    ANGIOPLASTY……???

    ANGIOPLASTY……???

    •A method to
    restores blood flow
    through narrowed
    or blocked coronary
    arteries.
    NEED …….???

    • to relieve a
    blockage of an
    artery caused by
    atherosclerosis, or
    hardening of the
    arteries.
    BEFORE ANGIOPLASTY
    • Diagnostic test is performed called
    cardiac catheterization
    In this procedure:
    procedure
    • A catheter  is threaded through the blood
    vessels leading to the heart
    • A special contrast dye that shows up on x-
    rays is injected into the coronary arteries
    • X-ray images are taken to look for narrowed
    areas in the arteries and determine how
    severe the narrowing's are.
    TYPES
    • BALLOON ANGIOPLASTY

    • LASER ANGIOPLASTY

    • ATHERECTOMY
    BALLOON ANGIOPLASTY
    • An empty and collapsed balloon
    on a guide wire, known as
    a balloon catheter, is passed
    into the narrowed locations and
    then inflated to a fixed size
    using water pressures some 75
    to 500 times normal blood
    pressure(6 to 20 atmospheres).
    The balloon crushes the fatty
    deposits, opening up the blood
    vessel for improved flow, and
    the balloon is then collapsed and
    withdrawn
    CORONARY STENTING

    • A coronary stent is a tube placed in the coronary


    arteries that supply the heart, to keep the arteries
    open in the treatment of coronary heart disease. It is
    used in a procedure called percutaneous coronary
    intervention (PCI)
    LASER ANGIOPLASTY
    • catheter with a laser at its tip
    is used and inserted into an
    artery that opens into
    coronary arteries blocked by
    plaque, a build-up of
    cholesterol, cells and other
    fatty substances in an
    artery's inner lining. Then the
    plastic tube is advanced
    through the artery to the
    blockage in the coronary
    artery, and it emits pulsating
    beams of light from where the
    laser is in position
    CORONARY ATHERECTOMY
    • This procedure is begun similar to angioplasty. But
    instead of a balloon pressing against the fatty
    deposits in the walls of the arteries, special
    instruments are used which cut away the plaque.
    • This technique is proving very useful in treating
    blockages that may be too calcified (hardened) or
    inaccessible for balloon angioplasty

    • TYPES:
    1. DIRECTIONAL
    2. EXTRACTION
    3. ROTATIONAL
    DIRECTIONAL
    • This procedure
    uses a device
    that is a
    combination of a
    balloon and a
    shaving blade.
    The cutting
    device, usually
    located on the
    side, is run back
    and forth and
    shaves the
    deposits away.
    EXTRACTION
     This procedure uses a
    tiny rotating blade
    that works in much the
    same fashion as the
    cutter on a food
    processor to whisk
    away blockages inside
    the artery wall at a
    rate of up to 1,200
    revolutions per minute.
    ROTATIONAL
    • This procedure uses a
    high-speed, diamond-
    tipped drill called
    rotablator to
    penetrate fatty
    deposits and is
    particularly useful on
    hard, calcified plaque.
    • Size is 1.25 to 2.5 mm
    in dia.
    PROCEDURE

    • Shaving, scrubbing and numbing of


    groin
    • Finding the artery
    • Entering needle with wire
    • Introduction of sheath over wire
    • Insertion of catheter
    ….CONTINUED
    • Filming the coronary arteries
    • Viewing coronary arteries from
    different angles
    • Using particular technique relieve
    blockage of narrowed coronary artery
    is done
    PROBLEM’S
    • Re-narrowing of your artery (Restenosis).
    • Blood clots.
    • Bleeding.
    • Heart attack.
    • Coronary artery damage.
    • Abnormal heart rhythms.
    • Stroke.
    • Kidney problems.
    BENEFIT’S
    • Compared to surgical interventions such as
    bypass surgery, balloon angioplasty and stent
    placement are much less invasive and
    relatively low-risk, low-cost procedures.
    • These procedures are performed using local
    anesthesia; no general anesthetic is required
    in the majority of patients.
    • No surgical incision is needed—only a small
    nick in the skin that does not have to be
    stitched closed.
    • You will be able to return to your normal
    activities shortly after the procedure.
    RISKS
    • Inserting the catheter can lead to injury of the
    artery.
    • When angioplasty is performed alone, blockages can
    recur.
    • Heavy bleeding from the catheter insertion site may
    require special medication or a blood transfusion.
    • There is a risk of stroke when angioplasty and/or
    stenting are performed on the carotid artery.
    • Slight risk of infection and allergic reaction
    if contrast material is injected.
    • Contrast material used during these procedures may
    cause renal failure, a decrease in kidney function.
