Clinical experience with the Heartflotrade mark System in coronary surgery

Area of Science:

• Cardiovascular Surgery
• Medical Device Technology
• Surgical Innovation

Background:

• Coronary artery bypass grafting (CABG) traditionally uses time-consuming suturing techniques for distal anastomoses.
• Automated suturing devices aim to improve efficiency and consistency in CABG procedures.

Purpose of the Study:

• To evaluate the safety and efficacy of the Heartflow anastomotic device for creating distal coronary anastomoses.
• To assess the feasibility of using the device on small coronary arteries (1.5 mm).

Main Methods:

• The Heartflow device delivers ten simultaneous sutures to form the anastomosis.
• Extensive animal studies preceded clinical testing across European and Canadian centers.
• Device modifications included changes to foot shape and diameter for improved performance.

Main Results:

• Successful grafting of 1.5 mm coronary arteries was achieved with the modified device.
• No device-related injuries were reported during clinical studies and early follow-up.
• Suture management remained a time-consuming aspect of the procedure.

Conclusions:

• The Heartflow device demonstrates potential for automating CABG anastomoses.
• Further advancements in automated knot tying or simplified suture management are crucial for clinical adoption.
• The device shows promise for improving surgical efficiency in cardiac procedures.
