简要总结
The trial aims to evaluate the long-term clinical outcome of the DCB-only technique is non-inferior to the provisional T stenting with DES in the patients who have 'true' bifurcation lesions.

入选标准
- •At least 18 years old;
- •Evidence of myocardial ischemia and indications of PCI, stable or unstable angina pectoris, or old myocardial infarction;
- •Primary and bifurcated coronary artery lesions (Medina classification 1,1,1 or 1,0,1 or 0,1,1);
- •Visual angiography of the main branch reference vessel diameter ≥2.5mm, and ≤4.0mm;Branch reference vessel diameter ≥2.0mm;
- •Diameter stenosis of main and branch lesions ≥ 70%, and diameter stenosis of branch lesions ≥ 50%;
- •Visual examination of residual stenosis of main branch lesions after pre-dilation ≤ 30% without vascular dissection or dissection with NHLBI classification A, B, C type.
- •If 2 bifurcation lesions meet the inclusion requirements, only 1 lesion can be included in the study, and the other lesion can be treated or not treated as a non-target lesion.
排除标准
- •Main branch or branching target lesions require treatment with more than one device (DES or DCB);
- •There is more than 1 non-target lesion requiring intervention on the target blood vessel;
- •The distance between non-target lesion and target lesion is less than 10 mm;
- •Main and branch lesions > 26 mm or branch lesions length BBB> mm;
- •Left main lesion and its bifurcation lesion;
- •Intra-stent restenosis or severe calcification;
- •ST-segment elevation or non-ST-segment elevation myocardial infarction 7 days before surgery;
- •Severe heart failure (NYHA-IV or left ventricular ejection fraction <35%);
- •Cardiogenic shock;
- •known to have renal failure (EGFR <30ml/min/1.73m2);
- •Pregnant or lactating women, or women of reproductive age who had family planning or were unable to take adequate contraceptive measures during the study period;
- •Any known allergic reactions or contraindications to the drug and coating or scaffold metal required for DCB in the study;
- •Other DES or DCB treatment contraindications;
- •Failing to sign an informed consent or having an expected life of less than 12 months;
- •Other researchers consider it inappropriate to participate in this study.
