Minimally invasive direct coronary artery bypass (MIDCAB) was associated with better 7-year LVEF and vessel patency rates compared to median sternotomy off-pump CABG (p<0.05).

Does MIDCAB improve perioperative outcomes and mid-term vessel patency compared to median sternotomy OPCAB in patients undergoing off-pump coronary artery bypass?
MIDCAB offers a safe and effective alternative to traditional median sternotomy OPCAB, with improved perioperative recovery and favorable 7-year vessel patency.
p-value: p=<0.05
To investigate the clinical significance of minimally invasive direct coronary artery bypass (MIDCAB). Three hundred patients admitted to the Second Hospital of Shandong University from March 2006 to February 2010 were retrospectively analyzed and received off-pump operation under general anesthesia. Depending on surgical methods, patients were divided into the MIDCAB group (n = 90) and the median sternotomy off-pump coronary artery bypass (OPCAB) group, named as the OPCAB group (n = 210). Preoperative clinical data, perioperative clinical data, and mid-term follow-up at 7 years after operation were analyzed and compared between the two groups. Age and the number of vascular lesions in the OPCAB group were higher than those in the MIDCAB group, whereas left ventricular ejection fraction (LVEF) in the former was lower than that in the latter (p<0.05). The number of distal anastomotic stomas, operation time, blood transfusion volume, postoperative cardiac troponin I (cTnI) peak value, ventilator use time, intensive care unit (ICU) stay, and hospital stay in the MIDCAB group were significantly lower than those in the traditional OPCAB group (p<0.05). Among the 294 recovered cases, 201 cases completed 7 years of continuous follow-up, with a follow-up rate of 67.91%. The LVEF and the patency rate of vessels in the MIDCAB group were higher than those in the OPCAB group (p<0.05). Compared with the median sternotomy OPCAB, MIDCAB is characterized by small incision, small trauma, positive efficacy, and safety; therefore, it is worthy of being promoted.
Xu et al. (Sun,) conducted a cohort in Coronary artery disease requiring bypass surgery (n=300). Minimally invasive direct coronary artery bypass (MIDCAB) vs. Median sternotomy off-pump coronary artery bypass (OPCAB) was evaluated on Perioperative outcomes, 7-year LVEF, and vessel patency rate (p=<0.05). Minimally invasive direct coronary artery bypass (MIDCAB) was associated with better 7-year LVEF and vessel patency rates compared to median sternotomy off-pump CABG (p<0.05).
