Baseline V-RESOLVE Score Guided Stent Implantation in Coronary Bifurcation Lesions
Study Details
Study Description
Brief Summary
The purpose of this study is to investigate if baseline V-RESOLVE score-guided PCI is associated with significant reduction of side branch occlusion rate compared to angiography-guided PCI in patients with coronary bifurcation lesions.

Detailed Description
A number of 1104 patients scheduled for elective percutaneous coronary intervention (PCI) with native coronary bifurcation lesions suitable for stent implantation are included in the present study. This study will be conducted in two stages with 552 patients each. In the first stage, all patients receive angiography-guided PCI. In the second stage, all patients receive PCI under the guidance of baseline V-RESOLVE score.

---|---|
Experimental: Baseline V-RESOLVE score-guided PCI Lesions with baseline V-RESOLVE <14 scores would undergo either jailed wire technique (diameter of side branch [SB]<2.5mm and ≥2.0mm) or provisional two-stent strategy (diameter of SB≥2.5mm); Lesions with baseline V-RESOLVE ≥14 scores would undergo either jailed balloon technique (diameter of SB<2.5mm and ≥2.0mm) or elective two-stent strategy (diameter of SB≥2.5mm). |
Procedure: Baseline V-RESOLVE score-guided PCI
Jailed wire technique (JWT): Both main vessel (MV) and side branch (SB) are wired. The MV is stented with wire protection in SB. If suboptimal results exist, the SB would be rewired and a kissing balloon inflation (KBI) is undertaken.
Jailed balloon technique: A monorail balloon is advanced into the SB. If there is TIMI flow grade decrease in the SB after MV stenting, the SB balloon is inflated to simulate attempt to reopen the SB. The procedure would be completed with the standard KBI whatever the situation is.
Provisional two-stent strategy: Lesion preparation and MV stenting are consistent with JWT. Provisional SB stenting could be undertaken when suboptimal results occur after SB rewiring and a KBI is undertaken.
Elective two-stent strategy: Patients in this subgroup would undergo crush procedure or any other elective two-stent strategy which stenting SB before MV stenting.

Outcome Measures
Primary Outcome Measures
- side branch occlusion after main vessel stenting [Immediately after the main vessel]
The primary endpoint is side branch occlusion, which is defined as any decrease in TIMI flow grade or absence of flow in side branch after main vessel stent well opposed.
Secondary Outcome Measures
- The elevation of biomarkers of peri-procedural myocardial injury [Creatine Kinase-Myocardial Band (CK-MB) and Troponin I]. [48h after Percutaneous Coronary Intervention (PCI)]
Peri-procedural Myocardial Infarction (MI) is defined as biomarkers elevation ≥10 × upper reference limit (URL) for CK-MB and/or ≥70 × URL for troponin.
- Major adverse cardiac events (MACE) [12-month follow-up]
Including all cause death, all myocardial infarction (MI) and target vessel revascularization
