a radiographic process in which the aorta and its branches are injected with any of various contrast media for visualization. aortographic, adj. a·or·tog·ra·phy. 1. A radiographic study of the aorta and its branches by injection of a radiopaque contrast medium and a rapid sequence of images to demonstrate blood flow.
Aortography is being replaced by newer imaging modalities because of risks associated with invasiveness and adverse reactions to intravenous contrast agents.
Aortography has largely been replaced by the diagnostic tools of MRI, CT, and transesophageal echocardiography (TEE) all of which have high sensitivities. TEE is favored in emergency situations, as it is relatively non-invasive and a rapid procedure (more so than MRI, which can takes hours).

Percutaneous Coronary Intervention (PCI, formerly known as angioplasty with stent) is a non-surgical procedure that uses a catheter (a thin flexible tube) to place a small structure called a stent to open up blood vessels in the heart that have been narrowed by plaque buildup, a condition known as atherosclerosis.
Phlebosclerosis refers to the thickening and hardening of the venous wall.
Tetralogy of Fallot is a combination of four congenital heart defects. The four defects are a ventricular septal defect (VSD), pulmonary stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy). They usually result in a lack of oxygen-rich blood reaching the body.
Peripheral Component Interconnect, or PCI, is the most common way to attach add-on controller cards and other devices to a computer motherboard. This type of connector originated in the early 1990s, and is still in use today. Presently, there are three main PCI motherboard connectors (usually referred to as "slots".)
The PCI Data Security Standard PCI DSS is the global data security standard adopted by the payment card brands for all entities that process, store or transmit cardholder data and/or sensitive authentication data. It consists of steps that mirror security best practices.

Aortography involves placement of a catheter in the aorta and injection of contrast material while taking X-rays of the aorta. The procedure is known as an aortogram. The diagnosis of aortic dissection can be made by visualization of the intimal flap and flow of contrast material in both the true lumen and the false lumen.
The aortogram was previously considered the gold standard test for the diagnosis of aortic dissection, with a sensitivity of up to 80% and a specificity of about 94%. It is especially poor in the diagnosis of cases where the dissection is due to hemorrhage within the media without any initiating intimal tear.
The advantage of the aortogram in the diagnosis of aortic dissection is that it can delineate the extent of involvement of the aorta and branch vessels and can diagnose aortic insufficiency. The disadvantages of the aortogram are that it is an invasive procedure and it requires the use of iodinated contrast material.
TEE is favored in emergency situations, as it is relatively non-invasive and a rapid procedure (more so than MRI, which can takes hours).

For aortic regurgitation, an aortogram is performed in the ascending thoracic aorta above the aortic valve, and the amount of contrast that regurgitates into the left ventricle (LV) is noted. For mitral regurgitation, a left ventriculogram is performed, and the amount of contrast that regurgitates into the left atrium (LA) is noted.
