About

CT (computed tomography) angiography (CTA) is an examination similar to a CAT scan that uses x-rays and a contrast medium (also called dye) to visualize blood flow in arteries and veins throughout the body VISIPAQUE™ will be given through a vein in the arm before having the CTA scan of the heart arteries. The pictures it produces of the heart and its blood vessels will be reviewed and compared to those obtained during the catheter-based coronary angiography to see if the CTA shows the same blockages.

  • Subject must have been referred for an elective coronary angiography for one of several specified conditions.

Exclusion criteria

  • The subject has impaired renal function with a serum creatinine level ≥1.7 mg/dL (150 μmol/L). If the institution's practising guideline(s) regarding the serum creatinine limits for receiving radiologic contrast medium are lower than 1.7 mg/dL (150 μmol/L), the investigator should follow the practising guideline(s) of their institution.
  • Subject has a known allergy to iodinated contrast agent
  • Subject has atrial fibrillation/flutter or any irregular heart rhythm considered to interfere with temporal acquisition of cardiac CT images.
  • The subject's resting heart rate is 66-100 bpm and β-blocker therapy is contraindicated.
  • Use of nitroglycerin is contraindicated.
  • Subject has had a prior CABG procedure.
  • Subject has a metal cardiac stent in place or artificial heart valve(s).
