Congenital anomalies of the coronary arteries can be divided into two broad categories: those that alter myocardial perfusion and those that do not. In coronary anomalies not altering myocardial perfusion, the coronary arteries originate from the aorta, but their origins are in unusual positions. Although myocardial perfusion is normal, the angiographer may have trouble locating them. Patients ...

Congenital coronary artery anomalies are one of the causes of myocardial ischemia and sudden death in the young, mainly during sports. Origin of the right coronary artery from the left anterior descending artery is very rare, with a prevalence of 0.015%, corresponding to 1.2% of all coronary artery anomalies. The authors present the case of a 22-year-old man, with a history of cocaine use, admi...

Coronary artery anomalies are often discovered incidentally during cardiac catheterization or computed tomography coronary angiography and may involve the affected coronary artery origin and its course. Coronary artery anomalies are associated with congenital heart disease. The affected coronary arteries may have an unusual high take off origin, origin from contralateral or non-coronary sinus, ...

the majority of coronary artery fistulas (cafs) are congenital. the anomaly accounts for 0.4% of congenital heart defects and approximately 50% of pediatric coronary vasculature anomalies. twenty percent of people with congenital cafs have other concomitant cardiac anomalies, most frequently aortic and pulmonary atresia and patent ductus arteriosus. it is worthy of note that caf with the tetral...

Coronary artery anomalies are usually incidentally diagnosed at the time of coronary angiography or autopsy. In a large series of 70,850 patients undergoing coronary angiography, the incidence of coronary anomalies was found to be 0.24-1.3%. The majority of these were reported to be anomalies of origin or distribution, with separate ostia of the left anterior descending artery and left circumfl...

BACKGROUND Sudden death risk in Williams syndrome (WS) patients has been shown to be 25-100 times higher than in the general population. This study aims to detect coronary artery anomalies and myocardial perfusion defects in WS patients using noninvasive diagnostic methods. METHODS This study features 38 patients diagnosed with WS. In addition to physical examination, electrocardiography, and...

Advances in 64-row multidetector computed tomography have provided noninvasive imaging of coronary arteries. The aim of this study was to evaluate the prevalence of coronary artery anomalies in Iranian symptomatic patients and to determine the presence of anomalies resulting in myocardial ischaemia without atherosclerotic plaque. This study was carried out in Tabriz University of medical scienc...

Congenital anomalies of the coronary artery causing coronary occlusive disease may be of many different types. A 67-year-old woman with no coronary risk factors was referred for coronary angiography with few months' history of angina. The patient underwent coronary angiography due to ischemic cardiac symptoms with nondiagnostic exercising test. In coronary angiography, the left main coronary ar...

The congenital absence of the left circumflex artery (LCx) is a very rare congenital anomaly of coronary arteries, but it is benign. Currently, the best modality for the diagnosis of coronary anomalies is computed tomography coronary angiography (CTCA). We report a case of congenitally absent LCx with an atypical chest pain.

BACKGROUND As coronary computed tomography angiography (CCTA) has emerged as a non-invasive alternative for evaluation of coronary anatomy with a lower referral threshold than invasive coronary angiography (ICA), the prevalence of coronary anomalies in CCTA may more closely reflect the true prevalence in the general population. Morphological features of coronary anomalies can be evaluated more ...
