High-Definition Intravascular Ultrasound Versus Optical Coherence Tomography: Lumen Size and Plaque Morphology

Video Transcription

Video Summary

This panel discussion centers on a key study comparing the latest high-definition intravascular ultrasound (HDI) and optical coherence tomography (OCT) technologies for assessing coronary artery lumen size and plaque morphology. The study, led by Dr. Ioannis Tsitsitsis, found that HDI slightly overestimates lumen size while OCT underestimates it, with HDI showing greater accuracy against micro-CT ground truth in silicon models. Importantly, newer software advancements, like Boston Scientific’s Avigo+ system, have improved the accuracy, reproducibility, and automation of measurements, reducing subjective eyeballing. Experts emphasize that both HDI and OCT now provide highly compatible and reliable imaging, with OCT better visualizing fine structures such as thin fibrous caps. These advances are fostering greater confidence in intravascular imaging, promoting its wider adoption in clinical practice. The consensus highlights a future where automated, precise intravascular imaging enhances decision-making and patient care, moving away from estimations towards true precision medicine.
