Cardiac catheterization is a broader procedure, often including coronary angiography. 1It involves inserting a catheter into the heart for diagnosis or treatment. Coronary angiography specifically visualizes coronary arteries using dye and X-rays to detect blockages. Catheterization can also facilitate interventions like angioplasty, while angiography is primarily diagnostic. Both are crucial for heart health, with catheterization offering therapeutic options. https://amcarehospital.com/cardiac-catheterization-vs-coronary-angiography-a-guide-to-heart-health-procedures/
