Abstract：Objective To evaluate the effect of StentBoost Subtract in guiding optimized percutaneous coronary intervention in patients with bifurcation lesions. Methods Between January 2016 and June 2016, clinical data on a total of 37 consecutive patients was collected .SBS was performed using AlluraXper FD10 or FD20.The quality of the images was divided into three grades according to visualization of stent struts and guidewire: optimal(good imaging), suboptimal visualization(not good enough, but does not affect judgment ), and poor visualization(fuzzy imaging that affects judgment).Results A total of 196 images were collected and analyzed in this study. 75.6% of the patients were evaluated as of optimal visualization of stent struts and guidewire, 21.6% as of suboptimal visualization and 2.7% as of poor visualization.Conclusions As a simple and quick means of imaging , StentBoost Subtract can be used to guide optimized PCI in bifurcation lesions step by step via enhancing visualization of stents and guidewire, such as accurate stent positioning, post-dilation, rewiring of the guidewire and kissing balloon technology.
