  •  OBJECTIVE  To assess the safety and effectiveness of intravascular lithotripsy (IVL) treatment for de novo coronary lesion involving severely calcified vessels in a Chinese population.  METHODS  The Clinical Trial of the ShOckwave Coronary IVL System Used to Treat CalcIfied Coronary ArtEries (SOLSTICE) was a prospective, single-arm, multicentre trial. According to the inclusion criteria, patients with severely calcified lesions were enrolled in the study. IVL was used to perform calcium modification prior to stent implantation. The primary safety endpoint was freedom from major adverse cardiac events (MACEs) at 30 days. The primary effectiveness endpoint was procedural success, defined as successful stent delivery with residual stenosis < 50% by core lab assessment without in-hospital MACEs. The morphological changes of calcium modification were assessed by optical coherence tomography (OCT) before and after IVL treatment. RESULTS  Patients (n = 20) were enrolled at three sites in China. Severe calcification by core lab assessment was present in all lesions, with a mean calcium angle and thickness of 300 ± 51° and 0.99 ± 0.12 mm (by OCT), respectively. The 30-day MACE rate was 5%. Both primary safety and effectiveness endpoints were achieved in 95% of patients. The final in-stent diameter stenosis was 13.1% ± 5.7% with no patient had a residual stenosis < 50% after stenting. No serious angiographic complications (severe dissection grade D or worse, perforation, abrupt closure, slow flow/no-reflow) observed at any time during the procedure. OCT imaging demonstrated visible multiplane calcium fracture in 80% of lesions with a mean stent expansion of 95.62% ± 13.33% at the site of maximum calcification and minimum stent area (MSA) of 5.34 ± 1.64 mm2.  CONCLUSIONS  The initial coronary IVL experience for Chinese operators resulted in high procedural success and low angiographic complications consistent with prior IVL studies, reflecting the relative ease of use of IVL technology.
