Aneurysm

aneurysmsaneurismruptured aneurysm
Specifically, coronary catheterization is a visually interpreted test performed to recognize occlusion, stenosis, restenosis, thrombosis or aneurysmal enlargement of the coronary artery lumens; heart chamber size; heart muscle contraction performance; and some aspects of heart valve function.
Pseudoaneurysms can be caused by trauma that punctures the artery, such as knife and bullet wounds, as a result of percutaneous surgical procedures such as coronary angiography or arterial grafting, or use of an artery for injection.

Myocardial infarction

heart attackheart attacksacute myocardial infarction
Very advanced luminal occlusion usually produces a heart attack. Since the late 1970s, building on the pioneering work of Charles Dotter in 1964 and especially Andreas Gruentzig starting in 1977, coronary catheterization has been extended to therapeutic uses: (a) the performance of less invasive physical treatment for angina and some of the complications of severe atherosclerosis, (b) treating heart attacks before complete damage has occurred and (c) research for better understanding of the pathology of coronary artery disease and atherosclerosis.
A number of tests are useful to help with diagnosis, including electrocardiograms (ECGs), blood tests, and coronary angiography.

Minimally invasive procedures

A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter.
Other examples of minimally invasive procedures include the use of hypodermic injection, and air-pressure injection, subdermal implants, refractive surgery, percutaneous surgery, cryosurgery, microsurgery, keyhole surgery, endovascular surgery using interventional radiology (such as angioplasty), coronary catheterization, permanent placement of spinal and brain electrodes, stereotactic surgery, the Nuss procedure, radioactivity-based medical imaging methods, such as gamma camera, positron emission tomography and SPECT (single photon emission tomography).

In 1960 F. Mason Sones, a pediatric cardiologist at the Cleveland Clinic, accidentally injected radiocontrast in a coronary artery instead of the left ventricle.
F. Mason Sones, Jr. (October 28, 1918 – August 28, 1985) was an American physician whose pioneering work in cardiac catheterization was instrumental in the development of both coronary artery bypass surgery and interventional cardiology.

A number of tests may help with diagnoses including: electrocardiogram, cardiac stress testing, coronary computed tomographic angiography, and coronary angiogram, among others.

Cardiology diagnostic tests and procedures

Coronary catheterization is one of the several cardiology diagnostic tests and procedures.
Cardiac imaging techniques include coronary catheterization, echocardiogram, intravascular ultrasound, and the coronary calcium scan.

Angina

Since the late 1970s, building on the pioneering work of Charles Dotter in 1964 and especially Andreas Gruentzig starting in 1977, coronary catheterization has been extended to therapeutic uses: (a) the performance of less invasive physical treatment for angina and some of the complications of severe atherosclerosis, (b) treating heart attacks before complete damage has occurred and (c) research for better understanding of the pathology of coronary artery disease and atherosclerosis. Coronary artery luminal narrowing reduces the flow reserve for oxygenated blood to the heart, typically producing intermittent angina.
In patients in whom such noninvasive testing is diagnostic, a coronary angiogram is typically performed to identify the nature of the coronary lesion, and whether this would be a candidate for angioplasty, coronary artery bypass graft (CABG), treatment only with medication, or other treatments.

Atheroma

The relevant problems that the test deals with most commonly occur as a result of advanced atherosclerosis – atheroma activity within the wall of the coronary arteries.

Variant angina

Workup of suspected Prinzmetal Angina (coronary vasospasm)
However, the gold standard for diagnosing variant angina is to visualize coronary arteries by angiography before and after injection of a provocative agent such as ergonovine, methylergonovine or acetylcholine to precipitate an attack of vasospasm.

Fractional flow reserve

Fractional flow reserve
Fractional flow reserve (FFR) is a technique used in coronary catheterization to measure pressure differences across a coronary artery stenosis (narrowing, usually due to atherosclerosis) to determine the likelihood that the stenosis impedes oxygen delivery to the heart muscle (myocardial ischemia).
