Objectives

Narrative objectives1

This clinical study involves patients undergoing transcatheter aortic valve replacement as a treatment for aortic stenosis. The purpose of the study is to evaluate whether the anti-thrombotic therapy (blood thinning medication) taken by patients undergoing transcatheter aortic valve replacement is effective in inhibiting the process of blood clot formation before and after treatment. By accumulating this data, we will identify safer and more effective antithrombotic therapy for transcatheter aortic valve replacement in Japanese patients.
