MIDCAB versus off-pump CABG: Comparative study

Abstract: Objective To investigate the clinical significance of minimally invasive direct coronary artery bypass (MIDCAB). Methods 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. Results 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 p p Conclusions 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.
