简要总结

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).

入选标准

  • •Acute ST-Elevation Myocardial Infarction Meeting PPCI Criteria: 1) Chest pain lasting more than 20 minutes, with ST-segment elevation of at least 1 mm in two or more adjacent leads, new left bundle branch block, or evidence of posterior wall myocardial infarction; 2) Onset of symptoms within 12 hours.
  • •Patients Who Have Received Thrombolytic Therapy Within 6 Hours of Symptom Onset and Are Eligible for Rescue PCI Within 24 Hours;
  • •Infarct-Related Artery Selection Imaging and Pre-Treatment Criteria Meeting PPCI Standards: 1) De novo lesions. 2) Reference vessel diameter between 2.5 mm and 4 mm. 3) Successful pre-treatment of target lesions: post-pre-treatment residual stenosis of the culprit vessel ≤ 30%, with no type C dissections (or intravascular imaging indicating significant residual plaque burden at the site of dissection, with transverse expansion > 60°, longitudinal expansion > 2 mm, dissection involving the media or adventitia, and located at the distal end of the stent), no hematoma, and no significant thrombus (TIMI thrombus burden grade ≤ 2);
  • •Sufficient compliance with the study protocol, agreement to undertake follow-up, and coronary angiography at 9 months;
  • •Voluntary Participation in This Study, Including Signing a Written Informed Consent with Understanding of All Risks and Benefits Described in the Informed Consent Document.

研究组 & 干预措施

Drug Coated Autoperfusion Balloon Dilatation Catheter(DCAB)

Experimental

3 μg/mm² paclitaxel-coated drug-coated autoperfusion balloon dilatation catheter (DCAB). The DCAB features two radiopaque marker rings at the balloon shoulders for intravascular imaging and positioning, self-perfusion holes on the catheter shaft, and an additional radiopaque marker ring proximal to the perfusion holes to indicate their location. The catheter shaft is hydrophilically coated to facilitate blood flow through the perfusion holes when the guidewire is retracted. Preclinical studies show this design allows 15%-20% of arterial blood to reach the distal coronary artery.

干预措施: Drug Coated Autoperfusion Balloon Dilatation Catheter(DCAB) (Device)

Conventional Drug coated ballon(DCB)

Active Comparator

Bingo® PTCA Drug Delivery System: drug (paclitaxel) coated balloon (DCB) with concentration of 3 μg Paclitaxel per 1 mm2.

干预措施: Conventional Drug coated balloon (DCB) (Device)
