Abstract
Objectives: Intravascular lithotripsy (IVL) clinical efficacy and safety in the treatment of calcified coronary artery disease (CAC) is not well known. We sought to assess IVL safety and efficacy in CAC. Methods: A comprehensive online databases search were performed to identify intravascular lithotripsy studies in patients with coronary artery disease. The primary outcome was IVL related change in the mean pre and post-procedural diameter of the coronary artery. Results: A total of 4 studies with 282 patients were included. The mean pre-IVL coronary diameter for all patients was 1.01 mm, while the mean post-IVL coronary diameter was 2.70 mm. The mean pre-post IVL diameter difference of coronary arteries on the pooled analysis was significantly lower by 4.08 mm (95% CI -4.94 to -3.30, p ≤ 0.00001). The Overall increase in the post-IVL lumen diameter was significantly higher than the pre-IVL diameter with a mean difference of -4.16 (95% CI -5.08 to -3.24, p = 0.000001). However, compared to pre-IVL, there was a significant reduction in the overall mean difference of luminal calcium angle after IVL of the stented coronary arteries (0.09, 95% CI 0.002-0.16, p = 0.01). Conclusion: Intravascular lithotripsy can offer a significant improvement in the vessel lumen to facilitate coronary stent delivery and deployments in severely calcified coronary arteries.
