Points

  • The AGENT IDE trial evaluated the efficacy of a paclitaxel-coated balloon compared to an uncoated balloon for 1-year target lesion failure in patients with in-stent restenosis undergoing percutaneous coronary intervention.
  • Target lesion failure was significantly lower in the paclitaxel-coated balloon group (17.9%) compared with the uncoated balloon group (28.6%), indicating the superiority of the paclitaxel-coated balloon in reducing adverse outcomes.
  • Ischemia-driven target lesion revascularization and target vessel myocardial infarction occurred less frequently after treatment with a paclitaxel-coated balloon, further supporting its effectiveness in managing coronary in-stent restenosis.
  • The study, conducted at 40 centers across the United States and involving 600 patients, demonstrated that paclitaxel-coated balloons offer a beneficial treatment strategy for patients with in-stent restenosis undergoing coronary angioplasty.
  • Overall, the findings from the AGENT IDE trial provide strong evidence for the superiority of paclitaxel-coated balloons over uncoated balloons in reducing adverse cardiovascular events and target lesion failure in patients with coronary in-stent restenosis.

Summary

In a multicenter randomized trial involving 600 patients with in-stent restenosis, the efficacy of a paclitaxel-coated balloon compared to an uncoated balloon for 1-year target lesion failure in patients undergoing percutaneous coronary intervention was evaluated. The study found that target lesion failure was significantly lower in the paclitaxel-coated balloon group (17.9%) compared with the uncoated balloon group (28.6%) (P = .003). Additionally, ischemia-driven target lesion revascularization and target vessel myocardial infarction occurred less frequently after treatment with a paclitaxel-coated balloon. The primary endpoint of 1-year target lesion failure, defined as the composite of ischemia-driven target lesion revascularization, target vessel-related myocardial infarction, or cardiac death, was met with superiority in the paclitaxel-coated balloon group.

The AGENT IDE trial, conducted at 40 centers across the United States, enrolled 600 patients with in-stent restenosis and completed a one-year clinical follow-up. The primary endpoint at one year occurred in 17.9% of the paclitaxel-coated balloon group vs 28.6% in the uncoated balloon group, meeting the criteria for superiority. Target lesion revascularization and target vessel-related myocardial infarction occurred less frequently among patients treated with a paclitaxel-coated balloon. The study concluded that among patients undergoing coronary angioplasty for in-stent restenosis, a paclitaxel-coated balloon was superior to an uncoated balloon concerning the composite endpoint of target lesion failure, thus offering an effective treatment option for patients with coronary in-stent restenosis.

In summary, the findings from the AGENT IDE trial provide evidence that treatment with a paclitaxel-coated balloon offers an effective treatment strategy for the management of coronary in-stent restenosis, demonstrating superiority over uncoated balloons in reducing target lesion failure, ischemia-driven target lesion revascularization, and target vessel-related myocardial infarction.
