Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement in Low-risk Patients: A Meta-Analysis Based on a 2-Year Follow-Up.

Background: Previous studies have shown that transcatheter aortic valve implantation is the best alternative therapy to surgical aortic valve replacement in high-risk surgical patients with aortic stenosis. However, it is not clear whether transcatheter aortic valve implantation can be utilized in low-risk surgical patients with aortic stenosis. This studyaimed to evaluate the safety and efficacy of transcatheter aortic valve implantation in low-risk patients.
