  2. Coronary CT angiography - Wikipedia

    en.wikipedia.org/wiki/Coronary_CT_angiography

    Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.

  3. Angiography - Wikipedia

    en.wikipedia.org/wiki/Angiography

    After an angiogram, a sudden shock can cause a little pain at the surgery area, but heart attacks and strokes usually do not occur, as they may in bypass surgery. The risk of complications from angiography can be reduced with a prior CT scan by providing clinicians with more information about number and positioning of the clots in advance. [19 ...

  4. Instantaneous wave-free ratio - Wikipedia

    en.wikipedia.org/wiki/Instantaneous_wave-free_ratio

    The instantaneous wave-free ratio (iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia. iFR is performed during cardiac catheterisation (angiography) using invasive coronary pressure wires which are placed in the coronary ...

  5. Interventional cardiology - Wikipedia

    en.wikipedia.org/wiki/Interventional_cardiology

    Coronary angiography and angioplasty in acute myocardial infarction (left: Right Coronary Artery [RCA] closed, right: successfully dilated) Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases.

  6. Coronary catheterization - Wikipedia

    en.wikipedia.org/wiki/Coronary_catheterization

    Coronary angiography of a critical sub-occlusion of the common trunk of the left coronary artery and the circumflex artery. (See arrows) During coronary catheterization (often referred to as a "cath" or "cardiac cath" by physicians), blood pressures are recorded and fluoroscopy ( X-ray motion picture ) shadow-grams of the blood inside the ...

  7. Computed tomography angiography - Wikipedia

    en.wikipedia.org/.../Computed_tomography_angiography

    Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography—the visualization of arteries and veins—throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of walls ...

  8. Coronary ischemia - Wikipedia

    en.wikipedia.org/wiki/Coronary_ischemia

    Coronary angiography should only be performed if a patient is a willing to undergo a coronary revascularization procedure. [37] During this test the doctor makes a small incision in the patient's groin or arm and inserts a catheter. [35] The catheter has a very small video camera on the end of it so that the doctor can find the arteries. [29]

    ECG, Angiography, Intracoronary optical coherence tomography, Intravascular ultrasound, Coronary CT angiography Spontaneous coronary artery dissection ( SCAD ) is an uncommon but potentially lethal condition in which one of the coronary arteries that supply the heart, spontaneously develops a blood collection, or hematoma , within the artery ...
