Comparative Appraisal of Intravascular Ultrasound and Optical Coherence Tomography in Invasive Coronary Imaging: 2022 Update

Abstract

Although coronary angiography has been well established as a standard modality for percutaneous coronary intervention guidance, recent developments in intravascular imaging techniques, such as intravascular ultrasound and optical coherence tomography, have become increasingly adopted, enabling direct detailed lesion visualization, including lesions beyond the scope of assessment using exclusively angiography. Intravascular imaging modalities have been reported to potentially improve both short- and long-term percutaneous intervention outcomes. This review aims to provide a comparative summary of recent advancements in research regarding the clinical applications and outcomes of intravascular ultrasound and optical coherence tomography.

Orbital atherectomy for treatment of calcified coronary artery lesions. First experiences in Poland: Short-term outcomes of the Lower-Silesia Orbital Atherectomy Registry (LOAR)

“…Coronary artery calcifications (CAC) have a strong negative impact on the clinical outcomes of percutaneous coronary intervention (PCI). The prevalence of CAC is relatively high and reaches up to 40% when the diagnosis is made based on angiographic assessment and even up to 70% when intravascular ultrasound (IVUS) is used [1,2]. Adequate lesion preparation before drug-eluting stent (DES) implantation is a crucial point of the PCI procedure to achieve satisfying results.…”

Rota-Lithotripsy as a Novel Bail-Out Strategy for Highly Calcified Coronary Lesions in Acute Coronary Syndrome

“…Nevertheless, the procedures have scarcely been introduced in clinical practice and have still managed to obtain bail-out life-saving status in extremely high-risk patients. Moreover, for the same reason, the rate of intravascular guidance has been comparatively low [ 48 ].…”

State-of-art review: intravascular imaging in percutaneous coronary interventions

“…These measurements have been found to correlate reliably with coronary physiological measurements such as instantaneous free-wave ratio (iFR), fractional flow reserve (FFR), and non-invasive stress testing representing ischemic lesions in the right clinical setting [49][50][51] . The studies showed that (Adapted from Baruś et al [45] under Creative Commons License).
