What this trial studies

This study assesses the clinical efficacy of the stent-balloon-stent (SBS) technique for treating complex coronary bifurcation lesions. The SBS approach involves implanting a stent in the side branch followed by a stent in the main vessel, utilizing a drug balloon to ensure optimal opening of the side branch. Patients will undergo coronary angiography before and 6-12 months after the procedure to evaluate outcomes such as stenosis rate and target vessel failure. The study aims to compare the SBS technique's effectiveness against existing double stent strategies.

Who should consider this trial

Good fit: Ideal candidates include patients with evidence of myocardial ischemia and specific bifurcation lesion characteristics who can tolerate long-term antiplatelet therapy.

Not a fit: Patients with severe surgical contraindications or those who have previously undergone stent implantation for related lesions may not benefit from this study.

Why it matters

Potential benefit: If successful, this technique could improve long-term outcomes for patients with complex coronary bifurcation lesions.

How similar studies have performed: While the SBS technique is a novel approach, existing studies on bifurcation lesions have shown varying degrees of success with different stenting strategies.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* There is evidence of myocardial ischemia, such as coronary angiography, including patients with stable angina pectoris, unstable angina pectoris, asymptomatic myocardial ischemia and acute myocardial infarction (\> 24 hours).
* All bifurcation lesions were Medina 1, 1, 1 or 0, 1, 1 with reference vessel diameter (RVD) in the SB ≥2.5 mm by visual estimation and had to meet DEFINITION criteria of complex bifurcations
* Patients who can tolerate long-term antiplatelet therapy
* None of the vessels related to bifurcation lesions have received stent surgery
* Patients who agree and sign an informed consent form

Exclusion Criteria:

* Patients who are unwilling to sign the relevant informed consent form
* Patients with severe surgical contraindications
* Life expectancy of patients is less than 12 months
* Patients who have previously undergone stent implantation or surgical coronary artery bypass grafting for related lesions
* Patients with severe hepatorenal insufficiency
* Heart failure patients with NYHA grade ≥ Ⅲ
* Patients who are scheduled for surgery requiring antiplatelet medication interruption within 6 months
* Patients who need chronic oral anticoagulation
* Any clinical condition of the patient may interfere with medication compliance or long-term follow-up
* Pregnant or breastfeeding women
