This repot reviews the angiographic and intravascular (IVUS) assessment of coronary bifurcation lesions. Overall, bifurcation lesion anatomy and morphology is critical for technical decision making, and a key factor for successful bifurcation PCI. Optimal viewing is essential for proper angiographic assessment, especially for evaluation of the degree of SB involvement. Current classifications based on the presence or absence of significant angiographic stenosis within the three segments of the bifurcation anatomy may not provide sufficient anatomic and morphologic information to guide technical decision making. Dedicated 2D bifurcation quantitative coronary angiography with segmental analysis of the bifurcation provides greater accuracy for quantification of the degree of stenosis in the PV and especially the SB ostium. IVUS assessment at preprocedure provides valuable information regarding vessel size, and plaque morphology and distribution (particularly in relation to the SB ostium) that may help select treatment strategy. At postprocedure, IVUS imaging evaluates stent apposition within the stented segment(s) and the appropriateness of stent expansion particularly at the SB ostium, what may impact long-term outcomes.

Our study evaluated the relationship between platelet reactivity and plaque morphology using grayscale and radiofrequency intravascular ultrasound (IVUS) virtual histology (VH).
Bifurcation lesions are a therapeutic challenge in the interventional treatment of coronary artery disease. Thus, consideration of anatomical aspects and selection of the most appropriate strategy for...
The DEFINITION (Impact of the complexity of bifurcation lesions treated with drug-eluting stents) study has provided a novel classification to evaluate the complexity of coronary bifurcation lesion ac...
The aim of this study was to analyze the difference in neointima pattern assessed by intravascular ultrasound (IVUS) between two dedicated bifurcation stents, BiOSS® Expert and BiOSS® LIM at 12-mont...
The primary objective is to determine whether IVUS- (vs. OCT-) guided BVS implantation is non-inferior to achieve a large in-scaffold minimal lumen area (primary endpoint) measured by OCT ...
The COBIS registry is multi-center, real-world registry of drug-eluting stenting in coronary bifurcation lesions in South Korea. The aim of the study was to find out the current status of...
To diagnose hepatocellular carcinoma (HCC) and to determine the extent of the disease, a triphasic CT scan or a magnetic resonance imaging are required. The characterization of hepatic nod...
1. Stains have demonstrated consistent benefits to reduce cardiovascular events in several primary and secondary prevention trials. The suppression of plaque progression or regre...
The purpose of this study is to evaluate the effect of combination therapy with cilostazol and probucol on plaque volume and composition change in comparison with cilostazol alone by seria...
The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
Systematic identification of a population's needs or the assessment of individuals to determine the proper level of services needed.
Evaluation procedures that focus on both the outcome or status (OUTCOMES ASSESSMENT) of the patient at the end of an episode of care - presence of symptoms, level of activity, and mortality; and the process (ASSESSMENT, PROCESS) - what is done for the patient diagnostically and therapeutically.
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Adenocarcinoma of the common hepatic duct bifurcation. These tumors are generally small, sharply localized, and seldom metastasizing. G. Klatskin's original review of 13 cases was published in 1965. Once thought to be relatively uncommon, tumors of the bifurcation of the bile duct now appear to comprise more than one-half of all bile duct cancers.

Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
