Minimally invasive coronary artery bypass grafting is associated with improved clinical outcomes.

Objective: Minimally invasive coronary artery bypass grafting (MICS CABG) via left minithoracotomy is an alternative to off-pump coronary artery bypass (OPCAB) via sternotomy. Our objective was to evaluate the clinical outcomes after MICS CABG versus OPCAB.

Methods: The medical records of patients who underwent MICS CABG from December 2009 to December 2011 and OPCAB from January 2005 to April 2011 were reviewed.
