Diferencias entre la cirugía de derivación de arteria coronaria con la bomba en funcionamiento y con la bomba apagada en octogenarios. Background: The elderly population has been continuously growing throughout most of the world. With increase in the older population, the number of patients (pts) referred for coronary artery bypass grafting (CABG) has also increased, most of them undergo On-pump coronary artery bypass (ONCAB) surgery, even thought, the risk for morbidity and mortality in this group of the pts are higher when compared to younger age group. Off-pump coronary artery bypass (OPCAB) surgery is being considered as an alternative. Objective: Determine the potential benefits of OPCAB surgery in octogenarians. Methods: Records of 69 consecutive elderly pts with coronary artery disease who underwent CABG, were retrospectively reviewed, 53 pts submitted to a ONCAB surgery, Group I (GI), (47.17% female, Age > 80 y/o) and 15 pts to a OPCAB surgery, Group II (GII), (66.67% female, age > 80 y/o). The following parameters were collected, preoperative risk factors, operative and postoperative complication and mortality. Results: In the GII operative time was lower (p = 0.032), requiring less unit of packed red blood cells (p = 0.0042), and fresh frozen plasma (p = 0.0142) than the GI, postoperative complication (p = 0.031), mean hospital stay (p = 0.0032) and mortality (p = 0.007) were also significantly lower in the GII. There was a trend toward a higher intensive care unit stay (p = 0.0840) and a higher incidence of atrial fibrillation (p = 0.024) in the GI. Conclusion: In both groups of the octogenarians, CABG was performed with acceptable risk. However in the GII a reduction on the inhospital stay, morbidity and mortality was observed.
