What is a cardiac angiography examination?

Coronary angiography is a common diagnostic procedure in cardiology. By injecting contrast dye into the patient's vascular system and combining it with X-ray or ultrasound imaging, doctors can clearly observe the structure and function of the heart, aiding in the diagnosis of cardiac abnormalities. It is commonly used to detect the presence and severity of heart conditions such as valvular heart disease, coronary artery disease, and cardiomyopathy. Prior to the procedure, the physician evaluates the patient's overall health, reviews medical history and symptoms, and assesses potential risk factors. During the procedure, the patient receives local anesthesia and is continuously monitored.
