Optical coherence tomography versus intravascular ultrasound to evaluate coronary artery disease and percutaneous coronary intervention
We compared intravascular ultrasound (IVUS) and 2 different generations of optical coherence tomography (OCT)—time-domain OCT (TD-OCT) and frequency-domain OCT (FD-OCT)—for the assessment of coronary disease and percutaneous coronary intervention (PCI) using stents. Background OCT is a promising light-based intravascular imaging modality with higher resolution than IVUS. However, the paucity of data on OCT image quantification has limited its application in clinical practice. Methods A total of 227 matched OCT and IVUS pull backs were studied. One hundred FD-OCT and IVUS pull backs in nonstented (n = 56) and stented (n = 44) vessels were compared. Additionally, 127 matched TD-OCT and ...
