What to Expect During Coronary Angiography
Preparation, catheter access, imaging, possible intervention and recovery after coronary angiography.
Physician-reviewed patient informationOverview
Coronary angiography uses a thin catheter, usually through the wrist or groin artery, and contrast to define the coronary anatomy. Kidney function, allergy history and current medicines are reviewed beforehand.
The angiogram is diagnostic. If a significant narrowing is found, balloon angioplasty or stenting may be considered during the same session or planned separately, depending on anatomy, symptoms and clinical risk.
After the procedure, access-site care, hydration advice and medicine instructions must follow the treating hospital's plan. Increasing swelling, persistent bleeding, chest pain or severe breathlessness requires prompt medical attention.
