Insights
The Kyocera Gyro C1E3 centrifugal blood pump demonstrated excellent controllability and safety during cardiopulmonary bypass (CPB) for coronary artery bypass grafting (CABG). No significant hemolysis or thrombi were observed, marking a successful clinical application.
Area of Science:
- Cardiovascular Surgery
- Biomedical Engineering
- Medical Device Technology
Background:
- Coronary artery bypass grafting (CABG) often requires cardiopulmonary bypass (CPB).
- Centrifugal blood pumps are critical components in CPB circuits.
- Evaluating novel pump technologies for safety and efficacy is essential.
Observation:
- The Kyocera Gyro C1E3 centrifugal blood pump was used in a 72-year-old male undergoing CABG.
- The pump exhibited easy and rapid air removal, with excellent controllability during the procedure.
- Pump flow was maintained at 2.2 L/m2 over a total CPB time of 173 minutes.
Findings:
- Perioperative hemolysis and cytotoxicity levels remained unchanged.
- Post-usage examination revealed no macroscopic or microscopic thrombi within the pump.
- The Kyocera Gyro C1E3 pump proved to be a safe and effective device in this clinical setting.
Implications:
- This case report represents the first clinical application of the Kyocera Gyro C1E3 centrifugal blood pump.
- The findings support the potential of this device for use in cardiopulmonary bypass procedures.
- Further studies are warranted to confirm the long-term performance and broader clinical utility of the Kyocera Gyro C1E3 pump.
Abstract:
The Kyocera Gyro C1E3 centrifugal blood pump was clinically applied for a cardiopulmonary bypass (CPB) of coronary artery bypass grafting (CABG). The patient was 72-year-old male with postinfarction unstable angina. The surgery was carried out on November 20, 1998. The air inside the pump was easily and quickly removed, and its controllability was excellent. The pump flow during operation was maintained 2.2 L/m2. Total CPB time was 173 min. Perioperative parameters of hemolysis and cytotoxicity were not remarkably changed. Macroscopically and microscopically, there were no thrombi inside the pump after usage. This is the first reported case of clinical use of the Kyocera Gyro C1E3 pump.
