Evolving trends of reoperative coronary artery bypass grafting: An analysis of the Society of Thoracic Surgeons Adult Cardiac Surgery Database

ObjectiveThe present study evaluated the evolving trends and outcomes of patients undergoing isolated reoperative coronary artery bypass grafting at Society of Thoracic Surgeons Adult Cardiac Surgery Database–participating institutions.MethodsFrom 2000 to 2009, 72,431 patients underwent isolated reoperative coronary artery bypass grafting and 1,497,254 patients underwent isolated primary coronary artery bypass grafting at Society of Thoracic Surgeons–participating institutions. The demographics, operative characteristics, and risk-adjusted postoperative outcomes were assessed and compared during the study period.ResultsAs a percentage of overall coronary artery bypass grafting volume, reoperative coronary artery bypass grafting decreased from 6.0% (8820/137,267) in 2000 to 3.4% (5734/160,997) in 2009. The unadjusted operative mortality declined from 6.1% (542/8820) in 2000 to 4.6% (261/5734) in 2009 (P
