Abstract
Background and purpose: Minimally invasive coronary artery bypass grafting (CABG) has been facilitated by the introduction of the Octopus Tissue Stabi lization system (OTS). OTS improves exposure immobilizing the heart with mi nimal hemodynamic effects allowing multivessels off cardiopulmonary bypass (CPB) CABG. The purpose of this study was to compare the utilization and cl inical outcome of the OTS in three geographically distinct centers. Methods : 239 patients who underwent OTS-CABG at Allegheny University Hospital/Medi cal College of Pennsylvania, Harrisburg Hospital, and Park Nicollet Clinic/ HealthSystem Minnesota were reviewed. Age, acuity of patients, and number a nd type of vessels bypassed were recorded. Complications, mortality, length of hospital stay, incidence of conversion to CPB and blood transfusions, a nd operating room costs were compared to risk matched control patients who underwent CPB CABG during the same period. Results: Results were similar in all three centers. The average age was 62.3 years. Emergent operation was necessary in 7%-10% of patients, the operations averaged 1.8 grafts/patient . Arteries bypassed were LAD, DIAG, OM, RCA, PDA, and RPLB. There were 96% of operations completed without CPB. Morbidity was low (12%). Atrial fibril lation and blood transfusion rate were decreased. Mortality was 0 compared with a predicted mortality of 1.6%. Hospital length of stay was shorter and operating room costs were 61% lower. Conclusions.. OTS provides predictabl e reproducible immobilization allowing the performance of single and multip le off-pump CABG to almost all coronary branches with minimal morbidity and decreased costs in a variety of patients. Similar findings from three diff erent centers suggests that these results are easily reproducible.
