Minimally invasive direct coronary artery bypass in a child with an occlusion of left main coronary artery after arterial switch operation

Clinical Effect and Prognosis of Off-Pump Minimally Invasive Direct Coronary Artery Bypass

Background

Coronary artery bypass grafting (CABG) is a common procedure to circumvent the obstruction of coronary arteries when stents are unsuitable. CABG is a very traumatic surgery that requires redirecting blood flow to an external pump. Thus, this procedure has many risks during and after surgery, and minimizing these risks would greatly benefit the patients.

Material/Methods

We selected 126 patients with coronary artery syndrome and who were unsuitable for stent percutaneous coronary intervention. The observation group received minimally invasive direct coronary artery bypass (MIDCAB), while the control group was treated with off-pump CABG.

Results

Blood markers and echocardiography before and after treatment improved equally in both groups. Neither group exhibited obvious adverse reactions, or liver and kidney function damage. However, surgical bleeding and postoperative observation days were significantly reduced in the MIDCAB group. Death and cardiac shock at the end of follow-up were significantly lower in the MIDCAB group.

Conclusions

Overall, the clinical benefits of MIDCAB and OP-CABG were similar, but MIDCAB significantly reduced postoperative hospital stay and intraoperative blood transfusion, and improved clinical prognosis.
