We conducted this study to Comparison rewiring of side branch though onyx versus XIENCE stents and evaluated the correlation of their structural design (cell size and thickness) with time of fluoroscopy and the amount of Dye. Material and Method: 85 CAD patients referred to Modarres Hospital from May 2016 to May 2017 with bifurcation lesion after angiography, were divided randomly into two groups after recording the demographic characteristics and also data about the involved arteries and in each group separate commercial stents including xeince and onyx stents were used for rewiring. Both groups were rewired by a technician and the amount of consumed dye, time of fluoroscopy and the stent properties including length and diameter were separately recorded. No significant correlation was seen between the length and diameter of xience and onyx stents with Dye and time of fluoroscopy. There was significant negative correlation between branch size with Dye and time of fluoroscopy. In onyx group, there was a negative significant correlation between Dye and time of fluoroscopy with angle branch and severity of ostium (stenosis), in xeince group, there was a negative significant correlation between Dye and time of fluoroscopy with branch angle. Although in the present study there was no significant differences between the two groups for evaluated indices, but it seems that follow-up of patients for mortality rate, heart attack re-requirement to angiography and surgery in different periods of time, can be helpful in order to assessment of more appropriate stent.
