[MSB-35] Initial Single-Center Experience: Outcomes of Minimally Invasive Extracorporeal Circulation vs. Conventional...

Area of Science:

• Cardiovascular Surgery
• Medical Devices

Background:

• Conventional cardiopulmonary bypass (cCPB) is standard for cardiac surgery.
• Minimally invasive extracorporeal circulation (MiECC) offers a potential alternative with reduced circuit volume.
• Early clinical experience with MiECC is valuable for understanding its impact.

Purpose of the Study:

• To present early clinical experience with MiECC circuits.
• To compare MiECC with cCPB in cardiac surgery patients.
• To evaluate outcomes including blood transfusion, drainage, and postoperative recovery.

Main Methods:

• Retrospective analysis of 239 patient registries (June 2021 - February 2024).
• Comparison between MiECC (45 patients) and cCPB groups.
• Restrictive blood transfusion protocol applied to all patients.

Main Results:

• MiECC significantly reduced red blood cell (RBC) suspensions transfusion and total drainage compared to cCPB.
• No significant differences in intubation duration, acute kidney injury, or hospital stay.
• Reduced RBC transfusion and drainage observed in geriatric patients and those with low ejection fraction (EF ≤45).

Conclusions:

• MiECC utilization led to decreased RBC transfusion and postoperative drainage.
• No significant differences in key clinical outcomes like intubation time or hospital stay were found.
• Further blinded studies are recommended to fully elucidate MiECC benefits, especially in specialized populations.
