Why the study?
Does patient-prosthesis mismatch combined with advanced NYHA class predict short-term mortality in patients undergoing AVR with or without CABG?
Population
509 patients undergoing aortic valve replacement (AVR) or AVR+CABG from 2006 to 2010
Design
Cohort
Follow-up
30-day to in-hospital

Low short-term AVR mortality supports proceeding in octogenarians; observational data leaves open whether avoiding PPM reduces risk in NYHA III-IV.
Does patient-prosthesis mismatch combined with advanced NYHA class predict short-term mortality in patients undergoing AVR with or without CABG?
Short-term mortality after AVR with or without CABG is low even in octogenarians, though patient-prosthesis mismatch in the setting of advanced heart failure increases risk.
