Association between frailty and postoperative delirium after transcatheter aortic valve replacement: a meta-analysis
Kai Ren
BackgroundPostoperative delirium (POD) is a common complication following transcatheter aortic valve replacement (TAVR) and is associated with adverse outcomes in older patients.

This meta-analysis aimed to evaluate the association between frailty and POD after TAVR.MethodsA systematic search of PubMed, Embase, and Web of Science wa
