Background: Coronary artery bypass grafting is the gold standard in managing severe coronary artery disease. However, it is associated with prolonged recovery and potential complications . Minimally invasive coronary surgery through a small thoracotomy allows for complete revascularization with good results in graft patency. Perioperative mortality is low, and there is decreased surgical site infection rates . This meta-analysis review article discusses approaches that deliver the advantages of minimally invasive surgical revascularization. Search Method: The relevant empirical literature was identified by searching several electronic databases: PubMed and NLM Gateway (for MEDLINE), Institute of Scientific Information (ISI), SCOPUS and EMBASE , between January 1991 to May 2019 The search was performed by cross-referencing the words : minimally invasive coronary surgery , MICS , CABG or etc . The analyses were conducted with SPSS software, version 23.0. Result : The reported prevalence is presented as percent and 95% confidence interval. he search yielded 64 publications that were related to inclusion criteria. According to titles, 49 publications were excluded as clearly ineligible, leaving 5 for further review. Of these 15 studies, 13 had been reported that had significant beneficial effect of minimally invasive coronary surgery in same case than open surgery in many outcome such as earlier return to full physical function, need for blood transfusion and mortality past five years . Conclusion: To the best of our knowledge this is the first systematic review and meta-analysis that investigated minimally invasive versus conventional cardiac surgery. The results showed that minimally invasive surgery was associated with a significantly shorter stay in the ICU this is because perform through a small thoracotomy allows for complete revascularization and could reduce costs due to a shorter period spent in ICU.
