Brief Summary
BACKGROUD: Percutaneous coronary intervention (PCI) is increasingly used to treat unprotected left main coronary artery stenosis. Protected LM PCI is considered standard of care in most centers. OCT allows for precise determination of stent placement, stent expansion and apposition. The pattern of vessel healing can be very precisely studied if immediate post-stent implantation OCT/IVUS data is compared to the 6-month post-PCI interval. While OCT cannot be optimally used for ostial lesion imaging, IVUS can be used to image ostial lesions/stent placement. Optimal and consistent vessel healing is particularly important in LM PCI where stent thrombosis is a potential complication with serious adverse outcome. HYPOTHESIS: Due to the absorption of the polymer of the Boston Scientific Synergy Stent over time, early strut coverage patterns and timeline may be different than previously observed in DES and BMS stents in LM PCI. Late acquired stent malapposition (LASM) is expected to differ from previous observations with traditional DES/BMS. Stent coverage in LM PCI will be studied with OCT or IVUS at six and 12 months and compared to OCT or IVUS at the time of stent implantation. OCT/IVUS data will be analyzed in a core lab (CRF) and correlated with clinical outcomes at 6 and 12 months.

Outcome Measures
Primary Outcomes (1)
The Stents Analyzed for Strut Coverage in LM Percutaneous Coronary Intervention (PCI)
The stents from 6 participants were analyzed for strut coverage, which is specifically defined as Percentage of Uncovered Stent Struts. The Percentage of Uncovered Stent Struts is the number of struts without distinct overlying tissue, in which the luminal reflection of the strut surface is directly interfacing with the lumen, divided by total number of analyzable struts.

Study Arms (1)
Optical Coherence Tomography
OTHERPatients who have undergone clinically-indicated PCI of LM where OCT was performed as part of the routine index procedure will be approached for the study and enrolled if eligible.
Interventions
OCT will be performed with the St. Jude OCT system. Detection of metallic stent struts will be performed automatically with manual adjustments made as necessary. Stent area tracings will be automatically performed by interpolated contours connecting the center point of the luminal surface of each detected metallic strut. Stent expansion will be determined as the minimum stent area divided by the average reference lumen area and presented as a percentage. Neo-intimal hyperplasia (NIH) area will be determined in follow-up examinations as the area between the stent and lumen contours. Incomplete stent apposition (ISA) area will be determined as the area between the stent contour and the lumen contour at the site of malapposed struts, in a region not overlying a side branch ostium.
Eligibility Criteria
You may qualify if:
- Age 18 years or greater;
- Left Main CAD, defined as ≥ 50% diameter stenosis and amenable to re-vascularization by PCI;
- Willing and able to give informed consent. The patients must be able to comply with study procedures and follow-up.
- Ability to comply with minimum of 6 months of DAPT after the index procedure.
- Unprotected Left Main PCI
- Protected Left Main PCI
You may not qualify if:
- Coexisting conditions that limit life expectancy to less than 12 months or that could affect patient's compliance with the protocol;
- Serum creatinine greater than 2.0 mg/dL;
- Cardiogenic shock;
- STEMI;
- Non-STEMI, if the cardiac troponin is not stable or starting to decline;
- Pregnancy;
- Inability to take dual antiplatelet therapy for 6 months;
- Any target lesion with previously placed stent.
- Patients disqualified for CABG surgery.
- Contraindications for OCT use:
- Bacteremia or sepsis
- Major coagulation system abnormalities
- Severe hemodynamic instability or shock
- Patients diagnosed with coronary artery spasm
- Acute renal failure
