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