Aspirin Versus Aspirin+Clopidogrel as Antithrombotic Treatment Following TAVI

Summary

The purpose of this study is to compare aspirin/acetylsalicylic acid+ clopidogrel with aspirin/acetylsalicylic acid alone as antithrombotic treatment following TAVI for the prevention of major ischemic events (MI, ischemic stroke) or death without increasing the risk of major bleeding events.
