Abstract

Cumulative evidence from histology-based studies demonstrate that the currently available intravascular imaging techniques have fundamental limitations that do not allow complete and detailed evaluation of plaque morphology and pathobiology, limiting the ability to accurately identify high-risk plaques. To overcome these drawbacks, new efforts are developing for data fusion methodologies and the design of hybrid, dual-probe catheters to enable accurate assessment of plaque characteristics, and reliable identification of high-risk lesions. Today several dual-probe catheters have been introduced including combined near infrared spectroscopy-intravascular ultrasound (NIRS-IVUS), that is already commercially available, IVUS-optical coherence tomography (OCT), the OCT-NIRS, the OCT-near infrared fluorescence (NIRF) molecular imaging, IVUS-NIRF, IVUS intravascular photoacoustic imaging and combined fluorescence lifetime-IVUS imaging. These multimodal approaches appear able to overcome limitations of standalone imaging and provide comprehensive visualization of plaque composition and plaque biology. The aim of this review article is to summarize the advances in hybrid intravascular imaging, discuss the technical challenges that should be addressed in order to have a use in the clinical arena, and present the evidence from their first applications aiming to highlight their potential value in the study of atherosclerosis.

32. Emerging Hybrid Intracoronary Imaging Technologies and Their Applications in Clinical Practice and Research.

Abstract

Intravascular ultrasound and optical coherence tomography are used with increasing frequency for the care of coronary patients and in research studies. These imaging tools can identify culprit lesions in acute coronary syndromes, assess coronary stenosis severity, guide percutaneous coronary intervention (PCI), and detect vulnerable plaques and patients. However, they have significant limitations that have stimulated the development of multimodality intracoronary imaging catheters, which provide improvements in assessing vessel wall pathology and guiding PCI. Prototypes combining 2 or even 3 imaging probes with complementary attributes have been developed, and several multimodality systems have already been used in patients, with near-infrared spectroscopy intravascular ultrasound–based studies showing promising results for the identification of high-risk plaques. Moreover, postmortem histology studies have documented that hybrid imaging catheters can enable more accurate characterization of plaque morphology than standalone imaging. This review describes the evolution in the field of hybrid intracoronary imaging; presents the available multimodality catheters; and discusses their potential role in PCI guidance, vulnerable plaque detection, and the assessment of endovascular devices and emerging pharmacotherapies targeting atherosclerosis. [Display omitted] • Novel hybrid intracoronary devices overcome limitations of standalone imaging for plaque characterization and PCI guidance. • The use of multimodality imaging may improve outcomes following interventional treatment in challenging clinical scenarios. • Large-scale studies are needed to determine the role of hybrid intracoronary imaging in guiding revascularization, vulnerable plaque detection, and cardiovascular risk stratification.

Abstract

Objectives: Use of intracoronary imaging (ICI) in cases of stent thrombosis (ST) is recommended and tailored treatment appears reasonable. Nevertheless, data supporting such a strategy are lacking. The aim of this study was to evaluate the clinical impact of ICI in the management of ST. Methods: The unadjusted study population was consecutive patients with definite ST presenting in a single tertiary cardiac centre and undergoing percutaneous coronary intervention (PCI). The presumed major mechanism of ST was assigned according to the real-time ICI interpretation by the PCI operator. Propensity score matching was performed with regard to ICI use to form the adjusted population and Kaplan–Meier analysis was applied to compare survival free of cardiac death (CD) or target lesion revascularization (TLR). Results: The unadjusted population included 130 ST patients, with the majority presenting with ST-elevation myocardial infarction (STEMI) (88%) and very late ST (86%). ICI was performed in 45 patients, of whom optical coherence tomography (OCT) was performed in 30 cases. When the individual ST mechanisms were viewed as groups, there was an interaction observed between type of treatment (stent vs. non-stent) and ST mechanism, with non-stent treatment being more prevalent in cases of underexpansion, malapposition, in-stent restenosis and mechanism uncertainty. After application of matching, two groups of 30 patients were formed. ICI-guided management resulted in better survival free of CD–TLR at 2 years (93% vs. 73%, p = 0.037). Conclusions: Intracoronary imaging guidance during PCI for ST had a direct impact on management (stent vs. non-stent) and resulted in a lower event rate at mid-term follow-up when propensity matched analysis was applied.

44. The effect of CTCA guided selective invasive graft assessment on coronary angiographic parameters and outcomes: Insights from the BYPASS-CTCA trial.

Abstract

Computed tomography cardiac angiography (CTCA) is recommended for the evaluation of patients with prior coronary artery bypass graft (CABG) surgery. The BYPASS-CTCA study demonstrated that CTCA prior to invasive coronary angiography (ICA) in CABG patients leads to significant reductions in procedure time and contrast-induced nephropathy (CIN), alongside improved patient satisfaction. However, whether CTCA information was used to facilitate selective graft cannulation at ICA was not protocol mandated. In this post-hoc analysis we investigated the influence of CTCA facilitated selective graft assessment on angiographic parameters and study endpoints. BYPASS-CTCA was a randomized controlled trial in which patients with previous CABG referred for ICA were randomized to undergo CTCA prior to ICA, or ICA alone. In this post-hoc analysis we assessed the impact of selective ICA (grafts not invasively cannulated based on the CTCA result) following CTCA versus non-selective ICA (imaging all grafts irrespective of CTCA findings). The primary endpoints were ICA procedural duration, incidence of CIN, and patient satisfaction post-ICA. Secondary endpoints included the incidence of procedural complications and 1-year major adverse cardiac events. In the CTCA cohort (n ​= ​343), 214 (62.4%) patients had selective coronary angiography performed, whereas 129 (37.6%) patients had non-selective ICA. Procedure times were significantly reduced in the selective CTCA ​+ ​ICA group compared to the non-selective CTCA ​+ ​ICA group (−5.82min, 95% CI -7.99 to −3.65, p ​< ​0.001) along with reduction of CIN (1.5% vs 5.8%, OR 0.26, 95% CI 0.10 to 0.98). No difference was seen in patient satisfaction with the ICA, however procedural complications (0.9% vs 4.7%, OR 0.21, 95% CI 0.09–0.87) and 1-year major adverse cardiac events (13.1% vs 20.9%, HR 0.55, 95% CI 0.32–0.96) were significantly lower in the selective group. In patients with prior CABG, CTCA guided selective angiographic assessment of bypass grafts is associated with improved procedural parameters, lower complication rates and better 12-month outcomes. Taken in addition to the main findings of the BYPASS-CTCA trial, these results suggest a synergistic approach between CTCA and ICA should be considered in this patient group.
