BACKGROUND: Coronary artery anomalies (CAAs) are a relatively rare condition usually diagnosed in vivo by conventional angiography. In the past few years Magnetic resonance coronary angiography (MRCA) has been used to detect CAAs and found to be highly accurate. No data is available regarding the ability of MRCA to detect ...

Cardiovascular magnetic resonance of anomalous coronary arteries is a class I indication. The term anomalous coronary artery encompasses those with an abnormal origin (from the incorrect sinus, too-high or too-low from the correct sinus, or from the pulmonary artery) and/or number of ostia. Their clinical significance results from the increased ...

Anomalous origin of the coronary artery from the contralateral sinus of Valsalva, coursing between the aorta and pulmonary artery, has garnered much attention because of its association with sudden death. Current medical opinion is heavily skewed toward "successful" intervention. However, two key issues have not been critically analyzed: what is ...

Being usually asymptomatic, anomalous coronary arteries (ACAs) are discovered in adulthood using invasive coronary angiography (CA) performed for suspected coronary artery disease. However, if only based on CA, the correct diagnosis is not easily made. We report on the importance of integrated data obtained by using multidetector computed tomography, and ...

Anomalous origin of the left coronary artery from the pulmonary artery generally occurs in isolation. We report an infant diagnosed with double aortic arch and ventricular septal defect who was found to have an anomalous origin of the left coronary artery from the pulmonary artery at surgery. Successful ventricular septal ...

Advances in medicine and technology have increased brachial artery utilization for diagnostic and interventional radiology. Hence, detection and assessment of variations in upper extremity vasculature are important regardless of the low surgical intervention rate in the upper extremity. Anomalies of the upper extremity artery are infrequently reported, and anomalies of ...

BACKGROUND: Anomalous origins of the coronary artery are rare, but may cause myocardial ischemia and sudden death. Thus, their reliable identification is crucial for any imaging method that attempts coronary artery visualization and of those available multislice computed tomography (MSCT), which provides excellent spatial resolution, may be the most promising. ...

Coronary arteriovenous fistulas are among rare anomalies of coronary arteries. Role of X-ray angiography is well established in identification and characterization of these anomalies, however there accurate course and termination is often not defined. We demonstrate role of routine cardiovascular MRI in non-invasively diagnosing and characterizing the course and termination ...

Anomalous coronary arteries are rare and usually identified as an incidental finding during cardiac catheterization. The particular difficulty with cardiac catheterization techniques is not necessarily the presence of the anomalous coronary artery, but its anatomic course. Oftentimes, surgical intervention is necessary once these anomalies are discovered. The identification and anatomic ...

Many surgical procedures for the implantation of anomalous left coronary artery from pulmonary artery have been described. A dual coronary system offers most benefit and is most advantageous for the patient. Two autogenous flaps of the pulmonary trunk and ascending aorta, without mobilizing the coronary artery, were created for use ...

Congenital coronary artery anomalies are rare but can carry a significant risk of myocardial ischemia, myocardial dysfunction, congestive heart failure, and sudden death. This risk seems to be highest during childhood and adolescence; therefore, an understanding of these anomalies is important for the pediatrician and pediatric cardiologist. This article focuses ...
van Ooijen Peter M A - - 2004
Early identification and evaluation of relatively frequent anomalous coronary anatomy is quite relevant because of the occurrence of sudden cardiac death or related symptoms of myocardial ischemia. Selective coronary angiography (CAG) is invasive, expensive and cannot always provide the required information adequately. Recently, non-invasive imaging techniques such as magnetic resonance ...

Anomalous origin of a coronary artery from the pulmonary artery (PA) is an unusual abnormality. These anomalies are often hemodynamically significant and can lead to myocardial ischemia, myocardial infarction, and sudden cardiac death. Anomalous origin of the left coronary artery (LCA) from the pulmonary trunk is known as Bland-White-Garland syndrome ...
