This study aimed to compare off-pump CABG using intracoronary shunt versus the coronary clamp during distal coronary artery anastomosis.</p> <p>Methods: We conducted this randomized study between January and June 2018. We randomized 30 patients into two groups. Group A (n= 15) included patients who had coronary clamping during off-pump CABG, and Group B (n= 15) included patients who had intracoronary shunt during off-pump CABG. Study endpoints were anastomosis time and postoperative cardiac enzyme levels.</p> <p>Results: The mean age of the shunt group was higher than the mean age of the clamp group (61.06 ± 7.26 vs. 56.72 ± 12.44, respectively, p=0.03). Our study showed no statistical difference between the two groups regarding sex (p˃0.99), hypertension (p˃0.99), and diabetes (p=0.14). The distal anastomosis time was longer in the shunt group than in the clamp group (39.80±4.55 vs. 32.27±6.06 minutes, respectively, p=0.001). The postoperative troponin I (0.61±0.11 vs. 0.26±0.089 ƞg/ml, p&lt;0.001), and CK-MB levels (44.27±5.34 vs. 35.5±4.86 IU/L, p&lt;0.001) were significantly higher in the clamp group.</p> <p>Conclusion: The intracoronary shunt could be associated with lower cardiac enzyme release compared to the clamp technique. However, it was associated with a longer distal anastomosis time. </p&gt;}, number={4}, journal={The Egyptian Cardiothoracic Surgeon}, author={Salah Eldin Elsharkawe, Ehab and Mahmoud Nasser, Hend and Fathy Ali, Hosam}, year={2020}, month={Oct.}, pages={155 - 161} }
