The results of the blood FV of the three bifurcation angles in the two arteries with the three stenting techniques is shown in Figure 5. The comparing group without stenting models--in the two types of arteries A and B--showed that the laminar flow was detected in the three angles of the bifurcation arteries. However, stenting techniques were applied in the arteries A and B to cause recirculatory flow at the leading edge of the LCX. The recirculatory flow became more pronounced when the bifurcation angles were increased. Among the three stenting techniques, the LCX flow velocity of the T-stenting was lower than the Culotte and Kissing. An additional low-velocity region was observed at the bifurcation carina when the Kissing bifurcation angle increased. The flow velocity of the artery A was higher than the artery B for comparing whole models. Figure 5: The results of blood flow velocity. The velocity distributions with non-stent, T-stenting, Culotte, and Kissing techniques were displayed for whole models of the artery A and artery B; (**a**) Type of artery A; (**b**) Type of artery B. The results of the wall pressure distribution of the three bifurcation angles in the two arteries with the three stenting techniques is shown in Figure 6. The comparing group without the stenting models in the two types of arteries A and B showed that the bifurcation carinal had a higher wall pressure. The higher wall pressure of the arteries A and B by T-stenting occurred on the LMCA and bifurcation carinal. The wall pressure of the artery A with T-stenting was more pronounced when the bifurcation was increased. In contrast, the wall pressure of the artery B had a reverse tendency. In the model of Culotte stenting, the higher wall pressure of the artery A was concentrated on the LMCA stent inlet and bifurcation carinal. However, as for the artery B, it was concentrated on the inlet of the LMCA and bifurcation. The higher wall pressures of the two arteries were more pronounced when the bifurcation angles were decreased. In the model of the Kissing stenting, the higher wall pressure of the artery A was concentrated on the inlet of the LMCA stent. However, as for the higher wall pressure of the artery B, both the LMCA and LCX presented with a high wall pressure. A decreased tendency of the wall pressure was discovered when the bifurcation angle was increased. Moreover, the wall pressure of the artery B was higher than the artery A for comparing whole models. The distribution of the specific low TAWSS threshold only demonstrated less than 0.5 Pa of the three bifurcation angles with the three stenting techniques in the two arteries, as shown in Figure 7. The specific low TAWSS in the artery A was wider than that in the artery B. The region of the specific low TAWSS in the artery A by the T-stenting was concentrated on the proximal site of the lateral LAD and the proximal site of the lateral LCX. In addition, the region of the specific low TAWSS was concentrated on the proximal site of the lateral LCX and the distal site of the medial LCX in the artery B. In the models of Culotte stenting, the region of the specific low TAWSS of the artery A was similarly concentrated on the proximal site of the LMCA, the proximal site of the lateral LAD, and the proximal site of the lateral LCX. However, as for the region of the specific low TAWSS of the artery B, it was concentrated on the proximal site of the lateral LCX. In the models of the Kissing stenting, the region of the specific low TAWSS of the artery A was concentrated on the proximal site of the lateral LAD, the proximal site of the lateral LCX, and the bifurcation carina. However, as for the region of the specific low TAWSS of the artery B, it was concentrated on the LCX and bifurcation carina. Moreover, the regions of the specific low TAWSS of the arteries A and B were significantly detected to increase tendency when the bifurcation angles of the artery were enlarged.
