NCT02758964

Brief Summary

EARTH-TAVR is a diagnostic multicenter study to evaluate the occurrence and extent of cerebral embolization (total new lesion volume) in patients before TAVR versus 3 months after TAVR.

Outcome Measures

Primary Outcomes (1)

  • Total volume of new cerebral lesions on MRI, 3 months after TAVR versus Baseline

    Occurrence and extent of cerebral embolization in patients after TAVR measured by total volume of new ischemic cerebral lesions on DWI and FLAIR MRI. Total new lesion volume is defined as the sum volume of all new cerebral ischemic lesions on the 3 months post-procedural MRI relative to the pre-TAVR cerebral MRI scan (on diffusion weighted and FLAIR MRI images)

    3 months after TAVR versus baseline

Secondary Outcomes (5)

  • New lesion volume of cerebral embolization in patients treated with ASS and rivaroxaban 10mg OD versus an antiplatelet -based strategy with ASS and clopidogrel.

    3 months post TAVR versus baseline

  • extent and location of new cerebral lesions early AFTER TAVR and after 3 months

    MRI after TAVR (0-7 days after TAVR) compared to 3 months after TAVR

  • Assessment of different neurocognitive tests (NIHSS-score, MOCA-score, MOT-score, PAL-score, RTI-score, SWM-score, AST-score, CAM-Score); change of sum scores before, after and 3 months after TAVR procedure.

    Before TAVR, post TAVR and after 3 months

  • Extent and localization of clinically apparent non-cerebral emboli after TAVR

    baseline, post TAVR and after 3 months

  • Evaluation of possible changes in quality of life after TAVI with EQ-5D questionnaire sum score.

    Baseline versus 3 months following TAVR

Interventions

A cerebral MRI and neurocognitive testing will be performed before TAVR, before hospital discharge and after 3 months

Study Population

Patients 18 years or older wirth aortic valve stenosis receiving TAVR-Intervention.

You may qualify if:

  • Man or woman of 18 years of age or older
  • Via iliofemoral or subclavian access
  • Provide written IC

You may not qualify if:

  • Atrial fibrillation (AF), current or previous, with an ongoing indication for oral anticoagulant Treatment
  • Any other indication for continued treatment with any oral anticoagulant (OAC)
  • Known bleeding diathesis (such as but not limited to active internal bleeding, clinically significant bleeding, platelet count ≤ 50,000/mm3 at screening, hemoglobin level \< 8.5 g/dL, active peptic ulcer or known gastrointestinal (GI) bleeding, history of intracranial hemorrhage or subdural hematoma)
  • Any indication for dual-antiplatelet therapy (DAPT) for more than 3 months after randomization (such as coronary, carotid or peripheral stent implantation)
  • Clinically overt stroke within the last 3 months
  • Planned coronary or vascular intervention or major surgery
  • Severe renal impairment (eGFR \< 30 mL/min/1.73 m2) or on dialysis, or post-TAVR unresolved acute kidney injury with renal dysfunction stage 2 or higher
  • Moderate and severe hepatic impairment (Child-Pugh Class B or C) or any hepatic disease associated with coagulopathy
  • Any contraindication for cerebral MRI, in particular:
  • non-MRI-conditional pacemakers
  • MRI conditional pacemakers \<4 weeks after implant
  • any metal fragments in the eye
  • aneurysm clip in the brain
  • severe claustrophobia
