Review compares efficacy of functional and anatomical imaging methods in coronary artery disease, highlighting novel technologies.
Percutaneous Coronary Intervention (PCI) has advanced significantly with the incorporation of imaging and physiology assessment techniques. Fractional Flow Reserve (FFR) and Non-Hyperemic Pressure indices (NHPIs) provide information regarding the functional significance of coronary lesions, while Intravascular Ultrasound (IVUS) and Optical Coherence Tomography (OCT) enhance anatomical characterization and guide stent implantation. This review explores the implementation of physiology- and imaging-guided strategies in clinical practice, comparing their efficacy and limitations. Novel technologies now allow for physiology estimation without hyperemic agents, and hybrid techniques, such as OCT-derived FFR, are increasingly integrated into clinical practice. These approaches offer the combined advantages of functional assessment and detailed anatomical imaging.
