Improving efficiency and operator proficiency during percutaneous coronary interventions utilizing a standardized...

Area of Science:

• Cardiovascular Interventions
• Medical Imaging Technology
• Health Services Research

Background:

• Barriers to adopting optical coherence tomography (OCT) in percutaneous coronary intervention (PCI) persist.
• The LightLab (LL) Initiative aimed to evaluate a standardized OCT workflow to address these adoption barriers.
• Real-world data are crucial for assessing the clinical and economic impact of new procedural workflows.

Purpose of the Study:

• To compare the efficiency and quality of PCI procedures guided by a variable versus a standardized OCT workflow.
• To assess the impact of the LL Initiative's standardized OCT workflow on PCI outcomes.
• To determine if a standardized OCT workflow can improve PCI quality without increasing procedure duration.

Main Methods:

• A multicenter, prospective, observational study comparing baseline (variable workflow) and LL workflow phases.
• Optical coherence tomography (OCT) guided PCI procedures were analyzed for efficiency and quality metrics.
• Propensity score matching was used to control for baseline differences between the two workflow groups.

Main Results:

• Standardized LL workflow did not increase procedure time (51 min vs. 51 min).
• Significant reductions observed in radiation exposure (1124 mGy vs. 1493 mGy) and contrast volume (160 cc vs. 172 cc) with the LL workflow.
• The LL workflow decreased underexpanded lesions (34% vs. 54%) and improved minimum stent expansion (85% vs. 79%).

Conclusions:

• Standardizing OCT imaging with the LL workflow can overcome adoption barriers.
• The LL workflow improves PCI quality metrics, including stent expansion.
• Implementing a standardized OCT workflow enhances PCI outcomes without prolonging procedure time.
