First-in-man reported 12-months follow-up after intravascular lithotripsy in left main percutaneous revascularization

Although intravascular lithotripsy (IVL) in percutaneous coronary intervention (PCI) of severely calcified left main disease has been suggested to be effective and well-tolerated in the immediate post-intervention period, there are no data available regarding its long-term efficacy. Eight patients with high-risk left main disease (mean syntax score of 33) were treated with IVL in our center with no hemodynamic alterations or arrhythmias during the treatment. The success rate of the procedure was 100%. The major adverse cardiovascular events rate at 12 months was 12.5%, due to one case of target-lesion revascularization. There were no deaths, stroke or stent thromboses. So, after 12 months of follow-up, intravascular lithotripsy as an adjuvant to LM-PCI appears to be effective and safe.
