INTRODUCTION AND OBJECTIVES: Coronary lithoplasty (CL) is a balloon-based technique used to treat calcified lesions. This study reports the initial experience of treatment of calcified lesions with CL in an unselected and high-risk population.
METHODS: This was a prospective, multicenter registry, which included all consecutive cases with calcified coronary lesions that underwent CL between August, 2018 and August, 2019. Exclusion criteria consisted of a target lesion located in a small vessel (< 2.5mm) and the presence of dissection prior to CL. Quantitative coronary angiography and intravascular ultrasound/optical coherence tomography analysis were completed by an independent central core laboratory.
RESULTS: This registry included 57 patients (66 lesions). The population was elderly (72.6±9.4 years) with high proportions of patients with diabetes (56%), chronic kidney disease (35%), and multivessel disease (84%). All lesions were classified as type B/C. More than 75% of lesions were predilated with noncompliant/semicompliant balloons or cutting-balloon. Rotablator was used in 5 lesions (7.6%) prelithoplasty. On average, CL required 1.17 balloons delivering a mean of 60 pulses. Successful CL was achieved in 98%. In 13% of cases, lithoplasty balloon was broken during therapy. There were few procedural complications: 2 cases of significant dissections (none related to lithoplasty balloon rupture) were successfully treated with drug-eluting stent implantation. One patient experienced stent thrombosis 2 days after successfully undergoing target lesion revascularization.
CONCLUSIONS: This is a real-world multicenter registry, which supports the feasibility, safety, and short-term efficacy of PCI for calcified coronary lesions using CL in an unselected and high-risk population with promising results.
