The study of Single or Dual antiplatelet therapy after transcatheter aortic valve implantation
The company Fundacin Biomedica Galicia Sur is enrolling patients into the clinical trial investigating Single or Dual Antiplatelet Therapy After Transcatheter Aortic Valve Implantation (REAC-TAVI2).
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.
