Clinical Trial Summary

The purpose of this study is to evaluate the safety and effectiveness of transcatheter aortic valve replacement in Chinese population.

Description:

Subjects enrolled are those who undergo physical exams and screening tests and were classified as a patient with symptomatic aortic stenosis or severe aortic regurgitation. They are then performed transcatheter aortic valve replacement.
