Enhanced IVUS: Advances Allowing Higher Resolution and Integrated Devices

Abstract Purpose of Review Intravascular ultrasound (IVUS) has been in use for nearly 30 years and has greatly assisted in the evaluation and advancement of coronary interventional devices and strategy. With increasing interest in vulnerable plaque, new imaging tools and/or improved IVUS resolution is required. This chapter will describe these enhancements. Recent Findings Optical coherence tomography (OCT) has become catheter based and allows improved definition of vulnerable plaque and fine coronary surface details. Several manufacturers have developed higher-resolution IVUS, achieving a balance between resolution and depth penetration. Additionally, integrated multimodality devices have been developed. The most advanced of these is a combination of near-infrared spectroscopy and IVUS. This catheter allows visualization and quantification of cholesterol-rich lipid plaques co-registered with conventional (and high-resolution) IVUS. Summary Despite widespread demonstration of utility for IVUS in guiding coronary intervention, IVUS continues to be used in only a minority of procedures. With increasing interest in vulnerable plaque, high-resolution IVUS and integrated devices offer new information to assist in the care of complex coronary disease patients.

Conclusions: Clinical or subclinical DVT, an important cause of CVI, may not always be seen on ultrasound, especially after resolution. However, they may have the presence of blood parameters (Factor V and hyperhomocysteinemia) suggestive of DVT; these can be used as proxy markers for the current or previous DVT.

Objective: Breast cancer patients have a higher mortality risk of cardiovascular disease (CVD) than women from the general population. CVD risk may increase significantly in postmenopausal women with early-stage breast cancer. The aim of this study was to evaluate risk factors for CVD in postmenopausal breast cancer survivors. Methods: In this cross-sectional study, 96 postmenopausal breast cancer survivors were compared with 192 postmenopausal women. The main group included women with amenorrhea>12 months, aged ≥45 years, with breast cancer, and without established CVD. The control group fulfilled the same crit...

This study aimed to determine cIMT measurements and its association with cardiovascular risk factors, including fibroblast growth factor-23 (FGF-23) and fetuin-A, in South African children with CKD. MATERIALS AND METHODS: 72 children (5 - 18 years) with CKD; 20 with CKD I, 23 with CKD II - IV, 29 with CKD V (on dialysis) were recruited. Each patient had a clinical examination and blood samples assessed for creatinine, urea, albumin, calcium, phosphorus, parathyroid hormone, alkaline phosphatase, total cholesterol, hemoglobin, C-reactive protein, vitamin D, fetuin-A, and FGF-23. cIMT was measured with high-resolution u...

Effect of Alirocumab on Coronary Atheroma Volume in Japanese Patients With Acute Coronary Syndrome - The ODYSSEY J-IVUS Trial. Circ J. 2019 Aug 20;: Authors: Ako J, Hibi K, Tsujita K, Hiro T, Morino Y, Kozuma K, Shinke T, Otake H, Uno K, Louie MJ, Takagi Y, Miyauchi K Abstract BACKGROUND: In patients with acute coronary syndrome (ACS), alirocumab reduced the risk of recurring ischemic events. ODYSSEY J-IVUS assessed the effect of alirocumab on coronary atheroma volume in Japanese patients recently hospitalized with ACS and hypercholesterolemia, using intravascular ultrasound imaging analysis.Methods...

ández M, Ortiz A Abstract Patients with chronic kidney disease (CKD) are at an increased risk of premature mortality, mainly from cardiovascular causes. The association between CKD on hemodialysis and accelerated atherosclerosis was described>40 years ago. However, more recently, it has been suggested that the increase in atherosclerosis risk is actually observed in early CKD stages, remaining stable thereafter. In this regard, interventions targeting the pathogenesis of atherosclerosis, such as statins, successful in the general population, have failed to benefit patients with very advanced CKD. This ra...

CONCLUSIONS: We found that the levels of ANGPTL-4 increases in obesity in adolescents. However, our results make it difficult to establish a relationship between hepatosteatosis and ANGPTL-4. Targeting ANGPTL-4 may be beneficial for the pathogenesis and associated complications of obesity. PMID: 31419758 [PubMed - as supplied by publisher]

Authors: Ahmadi F, Moukhah S, Hosseini R, Maghari A Abstract Objectives: Ultrasonography is a noninvasive and safe modality for assessing body fat and is routinely performed in developed countries. Although pregnant women with obesity are at risk for many unfavorable outcomes, the relationship between abdominal fat distribution and metabolic syndrome (MS) is evident in some studies. Therefore, it is important to evaluate fat thickness in non-obese women and predict MS using fat thickness measurement. Methods: A total of 132 pregnant women completed anthropometric and demographic questionnaires. All women were s...
