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

Figure 6

The schema of the “RASER” technique. A: conventional 0.014-inch wire crosses the severely calcified lesion. B: microcatheter often cannot pass the lesion. C: excimer laser catheter ablates and modifies the entry of the lesion. D: this modification enables a microcatheter to pass the lesion. E: exchanging to a 0.009-inch Rota-wire from a 0.014-inch conventional wire. F: high-speed rotational atherectomy is performed.
