简要总结
The DESSOLVE II clinical trial is to assess the safety and performance of the sirolimus-eluting MiStent for the treatment for improving coronary luminal diameter in patients with symptomatic ischemic heart disease due to discrete de novo lesions in the native coronary arteries.

结局指标
主要结局
In-Stent Late Lumen Loss
时间窗: 9 months
Measured by the angiographic core laboratory as the difference between the post-procedure MLD in the treated segment (stented region) minus the MLD in the same region at follow-up
Major Adverse Cardiac Events (MACE)
时间窗: 9 months
Defined as death, MI (Qwave and non-Q-wave) and TVR at 9 months post-procedure. Assessed on all patients with adequate follow-up at 270 days.
次要结局
- Device Success(8 hours)
- Total Mortality(9-months)
- Target Vessel Failure (TVF)(9-months)
- Lesion Success(8 hours)
- Stent Thrombosis (Definite/Probable)(9-months)
- Procedural Success(8 hours)
- Clinically-driven Target Lesion Revascularization (TVR)(9-months)
- Total Myocardial Infarct (MI)(9-months)
