Transcatheter aortic valve replacement versus surgical aortic valve replacement in low‐surgical‐risk patients: An updated meta‐analysis

OBJECTIVE The purpose of this meta-analysis is to compare the safety and efficacy of transcatheter aortic-valve replacement (TAVR) to surgical aortic valve replacement (SAVR) in low-surgical-risk patients. BACKGROUND TAVR is proven to be safe and effective in patients with high- and intermediate-risk aortic stenosis. However, there is limited data on the safety and efficacy of TAVR in patients with low surgical risk. METHODS We conducted an electronic database search of all published data for studies that compared TAVR to SAVR in low-surgical-risk patients (mean society for thoracic surgery [STS] score
