Abstract Background  The aim of this study was to assess the safety and effectiveness of intravascular lithotripsy (IVL) in treating eccentric calcified coronary lesions. Methods  Between December 2015 and March 2019, 180 patients were enrolled in the Disrupt CAD I and CAD II studies across 19 sites in 10 countries. Patient-level data were pooled from these two studies (n = 180), within which 47 eccentric lesions (26%) and 133 concentric lesions were identified. Results  Clinical success, defined as residual stenosis
