Combined Use of Excimer Laser and High-Speed Rotational Atherectomy to Overcome a Severely Calcified Lesion in Endovascular Therapy

Figure 4

Combined strategy of the excimer laser atherectomy and high-speed rotational atherectomy. (a) The excimer laser catheter (Turbo Elite 0.9 mm) also cannot cross the lesion; however, it modifies the morphology of the chronic total occlusion lesion. (b) The Caravel microcatheter can pass the lesion. (c) Exchanging to the 0.009-inch Rota-wire from the conventional 0.014-inch wire, 1.5 mm burr ablation is performed.
