Integrating IVUS Catheters Into Modern Hybrid Imaging Approaches
Hybrid imaging is becoming increasingly popular in cardiovascular care, combining different diagnostic tools to improve accuracy. IVUS catheters are a cornerstone of these hybrid approaches, especially when paired with angiography, OCT (optical coherence tomography), or physiological measurements such as FFR (fractional flow reserve).
Each imaging method provides a unique perspective. Angiography shows lumen outlines, OCT provides high-resolution surface imaging, and FFR evaluates functional significance. IVUS offers cross-sectional views of vessel walls and plaque composition. When used together, clinicians gain a comprehensive understanding of lesion characteristics.
For example, angiography may suggest a moderate blockage, but IVUS can reveal significant plaque burden that warrants treatment. Similarly, IVUS can validate OCT findings by assessing deeper plaque layers, especially calcium. In scenarios where contrast dye needs to be minimized, IVUS provides reliable imaging without relying on contrast injection.
Hybrid imaging enhances decision-making, especially in complex cases like bifurcation lesions, calcified arteries, and left main disease. IVUS helps confirm wire position, guide stent sizing, and evaluate final results, while physiological measurements ensure that the intervention actually improves blood flow.
As cardiovascular interventions evolve, combining IVUS with other imaging tools enables a more comprehensive and safer approach to patient care. This synergy ultimately delivers higher accuracy and better outcomes.
