Short- and long-term outcomes in patients undergoing valve surgery with end-stage renal failure receiving chronic hemodialysis

Objectives The objective of this study was to evaluate the effect of chronic preoperative hemodialysis for end-stage renal failure in patients undergoing valve surgery. Methods A retrospective review of patients undergoing primary valve with or without coronary artery bypass surgery from 1996 to 2008 at a US academic center was performed. The patients were divided into two groups: group 1 underwent valve surgery without preoperative dialysis (n = 5084) and group 2 underwent valve surgery with preoperative dialysis (n = 224). The outcomes were evaluated using multivariate regression analysis, and long-term survival was assessed with Kaplan-Meier plots. Results The patients in group 2 were younger ( P
