Is transcatheter aortic valve implantation feasible in patients with chronic kidney disease?

The authors compared transcatheter aortic valve implantation (TAVI) to conservative medical therapy in stage 3-5 chronic kidney disease (CKD) patients. They demonstrated that TAVI is associated with improved survival at one year compared to conservative therapy. This study is of vital importance as many of the physicians are hesitant to refer advanced stage CKD patients for TAVI as the data have been conflicting in previous studies. We agree that ...
