In a recent study, researchers from the University Hospital Jean Minjoz (Besacon, France) demonstrated that optical coherence tomography (OCT) imaging can more readily visualize the coronary arteries in patients undergoing percutaneous coronary intervention (PCI) and lead to better outcomes when compared to standard angiography-guided PCI.
The study found that OCT provided useful additional information beyond that obtained solely by angiography, and impacted directly on physician decision-making. In fact, the use of OCT led to a change in procedural strategy in half of the cases.
In cardiology, the use of OCT involves introducing a miniature fiber optic catheter into the coronary artery to check vessel size, lesion traits and both stent positioning and expansion. OCT is also used in ophthalmology to assess the progression of macular degeneration, glaucoma and other ocular diseases.
