The New York State Department of Health released its report on adult cardiac surgery in New York State for 2013-2015. The report provides information on mortality rates after coronary artery bypass graft (CABG) surgery and valve repair or replacement surgery, readmissions after CABG, and preliminary information on transcatheter aortic valve replacement (TAVR) in NYS. The report also describes patient risk factors associated with mortality for CABG and valve surgery and those associated with readmissions after CABG surgery. This report is based on data for patients discharged between December 1, 2012, and November 30, 2015, provided by all non-federal hospitals in NYS where cardiac surgery is performed. The analysis period for this report includes patients discharged in December 2012 but not those discharged in December 2015.
