In Wellington Hospital, CABG is being performed by various techniques like OPCAB, On‐pump cardioplegic arrest, fibrillatory arrest and On‐pump beating heart. Aim This study was undertaken to compare morbidity and mortality between On‐ pump CABG and OPCAB on basis of Euroscore. Material and Method From January 2003 till December 2004, data were collected according to Australasian society of Cardiothoracic surgery data set. Euroscores were calculated and patients were divided into 3 groups. Results of OPCAB and On‐pump CABG were compared on basis of Euroscore group. In this period we performed 350 On‐pump CABG and 254 OPCAB. Results OPCAB group had less number of grafts per patients. Even for triple vessel disease numbers of grafts were lower in OPCAB group. OPCAB group had more patients with total arterial revascularization. There were 10 deaths in On‐pump group and 1 in OPCAB group. In the low and moderate risk group there was no significant difference in hospital stay, ventilation hours and ICU stay. However inotropic requirement and requirements of blood products were less in OPCAB group. There was no statistically significant difference between Incidence of new renal failure or arrhythmia in two groups. 2 patients in each group had blocked graft in immediate postop period and required revascularization. There were only 5 patients in the high‐risk group in OPCAB making intergroup comparisons difficult. Conclusion OPCAB does not offer any significant advantage in terms of mortality and morbidity over On‐pump CABG. To evaluate the effects of number of grafts and total arterial revascularization, it needs a long‐term follow‐up.
