In our cohort of octogenarians, cardiac surgery was found to be associated with an acceptable, although increased perioperative mortality. Despite the enhanced perioperative risk, the clinical benefit, as verified by improved functional status and satisfactory mid-term survival rates, justifies surgery in these patients with advanced age.

Severe obesity does not PER SE enhance perioperative mortality. A BMI of 30 to 50 combined with diabetes mellitus and bilateral ITA grafting increases the risk for sternal complications.
