Intravascular lithotripsy (IVL) has shown safety and efficacy in treating severe coronary calcification in prior studies. This study aimed to assess the safety and effectiveness of IVL using domestically produced balloons for the treatment of calcified de novo coronary lesions in Chinese patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The VIGOUR trial (NCT05818098) was a prospective, multicenter, single\u2010arm study designed to obtain approval for coronary IVL in patients with severe coronary calcification. The primary endpoint was procedural success. Secondary endpoints included device success, angiographic success, 30\u2010day major adverse cardiovascular events (MACE) incidence, and procedure\u2010related serious complications. An optical coherence tomography (OCT) sub\u2010study was conducted to assess the mechanisms and predictors of calcium modification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 189 patients were enrolled.

At the secondary endpoints, device success was achieved in 98.9% of patients, and angiographic success in 98.4%. The 30\u2010day MACE incidence was 5.3%, and procedure\u2010related serious complication was 0.5%. 81.9% (59\/72) of lesions exhibited OCT\u2010identified multi\u2010plane and longitudinal calcium fractures after IVL. Multivariable analysis revealed that calcium angle was associated with OCT\u2010identified calcium fractures.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>IVL using domestically produced balloons significantly improves vessel compliance, facilitating successful stent delivery and deployment.
