Intravascular Imaging During PCI
Introduction
- Due to angiography limitations, intra-coronary imaging can be used to guide coronary stent implantation, especially in patients with left main coronary artery involvement or complex lesions.[1]
- Intravascular ultrasound (IVUS) and optical coherence tomography (OCT are two imaging methods that can be used to assess vasculature conditions before and after PCI.
- Both imaging methods can assist in evaluating the need for lesion preparation, stent sizing, diminishing geographic-related errors, confirming stent expansion, identifying complications, and causes of stent failure.[2]

ACA 2021 Revascularization Guideline
| Class 2a Recommendation, Level of Evidence: B-R[1] |
| 1.Intravascular ultrasound (IVUS) can be used as a procedural guidance in patients undergoing coronary stent implantation, particularly in those with left main or complex coronary artery stenting in order to diminish ischemic events.
2.Optical coherence tomography (OCT is a reasonable alternative to IVUS as an procedural guidance in patients undergoing coronary stent implantation, except in those with ostial left main disease. |
| Class 2a Recommendation, Level of Evidence: C-LD[1] |
| If stent failure occurs, both IVUS and OCT can be used to determine the mechanism of stent failure. |
Intravenous Ultrasound
Intravenous Ultrasound
- Multiple meta-analyses have shown that intravascular ultrasound-guided PCI is more successful in reducing major adverse cardiovascular events (MACE) compared to angiographic-guided PCI.[3][4][5][6][7]
- Furthermore, based on a trial named ULTIMATE (Intravascular Ultrasound Guided Drug Eluting Stents Implantation in “All-Comers” Coronary Lesions), intravascular ultrasound-guided PCI is more successful in reducing target-vessel failure compared to angiographic-guided PCI.[8]
- The following are the list of pre-PCI evaluations that can be done with intravascular ultrasound:[9][10]
- Full-thickness evaluation of the vessel wall
- Plaque burden
- Calcification extent
- Length of lesion
- External elastic lamina diameter for stent sizing
- The following are the list of post-PCI evaluations that can be done with intravascular ultrasound:[9][10]
Optical Coherence Tomography
Optical Coherence Tomography
- Optical coherence tomography (OCT) is capable of generating high-resolution images of vessel walls by using infrared light. This imaging method has particular advantages in the evaluation of the following:[2]
- Calcium thickness
- Lipid, thrombus, fibroatheroma, and plaque rupture
- Stent strut neointimal thickness
- Stent malposition
- Edge dissections
- The following are some of the limitations of optical coherence tomography (OCT):[1]
