Intravascular Imaging as a Performance Measure for Percutaneous Coronary Intervention
Authors' conclusion
IVI use for PCI is increasing rapidly at Veterans Affairs hospitals in the United States but with marked variation at the hospital and physician levels. IVI meets established criteria for an effective performance measure and should be measured and reported by local and national organizations to encourage further uptake. Ongoing training and quality improvement may be required to maximize the benefit of IVI as it is more widely utilized.
