Insights
Minimally invasive coronary artery bypass grafting using the Octopus system on a beating heart showed no mortality and shorter hospital stays. Short-term results were comparable to traditional cardiopulmonary bypass methods.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Procedures
- Medical Devices
Background:
- Minimally invasive coronary artery bypass grafting (CABG) techniques are debated.
- This study evaluates the Medtronic Octopus Tissue Stabilization System for beating heart CABG.
Purpose of the Study:
- To compare outcomes of beating heart CABG using the Octopus system with standard cardiopulmonary bypass (CPB).
Main Methods:
- Eighty-nine patients underwent single or multiple vessel bypass using the Octopus system.
- Outcomes including complications, length of stay, and functional status were assessed.
- Follow-up averaged 162.3 days, with selective postoperative stress testing and angiograms.
Main Results:
- Eighty-three of 89 patients completed surgery without CPB using the Octopus system, with no mortality.
- Morbidities were similar to a CPB group (369 patients).
- The Octopus group experienced a significantly shorter postoperative length of stay (p = 0.005).
Conclusions:
- The Octopus system offers predictable and reproducible myocardial immobilization.
- Short-term outcomes of beating heart CABG with the Octopus system are comparable to standard CPB.
Background:
The practice of minimally invasive coronary artery bypass grafting remains controversial. This study outlines the results of single and multiple vessel bypass performed using the Medtronic Octopus Tissue Stabilization System and beating heart techniques. Results are compared with those of a standard cardiopulmonary bypass group.
Methods:
The group included 89 patients having operations performed during a 10-month period with average follow-up of 162.3 days. Complications, length of stay, and functional status were recorded. Postoperative stress testing and angiograms were performed selectively.
Results:
The average age was 62.3 years and the average ejection fraction was 0.65. Twenty-five percent of the patients underwent operations urgently or emergently, averaging 1.8 grafts/patient. In 83 of 89 patients operations were completed without cardiopulmonary bypass using the Octopus without mortality. Morbidities were statistically similar to a group of 369 cardiopulmonary bypass patients. Postoperative length of stay was shorter in the Octopus group (p = 0.005).
Conclusions:
The Octopus provided predictable, reproducible immobilization with short-term results comparable with those obtained with standard cardiopulmonary bypass.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
