  2. Fractional flow reserve - Wikipedia

    en.wikipedia.org/wiki/Fractional_flow_reserve

    Fractional flow reserve (FFR) is a diagnostic technique used in coronary catheterization.FFR measures pressure differences across a coronary artery stenosis (narrowing, usually due to atherosclerosis) to determine the likelihood that the stenosis impedes oxygen delivery to the heart muscle (myocardial ischemia).

  3. Arterial occlusion - Wikipedia

    en.wikipedia.org/wiki/Arterial_occlusion

    Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]

  4. Angiography - Wikipedia

    en.wikipedia.org/wiki/Angiography

    An incision is made in the groin, wrist, or arm, and a catheter is inserted into the artery through it. An X-ray is used to guide the catheter to the area of blockage. A dye is inserted through the catheter to make the places of blockage visible. When the catheter is in position, a thin wire with a balloon is guided to the place of blockage.

  5. Coronary ischemia - Wikipedia

    en.wikipedia.org/wiki/Coronary_ischemia

    This test is very important in finding where the blockages are in the arteries. [29] This test helps determine if an angioplasty or bypass surgery is needed. [36] Coronary angiography should only be performed if a patient is a willing to undergo a coronary revascularization procedure. [37]

  6. Buerger's test - Wikipedia

    en.wikipedia.org/wiki/Buerger's_test

    Buerger's test is performed in an assessment of arterial sufficiency. It is named after Leo Buerger . The vascular angle , which is also called Buerger's angle , is the angle to which the leg has to be raised before it becomes pale, whilst lying down .

  7. Invasive test - Wikipedia

    en.wikipedia.org/wiki/Invasive_Test

    During this procedure, a physician measures the pressure inside the heart, evaluates arteries delivering blood to the heart, and observes how well the heart is pumping. Balloon angioplasty is an invasive test that helps to treat any blockage present in the coronary arteries. A catheter with a small balloon is inserted into the blocked artery ...
