Introduction to Cardiovascular Angiography

Cardiovascular angiography is a technique to visualize the cardiovascular system by injecting a contrast agent. In order to identify any heart chambers, large blood vessels or coronary vessels in a cardiac catheter, this radiography technique is required.

It is to quickly inject a transparent contrast agent containing organic compounds under X-ray irradiation into the blood stream, so that the heart and large blood vessel cavity can be developed under X-ray irradiation. The imaging process of the vascular cavity is photographed. From the imaging results, you can see the blood flow sequence containing the contrast agent and the filling of the large blood vessels of the heart, so as to understand the physiological and anatomical changes of the heart and large blood vessels. It is a very valuable method for diagnosing cardiovascular disease.

The contrast agent is directly and quickly injected into the selected heart cavity or large blood vessel with the help of a cardiac catheter, so that the highest concentration can be quickly reached there, and a good visualization can be obtained, which can clearly show the lesions in this part. It has become one of the commonly used diagnostic methods for cardiovascular diseases, especially for the preoperative diagnosis of complex cardiovascular malformations or coronary artery bypass grafts.
