The study will include a total of 170 patients with calcified coronary lesions who will be treated with pulsed sonic balloon dilatation catheter and pulsed sonic generater. Optical coherence tomography (OCT) imaging subgroups of 30 patients were designed in 1-2 centers to further accurately assess the treatment effect of calcified lesions.
The prospective, multicenter, single- arm study is designed to verify the safety and efficacy of pulsed sonic balloon dilatation catheter and pulsed sonic generater in the treatment of coronary calcification lesions.
