Objectives: This study was aimed to analyze the results of off-pump coronary artery bypass grafting (OPCABG) in patients with significant left main coronary artery disease (LMCA) versus patients without LMCA disease.
Methods: A retrospective and prospective study was conducted from January 2011 to December 2014. A total of 140 propensity matched patients who underwent OPCABG were included in our study; 70 with significant LMCA disease versus 70 in non-LMCA group. Patient demographics and preoperative co-morbidities were recorded. Intra-operative and post-operative parameters were analyzed. Statistical analysis was done and p-values less than 0.05 were considered significant.
Results: In both the groups (LMCA vs. non-LMCA) of patients undergoing OPCABG, patients parameters and co-morbidities were matched. Intra-operatively, there was no significant differences in the number of distal grafts (p = 0.21), revascularization percentage (96% vs 97%). No significant difference was observed in post-operative parameters like ventilatory time (p=0.68); ICU stay (p=0.72); myocardial infarction (p=0.62); reoperation for bleeding (3% vs 3%); cerebral stroke (p=0.79); hemodialysis (p=0.76) and arrythmias (p=0.91). There was equivocal mortality (2.8% vs.4.2%; p=1.00).
Conclusions: OPCABG is a safe, effective and feasible method of coronary revascularization in patients with significant LMCA disease.
