Evaluating the Safety and Efficacy of Drug-Coated Autoperfusion Balloons Versus Conventional Drug-Coated Balloons Guided by IVUS-OCT Multimodal Imaging for Treating Acute Myocardial Infarction: OPERA-AMI Study

Официальное название

An Open-Label, Prospective, Single-Center, Randomized Controlled Trial Evaluating the Safety and Efficacy of Drug-Coated Autoperfusion Balloons Versus Conventional Drug-Coated Balloons Guided by IVUS-OCT Multimodal Imaging for Treating Acute Myocardial Infarction: OPERA-AMI Study

Обзор

Trial Goals: 1. Evaluation of Mid- to Long-Term Safety and Effectiveness of Drug-Coated Autoperfusion Balloon Dilatation Catheter (DCAB) versus Conventional Drug coated balloon (DCB) in Patients with ST Segment Elevation Myocardial Infarction (STEMI). 2. Evaluation of Hybrid IVUS-OCT System for Intraoperative Evaluation of DCAB or Conventional DCB Treatment Safety and Effectiveness for De Novo Lesions During Emergency Percutaneous Coronary Intervention (PCI) in Patients with STEMI. The primary outcome is late lumen loss (LLL) assessed at 9 months following emergency PCI, measured using quantitative coronary angiography (QCA).
