Summary
The subintimal tracking and re-entry technique (SB-STAR) effectively treats stent-jailed side branch occlusion after percutaneous coronary intervention. This bailout strategy demonstrated excellent 6-month patency and favorable clinical outcomes in patients.
Area of Science:
- Interventional Cardiology
- Vascular Surgery
- Medical Devices
Background:
- Stent-jailed side branch occlusion is a complication of percutaneous coronary intervention (PCI).
- Conventional methods may not successfully recanalize occluded side branches.
- There is a need for effective bailout strategies for these complex cases.
Purpose of the Study:
- To evaluate the clinical effectiveness and outcomes of the subintimal tracking and re-entry (SB-STAR) technique.
- To assess SB-STAR as a bailout strategy for stent-jailed side branch occlusion.
- To analyze technical success, angiographic, and clinical outcomes at 6-month follow-up.
Main Methods:
- Retrospective analysis of patients undergoing elective PCI treated with SB-STAR.
- SB-STAR was used for severe stenosis, reduced flow, or ischemic signs.
- Technical success, 6-month angiographic patency, and clinical events were analyzed.
Main Results:
- SB-STAR was performed in 10 patients out of 13,431 PCI procedures.
- 100% angiographic success rate was achieved during the procedure.
- At 6 months, 80% of patients had confirmed side branch patency with no deaths or target-vessel revascularizations.
Conclusions:
- SB-STAR serves as an effective bailout strategy for stent-jailed side branch occlusion.
- The technique provides good patency and favorable clinical outcomes at 6-month follow-up.
- SB-STAR improves outcomes in complex PCI complications.
