Cardiology Conference-CVC 2026

Coronary physiology forms the backbone of accurately assessing the functional significance of coronary artery lesions and informing intervention strategies. Techniques like fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) go beyond what’s visible on traditional angiography by directly measuring blood flow and pressure gradients across stenotic segments. Rather than simply identifying anatomical narrowing, FFR and iFR determine which lesions are actually compromising myocardial perfusion.

FFR, which requires vasodilator administration to gauge maximal blood flow, offers nuanced data on lesion severity; iFR, in contrast, provides a resting index without the need for pharmacologic agents, streamlining the assessment process. These physiological tools enable clinicians to make evidence-based decisions about revascularization—whether to pursue percutaneous coronary intervention (PCI) or opt for conservative medical management.

Applications are broad: guiding PCI, optimizing stent placement, clarifying the significance of borderline lesions, and ultimately aiming to improve patient outcomes. By combining physiological measurements with imaging, interventional cardiologists can personalize therapy, avoid unnecessary stenting, and minimize procedural risks. Mastery of coronary physiology is now an essential component of precision-guided cardiac care, ensuring that interventions are both appropriate and effective, positively impacting both short- and long-term cardiovascular health.
