CORONARY STRUCTURE High-end Class I Compatible Operating procedure I Rotablation DCA Vascular rupture CTO High-end Class I Compatible Operating procedure I CAG IVUS / OCT FFR Stenting Rotablation Bifurcation This is a chronic total occlusion (CTO) disease model. It features multiple collateral channels between LAD and RCA (including septal branch and apex routes), and between LCX and RCA (including AV groove and apex routes). The LAD, LCX and RCA have their own pockets, so that if the CTO vessel part is set in the RCA pocket, both the antegrade approach from RCA and the retrograde approach from LAD can be simulated, and vice versa. BIF model can facilitates the full procedures around LM (left main) bifurcation and LAD-Dx (diagonal branch) bifucarion strategies. Let’s try T-stenting, Culotte, Crush, KBT and whatever you want!
