Objective:
To analyze the in-hospital outcome of elderly patients aged 70 years and older who underwent off-pump coronary artery bypass graft surgery with an intraluminal shunt in urgent, emergent, and elective coronary revascularizations.
Methods:
From July 1989 to July 2005, we analyzed 87 patients ranging in age from 70 to 92 years. Of the 87 patients enrolled, 50 (57.5%) patients had unstable angina, with three (3.4%) acute myocardial infarction; thirty-one (35.6%) patients underwent urgent and emergent surgery; thirteen (14.9%) patients had myocardial infarction in less than 30 days, and 34 (39.1%) in more than 30 days.
Results:
The main postoperative complications were: atrial fibrillation (32.2%), heart failure (12.6%), pneumonia (10.3%), septicemia (3.4%), acute myocardial infarction (2.3%), mediastinitis (1.1%) transient ischemic attack (1.1%), and pneumothorax (1.1%). The mean extubation time was 18.50+/-19.09 hours, the length of stay in the intensive care unit was 2.92+/-2.03 days, and hospital length of stay was 10.55+/-7.16 days. Packed red cells were given to nine (10.34%) patients and none of them was operated due to bleeding. The in-hospital mortality was 4.6%.
Conclusions:
In patients over 70 years-old, elective and non-elective off-pump coronary artery bypass grafting with intracoronary shunt showed to be safe and effective, associated with low rates of postoperative complications and mortality in relation to the studied population.
