Angiocardiography is a technique for radiographic examination of the heart chambers and thoracic veins and arteries. A liquid radiocontrast agent, typically containing iodine, is injected into the bloodstream, then the tissues are examined using X-rays.[1] To avoid dilution, the radiopaque material is typically introduced with a catheter, a process known as selective angiocardiography. The X-ray image is normally captured on high speed serial media that allows the motion to be observed, such as 35mm film.[2] The process requires fasting before the test, with a sedative and an antihistamine being administered before the test.[3]

Angiocardiography can be used to detect and diagnose congenital defects in the heart and adjacent vessels.[3] The use of angiocardiography has declined with the introduction of echocardiography. However, angiocardiography is still in use for selected cases as it provides a higher level of anatomical detail than echocardiography.[4][5]
