reported two cases the first patient was a 34 year old woman with supraventricular tachycardia and second was a 54 year old man with atypical chest pain. Neither of the patients had notable atherosclerotic coronary artery disease in the dual left anterior descending system using the ECG gated 64 MDCT coronary angiography.
Background. Congenital anomalies in coronary artery origin are observed in 0.2–1.2 of the population1 and detection of these abnormalities by coronary angiography CAG is rare at about 1–5 .2 Some coronary artery origin anomalies are an important cause of sudden death during exercise in young athletes. However less than half of the cases show symptoms such
Oct 02 2015 The recent development of ECG gated multi detector row computed tomography MDCT coronary angiography allows accurate and noninvasive depiction of coronary artery anomalies. Methods This retrospective study included 2572 patients who underwent coronary 64 slice MDCT coronary angiography from January 2008 to March 2012.
Jul 23 2021 Overview. A heart scan coronary calcium scan provides pictures of your heart s arteries. Doctors may use this test to look for calcium deposits in the coronary arteries that can narrow your arteries and increase your heart attack risk. The image on the left shows where the heart is located in the body A and the middle image shows the area

Feb 01 2022 An angioplasty may be done to open an artery blocked by plaque. A tube with a balloon on the end is put into the blocked artery. When the tube is in the artery the balloon is inflated. As the balloon inflates it presses the plaque against the artery wall to open the artery. A stent may be placed in your artery to keep it open.
selective coronary angiography producing increases in lu minal areas of between 20 and 40 in normal arteries and 5 and 10 in diseased coronary artery segments 9 10 . Although this technique may allow for improved identifica tion of stenosed coronary artery segments it harbors the potential to overestimate the degree of stenosis.

The vasodilatory effect of nitroglycerin on coronary vessels has been studied extensively in selective coronary angiography producing increases in luminal areas of between 20 and 40 in normal arteries and 5 and 10 in diseased coronary artery segments 9 10 . Although this technique may allow for improved identification of stenosed coronary
Electrocardiogram ECG gated CTA allowed better identification of anomalous coronary arteries than non gated CTA. In all dogs the right coronary artery had a smaller diameter than the left and the left coronary artery or its branch had a prepulmonic course.
Results and Conclusion Coronary artery anomalies can be anatomically subdivided into anomalies of origin course and termination. The method of choice for anatomical imaging is ECG triggered or gated multislice CT MSCT that provides high spatial resolution and the capability of multiplanar reconstructions.

When the coronary arteries narrow to the point that blood flow to the heart muscle is limited coronary artery disease collateral vessels may enlarge and become active. This allows blood to flow around the blocked artery to another artery nearby or to the same artery past the blockage protecting the heart tissue from injury.

A new test is available to diagnose coronary artery disease.In the past noninvasive functional tests of the heart were used such as treadmill tests and nuclear studies to indirectly assess if there were blockages in the coronary arteries. The only way to directly look at the coronary arteries was via a cardiac catheterization and coronary angiogram.
Feb 04 2022 Coronary angiography is often done along with cardiac catheterization. This is a procedure that measures pressures in the heart chambers. Before the test starts you will be given a mild sedative to help you relax. An area of your body the arm or groin is cleaned and numbed with a local numbing medicine anesthetic .
Jan 22 2009 Non ECG gated cardiac CT in which the coronary artery is not of primary diagnostic concern is frequently able to visualize the origin and proximal course of coronary arteries and may be helpful in detecting coronary artery
Advanced cardiac imaging using cardiac magnetic resonance imaging MRI and multidetector computed tomography CT is increasingly used in the work up of athletes with suspected abnormalities on screening. Both imaging modalities produce highly accurate and reproducible structural and functional cardiac information. Cardiac MRI has the advantage of imaging
Feb 27 2015 Coronary artery anomaly is defined as an anatomical variation observed in < 1 of the general population. Two classification systems for coronary artery anomalies are commonly used 28 29 . One is according to the location of the anomalies including origin course and termination while the other is according to hemodynamic significance of
Jun 01 2015 Coronary angiograms of a 51 year old woman in A anteroposterior and B left anterior oblique views show that the entire coronary system arises from a single ostium in the right sinus of Valsalva.The right coronary artery RCA splits from a common trunk CT and continues in normal position.
Anomalous Coronary Artery. An anomalous coronary artery wasn’t formed correctly in the womb. This rare problem means your coronary artery is in the wrong spot or it started in the wrong spot. This can cause problems with how your blood circulates through your heart. When your heart muscle doesn’t get the oxygen it needs tissues can die.

Coronary artery disease CAD is a condition in which plaque builds up inside the coronary arteries. These arteries supply your heart muscle with oxygen rich blood. Plaque is made up of fat cholesterol calcium and other substances found in the blood. When plaque builds up in the arteries the condition is called atherosclerosis.
Coronary magnetic resonance angiography has already been demonstrated to be of clinical value for the assessment of anomalous coronary artery disease and it is
Single coronary artery is a coincidental finding during coronary angiography or at autopsy. Although it is a rare condition and most of time has an asymptomatic clinic prognosis varies. We would like to report a case about percutaneous coronary intervention in a patient who has anomalous single coronary artery arising from right sinus valsalva.
Coronary CT angiography 128 multidetector CT retrospective ECG gated with restrictive dose modulation 70 kVs 1.2 mSv revealed the origin of the LCA from the pulmonary artery trunk/root junction immediately above the sinus of Valsalva and was consistent with remaining echocardiography findings figure 1 .
