Transcatheter aortic valve replacement outcomes in patients with high gradient versus low ejection fraction low gradient severe aortic stenosis: A meta-analysis of randomized controlled trials
Abstract
Background
The outcome of Low Flow-Low Gradient (LF-LG) severe aortic stenosis (AS) patients who underwent Transcatheter Aortic Valve Replacement (TAVR) procedure is not well defined. We conducted a systematic review of the literature to compare the outcomes of TAVR in LF-LG AS patients to the more traditional high gradient (HG) aortic stenosis.
