What is intravascular optical coherence?

Optical coherence tomography (OCT) has opened new horizons for intravascular coronary imaging. It utilizes near-infrared light to provide a microscopic insight into the pathology of coronary arteries in vivo. Furthermore, OCT helps to monitor vessel healing after stenting.

Does optical coherence tomography optimize results of stenting?

The results of this trial indicate that OCT-guided PCI results in a better functional outcome (as assessed by post-PCI FFR) compared with routine angiography-guided PCI in patients undergoing PCI of a single lesion for NSTE-ACS.

What does IVUS stand for?

Intravascular Ultrasound (IVUS) is a catheter-based diagnostic procedure used to view the inside of a coronary artery, providing a real-time view.

Which is better optical coherence tomography or IVUS?

Despite its better resolution than that of IVUS, OCT technology has various limitations, including incomplete visualisation of the vessel wall in some lipid-rich lesions, resulting in use of smaller stents based on luminal dimensions than with IVUS and angiography.

How is optical coherence tomography used in PCI?

In the ILUMIEN I study, Optical coherence tomography imaging during percutaneous coronary intervention impacts physician decision-making: ILUMIEN I study. OCT guidance changed PCI procedural planning in 57% of cases. Surprisingly, in 31% of cases, OCT led to choice of a smaller diameter stent size than would have occurred with angiography alone.

How is optical coherence tomography used in stenting?

Nonetheless, few studies of OCT-guided stenting have been done, and OCT is not widely used for this purpose. In the ILUMIEN I study, Optical coherence tomography imaging during percutaneous coronary intervention impacts physician decision-making: ILUMIEN I study. OCT guidance changed PCI procedural planning in 57% of cases.

Which is better for PCI-intravascular or angiographic?

Intravascular ultrasound (IVUS) guidance has been shown to reduce major adverse cardiovascular events (MACE) after PCI, principally by resulting in a larger postprocedure lumen than with angiographic guidance.
