OBJECTIVES: The authors sought to explore the comparative clinical efficacy of different imaging modalities for guiding percutaneous coronary interventions (PCI). BACKGROUND: Coronary angiography (CA) is the standard imaging modality for intraprocedural guidance of PCI. Intracoronary imaging techniques, including intravascular ultrasound (IVUS) and optical coherence tomography (OCT), can overcome some limitations of CA. METHODS: Comprehensive hierarchical Bayesian network meta-analysis of randomized clinical trials and adjusted observational studies comparing clinical outcomes of PCI with stent implantation guided by CA, IVUS, or OCT...

Although the hybrid chronic total occlusion (CTO) algorithm had many excellent recommendations, there has been infrequent adoption in the Asia Pacific region. The Asia Pacific CTO club propose an algorithm for case selection based on the Japan-CTO score and a new CTO algorithm, which is applicable globally. This algorithm allows for differing skill sets and equipment availability and contains practical teaching for CTO percutaneous coronary intervention. Similar to the hybrid algorithm there are 3 main questions that determine whether the primary approach is antegrade or retrograde: 1) is there proximal cap ambiguity; 2) is the distal vessel of poor quality; and 3) are there interventional collaterals present...

BACKGROUND: Ultrasound is rarely used for guiding lumbosacral epidural steroid injections due to its technical limitations. For example, sonographic imaging lacks the ability to confirm epidural spread and identify vascular uptake. The perceived risk that these limitations pose to human subjects has precluded any large scale clinical trials to date. OBJECTIVE: To compare the accuracy of ultrasound versus fluoroscopic guidance for first sacral transforaminal epidural injections DESIGN: Cadaveric comparative study using dichotomous outcomes...

OBJECTIVE: Previous evidence suggested that intravascular ultrasound (IVUS) guidance could improve outcomes after drug-eluting stents (DES) placement, largely driven by data from observational studies. We, therefore, performed a meta-analysis and trial sequential analysis of randomized controlled trials to overcome this limitation. RESULTS: The retrieval process yielded 7 RCTs with 3,192 patients. Compared to the angiography guidance, IVUS-guided DES implantation was associated with a significant reduction in the major adverse cardiac events (MACE) (OR 0...

The aim of this study was to assess the efficacy of a biolimus A9-eluting stent in patients with a right coronary artery (RCA) ostial lesion. Ostial lesions of the RCA have been a limitation of percutaneous coronary intervention even in the drug-eluting stent (DES) era. However, clinical outcomes after the deployment of a second generation DES to an RCA ostial lesion with intravascular ultrasound (IVUS) guidance have not been fully elucidated. From September 2011 to March 2013, 74 patients were enrolled in 17 centers from Japan...

BACKGROUND: Increasing coronary lesion calcification is thought to be associated with adverse percutaneous coronary intervention (PCI) and clinical outcomes. We investigated the effects of calcium burden on culprit lesion morphology and clinical events after intravascular ultrasound (IVUS)-guided PCI in the ADAPT-DES study. METHODS: ADAPT-DES was a prospective, multicenter registry of 8582 consecutive patients undergoing successful PCI using DES. A pre-specified virtual histology (VH)-IVUS substudy of 638 culprit lesions (638 patients) had both pre- and post-PCI VH-IVUS...

Contrast-induced nephropathy (CIN) is a serious complication in patients undergoing percutaneous coronary intervention (PCI), and is associated with higher morbidity and mortality. The limiting volume of contrast medium is safest and most reliable strategy for CIN prevention. Intravascular ultrasound (IVUS) serves as an attractive alternative imaging tool to angiography in many steps during PCI, thereby reducing the use of contrast agents. Here, we reported a case of successfully treated unprotected left main bifurcation lesion with heavily calcified and diffuse lesion under the IVUS-guided PCI using low volumes of contrast dye of total 12 cc in an elderly patient...

The difference in the intraluminal intensity of blood speckle (IBS) on integrated backscatter-intravascular ultrasound (IB-IVUS) across a coronary artery stenosis (i.e., ΔIBS) has previously shown a negative correlation with fractional flow reserve, reflecting an impaired coronary blood flow. Periprocedural myocardial injury (PMI) after coronary stenting has also been associated with coronary circulatory dysfunction. The aim of this study was to investigate the relation between ΔIBS after coronary stenting and PMI...

PURPOSE: To investigate the 1-year outcomes of transvenous intravascular ultrasound (IVUS)-guided endovascular therapy (EVT) for chronic total occlusion (CTO) of the lower extremity arteries. METHODS: Transvenous IVUS-guided EVT was performed in 44 patients (50 limbs) with CTO of the femoropopliteal arteries or tibioperoneal trunk. Treatment involved crossing a guidewire through the CTO under the guidance of both fluoroscopic and IVUS imaging, along with insertion of the IVUS catheter into a vein parallel to the target artery...

Cardiovascular disease remains the most common cause of death worldwide. Enormous progress in the technology and applicability of percutaneous techniques to treat obstructive coronary heart disease has been made, and the number of percutaneous coronary interventions (PCI) is increasing. Coronary bifurcations are involved in a substantial number of PCIs and despite recent advances, bifurcation PCI remains a challenge in terms of immediate success and long-term outcome. Angiography has a limited capacity for showing important features of the 3 dimensional coronary vessel anatomy, position of stent struts and exact wire positions and is therefore suboptimal for guiding bifurcation PCI...

Teruyoshi Kume, Shiro Uemura
Optical coherence tomography (OCT) is an intra-coronary diagnostic technique that provides detailed imagings of blood vessels in the current cardiac catheterization laboratory. The higher resolution of OCT often provides superior delineation of each structure compared with intravascular ultrasound (IVUS), and it can reliably visualize the microstructure of normal and diseased arteries. The capabilities of OCT are well suited for the identification of calcified plaque and neointima formation after stent implantation...

PURPOSE OF REVIEW: Enthusiasm for regional anesthesia has been driven by multimodal benefits to patient outcomes. Despite widespread awareness and improved techniques (including the increasing use of ultrasound guidance for block placement), intravascular sequestration and the attendant risk of local anesthetic systemic toxicity (LAST) remains. Intravenous lipid emulsion (ILE) for the treatment of LAST has been endorsed by anesthetic regulatory societies on the basis of animal study and human case report data...

Thoracic aortic pseudoaneurysms are a recognized complication following aortic arch replacement. The established first line treatment is surgical repair; however, this may not be feasible in all patients. Percutaneous treatment of ascending thoracic pseudoaneurysms has been described as an alternative for nonsurgical candidates. Utilization of multimodality imaging can prove invaluable in minimizing the risk of potentially fatal intra-procedural complications. We present a case of successful embolization using computer tomography-guided direct percutaneous puncture of the pseudoaneurysm, with concomitant endovascular treatment under fluoroscopic and intravascular ultrasound guidance in a patient with challenging vascular anatomy...
