Abstract:


Background: The optimal antithrombotic therapies for transcatheter aortic valve implantation (TAVI) and MitraClip implantation have not been well established. We conducted a narrative review from currently available studies between January 2002 and May 2016 to highlight the advantages and disadvantages of antithrombotic therapy use in cardiac catheter-based therapeutic techniques. Recently, these techniques have dramatically altered the approach towards valvular heart diseases management. The introduction into clinical practice, of TAVI for severe aortic stenosis and MitraClip for mitral regurgitation, has revolutionized interventional cardiology. However, TAVI is associated with a risk of cerebral embolization and ischaemic vascular events leading to neurological impairment and even death. These ischaemic complications might occur perioperatively or much later, although the estimated rate of occurrence is variable.

Conclusion: We will discuss prior experience with MitraClip for antithrombotic use. It is imperative for patients undergoing transcatheter valvular interventions to have optimal antithrombotic therapy that balances between ischaemic and haemorrhagic complications. The appropriate timing, combination, and duration of antithrombotic medications need consensus to weigh between the efficacy, efficiency and adverse effects in patients with transcatheter valvular interventions.
