    Early vessel healing of the Avantgarde cobalt-chromium coronary stent: the ON-GARDE OCT study

    Introduction: Uncoverage and malapposition of stent struts at optical coherence tomography (OCT) have been associated with stent thrombosis. Stent uncoverage by OCT is being used as a surrogate to address the propensity of a stent to develop thrombosis. We aimed to appraise early vessel healing in patients with ST-elevation myocardial infarction (STEMI) treated with the novel Avantgarde stent. Methods: Patients with STEMI and multivessel disease were enrolled. The stent deployed on the infarct-related artery was imaged by frequency domain-OCT during deferred intervention (4-7 days apart). The primary end-point was the percentage of uncovered struts. Secondary end-points were the percentage of ...
