Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage"), is a surgical procedure to treat coronary artery disease (CAD), the buildup of plaques in the arteries of the heart.
Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
This procedure allows for better imaging of the aorta, pulmonary artery, heart valves, atria, atrial septum, left atrial appendage, and coronary arteries. It can also be used during cardiac surgery to monitor the patient and assess the success of surgical interventions. [5]
One of the most common angiograms performed is to visualize the coronary arteries. A long, thin, flexible tube called a catheter is used to administer the X-ray contrast agent at the desired area to be visualized. The catheter is threaded into an artery in the forearm, and the tip is advanced through the arterial system into the major coronary ...
CTA is the test of choice when assessing aneurysm before and after endovascular stenting due to the ability to detect calcium within the wall. [3] Another positive of CTA in abdominal aortic aneurysm assessment is that it allows for better estimation of blood vessel dilation and can better detect blood clots compared to standard angiography.

A variety of blood tests are available for analyzing cholesterol transport behavior, HDL, LDL, triglycerides, lipoprotein little a, homocysteine, C-reactive protein, blood sugar control: fasting, after eating or averages using glycated albumen or hemoglobin, myoglobin, creatine kinase, troponin, brain-type natriuretic peptide, etc. to assess the evolution of coronary artery disease and ...
Coronary angiography of a critical sub-occlusion of the common trunk of the left coronary artery and the circumflex artery. (See arrows) During coronary catheterization (often referred to as a "cath" or "cardiac cath" by physicians), blood pressures are recorded and fluoroscopy (X-ray motion picture) shadow-grams of the blood inside the ...
The aortic valve is one of the two semilunar valves of the heart with three cusps. It separates the heart from the aorta. Each cusp is attached to the aortic wall creating a sinus called an aortic sinus. The origins of the two coronary arteries are sited in two aortic sinuses.
