Clinical Utility and Significance of Intravascular Ultrasound and Optical Coherence Tomography in Guiding Percutaneous Coronary Interventions

Bioresorbable Vascular Scaffolds for the Treatment of Chronic Total Occlusions

“…From these limited data, it is difficult to evaluate an impact of intravascular imaging on the clinical outcomes because of small number of cases and short-term follow-up. However, intravascular imaging-guided PCI is associated with better clinical outcomes when compared with angiography alone, [17][18][19][20] and its use and importance in BVS implantation, especially in complex lesions, have been recognized widely. 21 First, intravascular imaging provides morphological information and precise vessel size in complex lesion, which is difficult to evaluate sufficiently with angiography alone.…”

Unexpected Atrial Septal Intramural Hematoma During Coronary Angiography

“…The mechanism of occurrence of extravasation of contrast is not clear. Although we did not perform intravascular ultrasound or optical coherence tomography for the proximal RCA, 15 narrowing, dissection and intimal flap of the proximal RCA on CAG were not observed. Therefore, it is possible that ASH was caused by the perforation of a peripheral microvessel of the atrial artery, not dissection from the ostium to the distal RCA, during coronary angiography using mechanical power injection.…”

Current Use of Intracoronary Imaging in Interventional Practice ― Results of a European Association of Percutaneous Cardiovascular Interventions (EAPCI) and Japanese Association of Cardiovascular Interventions and Therapeutics (CVIT) Clinical Practice Survey ―

“…10 fewer years of experience, which likely accounts, in part, for the less frequent use of IVI in those with less experience compared with more-experienced operators. IVUS and OCT each have inherent strengths and limitations (e.g., higher resolution at the expense of lower penetration for OCT).…”
