  • Absence of computed tomographic data of the access site before the procedure
  • Patient cannot adhere to or complete the investigational protocol for any reason including but not limited to geographical residence, psychiatric condition or life threatening disease
  • Known pregnancy at time of randomization (in women of childbearing potential a negative pregnancy test is mandatory)
  • Participating in trials in which the primary endpoint includes bleeding or vascular complications

结局指标

主要结局

Composite rate of major- and minor vascular complications according to VARC-2

时间窗: Between transcatheter aortic valve implantation and 30 days follow-up

The primary endpoint will consist of the composite of major- and minor vascular complications according to the Valve Academic Research Consortium (VARC)-2 at 30 days follow-up.

次要结局

  • Number of Participants with a Major Vascular Complication according to VARC-2(Between transcatheter aortic valve implantation and 30 days follow-up)
  • Number of Participants with a Minor Vascular Complication according to VARC-2(Between transcatheter aortic valve implantation and 30 days follow-up)
  • Time to hemostasis(During the TAVI procedure)
  • Length of hospital stay(Up to a maximum of 30 days after the TAVI procedure)
  • All-cause death rate(Between transcatheter aortic valve implantation and 30 days follow-up)
  • Number of Participants with a major- or life threatening bleeding according to VARC-2(Between transcatheter aortic valve implantation and 30 days follow-up)
  • Need for transfusions for access site related bleeding/complications(Between transcatheter aortic valve implantation and 30 days follow-up)
  • Number of Participants with vascular closure device failure(Between transcatheter aortic valve implantation and 30 days follow-up)
  • Total procedure time(During the TAVI procedure)
  • Number of Participants with a clinically relevant bleeding defined as BARC 2, 3 and 5(Between transcatheter aortic valve implantation and 30 days follow-up)
