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.

Medical and Biotech [MESH] Definitions
Ultrasonography, Interventional
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.
Needs Assessment
Systematic identification of a population's needs or the assessment of individuals to determine the proper level of services needed.
Outcome And Process Assessment (health Care)
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.
Ultrasound, High-intensity Focused, Transrectal
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).
Klatskin's Tumor
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. (From Holland et al., Cancer Medicine, 3d ed, p1457)
