Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Procedural Success Rate: Defined as the passage of the assigned investigational device through the lesion without additional devices, achieving residual angiographic stenosis of less than 30% under TIMI 3 flow. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Acute cross-sectional area (CSA) gain: Defined as post-interventional minimum lumen area minus pre-procedural minimum lumen area. 2. Calcium Fracture Thickness: Defined as the thickness of fractured calcium measured at the edges of the fracture, as assessed by OCT. 3. Incidence of Acute Complications: Defined as coronary dissection (Type C or higher) or perforation immediately following the use of the investigational device. 4. Major Cardiovascular Events Within 9 Months Post-PCI: Defined as a composite endpoint comprising cardiac death, recurrent myocardial infarction, rehospitalization due to unstable angina or progression of angina, clinically indicated target lesion revascularization, stroke, and major bleeding. | — |
