“…Although the two-stent strategy is more demanding in terms of the operator learning curve, fluoroscopy time, amount of contrast used, and structural changes of the lesion during the procedure, there are situations where the use of two stents should be considered as the first option, like cases with > 2 mm diameter side branches, significant obstructive lesions > 70% in the origin of the side branch, diffuse lesions (> 20 mm) involving the origin and third proximal of the side branch, and left coronary artery main trunk lesions. The most relevant angioplasty techniques involving two stents are skirt, T stenting, TAP, culotte, V stenting, Y stenting, Crush, and DK-Crush, using for the planning of the procedure the MADS (main, across, distal, and side) classification that presents stenting procedures step by step, depending on the technique chosen 3,5 .…”
