Data regarding IVL clinical utility for PAD remain sparse. We aimed to evaluate the safety and efficacy of IVL in managing calcified PAD. Methods: A comprehensive literature search (PubMed and Embase) through November 2020. Studies evaluating the clinical outcomes of IVL use in the management of calcified PAD. Primary outcomes: IVL delivery success rate, pooled mean of acute lumen gain, minimal lumen diameter (MLD), and residual stenosis. Secondary outcomes: 30- day major adverse effects (MAEs), (dissection, perforation, thrombus formation, and distal embolization rates).Meta-analyses were conducted using a random-effect model. Results: 7 studies (503 patients; 605 lesions). IVL success rate=99.6% (95% CI: 0.991-1.002). Pooled mean acute lumen gain=2.745 mm (95% CI: 1.826-3.664). Minimal diameter (MLD)= 4.017 (95% CI: 2.910-5.123). Mean residual stenosis (MRS) = 21.737 mm (95% CI: 17.749-25.724).30-day MAE rate=0.018 (95% CI: -0.002-0.038), including dissection rate = 0.03 (95% CI: -0.003-0.047) and perforation rate = 0.004 (95% CI: -0.001-0.009). No studies reported embolization or thrombus formation. Conclusion: IVL is an effective and safe technique in managing calcified PAD, achieving significant improvement of acute lumen gain and low 30-day MAEs. However, further studies with large sample sizes are needed to determine the long-term efficacy and safety of IVL in PAD. https://dx.doi.org/10.46570/utjms.vol11-2023-717 https://dx.doi.org/10.46570/utjms.vol11-2023-717 mailto:Omar.Sajdeya@utoledo.edu
