invasive coronary angiography

Invasive coronary angiography is a medical procedure used to examine the blood vessels that supply the heart. A doctor inserts a thin tube, called a catheter, into an artery—usually in the groin or wrist—and guides it to the heart. A special dye then is injected through the catheter, making the coronary arteries visible on X-ray images. This helps doctors identify blockages or narrowing that could affect blood flow. The procedure provides detailed information, enabling accurate diagnosis and guiding treatment options like medication, angioplasty, or surgery.
