Outcomes

Primary Outcome Measures

Safety and efficacy of Ticagrelor vs Aspirin in the incidence of NACE at 12 months after TAVI.
NACE is a composite of: all-cause mortality, transient ischemic attack (TIA) or stroke, myocardial infarction, progressive angina leading to emergency evaluation,rehospitalization or new coronary angiography, valve thrombosis, claudication, acute limb ischemia leading to hospitalization, any bleeding.

Secondary Outcome Measures

Efficacy endpoint: Subclinical valve thrombosis
Detected by hypoattenuated leaflet thickening (HALT) and reduced leaflet motion(RLM) at 3 and 12 months after TAVI assessed by 4-dimensional computed tomography (4D-CT) imaging. HALT: Hypoattenuating thickening in typically meniscal configuration on one or more leaflets, with or without RLM. The extent of HALT should be described per leaflet, using a 4-tier grading scale in regard to leaflet involvement along the curvilinear contour, assuming maximum involvement at the base of the leaflet: ≤25% (limited to the base) >25% and ≤50% >50% and ≤75% >75% Inconclusive for HALT: imaging with insufficient image quality or presence of artifact RLM: The extent of RLM should be described per leaflet, using a 4-tier grading scale None: no reduction in leaflet excursion <50% reduction in leaflet excursion ≥50% reduction in leaflet excursion Immobile: immobile leaflet Inconclusive for RLM: imaging with insufficient image quality or presence of artefact
Safety endpoint: Major bleeding
Major bleeding (type 2, 3 and 5) at 12 months after TAVI according BARC (Bleeding Academic Research Consortium)
Patient-oriented composite endpoints
Patient-oriented composite endpoints (POCE) at 12 months after TAVI (POCE is a composite of all-cause mortality,TIA/stroke, myocardial infarction, progressive angina leading to emergency evaluation, rehospitalization or new coronary angiography).

5. Study Description

Brief Summary
The optimal pharmacological therapy after transcatheter aortic valve implantation (TAVI) to prevent valve thrombosis and reduce thromboembolic complications without significantly increasing the risk of bleeding is not yet fully defined and constitutes an important unmet clinical need. Recently, single antiplatelet therapy (SAPT) with Aspirin has been increasingly adopted to avoid bleeding early after TAVI compared with dual antiplatelet therapy. However, TAVI population is affected by a diversity of chronic pathologies that increase the risk of post-TAVI ischemic complications. Stroke is prevalent, especially peri- and early post-TAVI (<1-8% in the 1st year). Although peri-TAVI myocardial infarction (MI) is rare (1-3%), concomitant coronary artery disease (CAD), diabetes mellitus (DM), and peripheral vascular disease (PVD), is very frequent in the TAVI population, affecting around 30-70% of patients. In patients with CAD, the need to re-access the coronary arteries after TAVI is challenging and can be hampered by the trancatheter valve struts. This is critical in TAVI patients with an acute coronary syndrome and in younger patients with long-life expectancy after TAVI. The use of a P2Y12 inhibitor provides significant ischemic protection in the in the coronary, cerebral and peripheral vascular territories compare to Aspirin. The use of a P2Y12 inhibitor as antiplatelet treatment can decrease the need for new coronary revascularizations and reduce the incidence of thromboembolic complications after TAVI.
