Bifurcation lesion morphology and intravascular ultrasound assessment.

Summary of "Bifurcation lesion morphology and intravascular ultrasound assessment."

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.

Role of intravascular ultrasound (IVUS) in determining the therapeutic strategy for the patients with intermediate coronary lesions.

Background: Coronarography presents some limits in assessing intermediate stenosis. Intravascular ultrasound provides tridimensional measurements of the artery, with more reliable data guiding revascu...

Currently available methodologies for the processing of intravascular ultrasound and optical coherence tomography images.

Optical coherence tomography and intravascular ultrasound are the most widely used methodologies in clinical practice as they provide high resolution cross-sectional images that allow comprehensive vi...

Current status of intravascular ultrasound in interventional cardiology.

Although intravascular ultrasound has been used for decades, its common application in catheterization centres during coronary interventions is very rare and merely reaches few percents. The reason is...

Shape-Based Approach for Coronary Calcium Lesion Volume Measurement on Intravascular Ultrasound Imaging and Its Association With Carotid Intima-Media Thickness.

Coronary calcification plays an important role in diagnostic classification of lesion subsets. According to histopathologic studies, vulnerable atherosclerotic plaque contains calcified deposits, and ...

Optical coherence tomography of coronary arteries - a novel intravascular imaging modality.

Optical coherence tomography (OCT) is the latest intravascular imaging modality for the investigation of coronary arteries. It can be used in patients with stable coronary artery disease as well as in...

Medical and Biotech [MESH] Definitions

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.
