Heart造影怎么做的

Cardiac angiography is generally divided into two types: coronary angiography and ventriculography. The specific procedures are as follows: 1. Coronary angiography: The doctor inserts a catheter into the patient's arm or leg, advances it into the coronary arteries, and injects a special contrast agent to visualize the coronary arteries. During this procedure, the doctor uses X-ray imaging to monitor the flow of the contrast agent through the coronary arteries, thereby identifying any narrowing or blockages. 2. Ventriculography: The doctor inserts a catheter into the patient's arm or leg, guides it into the heart, and injects contrast agent to visualize the heart's chambers. Throughout the process, X-ray imaging is used to observe the heart's contraction and relaxation, allowing assessment of cardiac function. During cardiac angiography, patients may experience some temporary discomfort, such as mild chest tightness, palpitations, or nausea, but these sensations are usually transient.
