In this study, we examined the early results for patients who underwent beating heart coronary bypass surgery and compared these results with those of conventional coronary bypass surgery.
A total of 1094 patients who underwent isolated coronary artery bypass surgery between January 2009 and December 2011 in our clinic were included in this study. Seventy-three patients in whom cardiopulmonary bypass was not used (group 1) were compared to 1021 patients in whom cardiopulmonary bypass was used (group 2).
The mean age was 60.7 ± 9.3 in group 1 and 58.9 ± 9.7 in group 2 (P > 0.05). There was no signifi cant difference between the two groups in terms of gender, or the coexistence of diabetes mellitus (DM), chronic obstructive pulmonary disease (COPD), and hypertension (P > 0.05). There was no significant difference between group 1 and group 2 in terms of development of postoperative atrial fibrillation (AF), use of an intra-aortic balloon pump, need for re-operation for bleeding, or duration of hospital stay and intensive care unit stay (P > 0.05). The need for inotropic support and the amount of mediastinal drainage were less in group 1 than in group 2 (P = 0.002, P < 0.001). The incidences of postoperative cerebrovascular accident, development of chronic renal failure, and sternal wound infection did not signifi cantly differ between the groups (P > 0.05). There was no mortality in group 1, whereas it was calculated as 1.8% in group 2 (P = 0.63).
Beating heart coronary artery bypass surgery decreases the need for inotropic support and transfusion.
