Clinical Outcome of Cardiac Surgery in Octogenarians

ABSTRACT

The purpose of this study was to investigate the operative results and the clinical outcomes for octogenarians who underwent cardiac surgery. Twenty consecutive octogenarians who had cardiac operations at Samsung Medical Center from October 1994 through December 2004 were included in the study. The medical records were retrospectively reviewed and the follow-up results were obtained by the interview. The patients were 15 men and 5 women, and their mean age was 83.1 yr (range 80-89 yr). The surgical priority was urgent for 5 patients and it was elective for 15 patients. Coronary artery bypass grafting (CABG) was performed in 14 patients, valve surgery was performed in 4 patients and CABG plus valve surgery was performed in 2 patients. There was one hospital death on day one after urgent CABG in an 80-yr-old man who had left main coronary artery occlusion. There were three deaths during the follow-up. Sudden death occurred in one patient at 2 months after valve surgery, and there were two non-cardiac deaths at 12 and 14 months, respectively, after CABG. Non-fatal postoperative complications occurred in 2 of 5 urgent patients and in 3 of 15 electives. The survival rate for the 19 hospital survivors at 24 months after surgery was 80% and the mean follow-up period was 22.5 months (range 1-58 months). In conclusion, cardiac surgery could be performed within acceptable limits of the risk and its long-term results could be expected to be favorable for the octogenarians.
