Tubbs R Shane - - 2007
The authors report an adult individual found to have very unusual origins of additional left and right pericallosal arteries that are normally only branches of the anterior cerebral artery. These vessels both arose from the vertebrobasilar system. The right accessory pericallosal artery was found to originate from the ipsilateral posterior ...

Anomalous origin of the right coronary artery is an extremely rare anomaly. We describe the case of a patient whose right coronary artery was arising from the ascending aorta with high takeoff. We diagnosed the anomaly incidentally during the operation. After transverse aortotomy for aortic valve replacement, we recognized the ...

Autopsy studies have associated congenital coronary anomalies with the risk of sudden cardiac death. However, not all patients with anomalous coronary arteries die suddenly. A means of assessing the potential for ischaemia and thus predicting the risk of sudden death in these patients may be necessary for directing treatment. We ...

Coronary artery anomalies (CAAs) are a diverse group of congenital disorders whose manifestations and pathophysiological mechanisms are highly variable. The subject of CAAs is undergoing profound evolutionary changes related to the definition, morphogenesis, clinical presentation, diagnostic workup, prognosis, and treatment of these anomalies. To understand the clinical impact of CAAs, ...

Congenital anomalies of the coronary arteries occur in 0.2% to 1.2% of the general population. Most coronary artery anomalies are found incidentally during angiographic evaluation for other cardiac diseases. We describe the case of a young woman presenting with chest discomfort and fatigue where echocardiography identified a coronary artery fistula. ...

Anomalous left coronary artery from pulmonary artery (ALCAPA) is a rare congenital cardiac malformation. It presents predominantly in infancy with features of myocardial ischaemia or cardiac failure and may be mistaken for common paediatric conditions such as colic, reflux or bronchiolitis. With early surgical correction the prognosis is good, but ...

The purpose of this study was to determine non-invasively the frequency of ectopic bronchial arteries (BA) (i.e., bronchial arteries originating at a level of the descending aorta other than T5-T6 or from any aortic collateral vessel) on multidetector-row CT angiograms (CTA) obtained in patients with hemoptysis. Over a 5-year period ...

Anomalous origin of the right coronary artery (RCA) is a rare congenital anomaly, which may cause myocardial ischemia and sudden death. However, the causes of myocardial ischemia remain uncertain. Multidetector row computed tomography (MDCT) was performed in a 22-year-old woman who had exercise-induced myocardial ischemia. MDCT revealed a small orifice ...

Resynchronization may play a significant role in recovery following surgical reimplantation of anomalous left coronary artery from the pulmonary artery (ALCAPA). Three-dimensional echocardiography and tissue Doppler may quantify this recovery. A 6-week-old infant presented with signs of congestive heart failure due to ALCAPA. Two-dimensional echocardiography showed a severely dilated left ...

The majority of anatomical textbooks offer very little information concerning the anatomy and distribution of the superior phrenic artery (SPA). However, in the last decade, a number of reports have appeared with reference to the transcatheter arterial chemoembolization of the collateral arterial supply of hepatic carcinoma (HC). Considering the potential ...

BACKGROUND: Anomalous origin of the left circumflex coronary artery from the right sinus of Valsalva or proximal right coronary artery is the most common congenital coronary anatomical abnormality. Whether such vessels are particularly predisposed to atherosclerotic disease in their proximal portion remains controversial. Successful balloon angioplasty has been described, but ...

A 3-year-old girl with fever of unknown origin after a visit to Surinam was seen at our hospital. Signs and symptoms were indicative of either Kawasaki syndrome or an acute viral or (atypical) bacterial illness. No cardiac abnormalities were noted at echocardiography. She was treated with intravenous immunoglobulin and clarithromycin ...
Berbarie Rafic F - - 2006
The accurate diagnosis of anomalous coronary arteries by invasive angiography is limited by the inability to define the anatomic course in relation to surrounding structures. Computed tomographic coronary angiography has recently emerged as a noninvasive method to visualize the coronary arteries. Multislice computed tomography with up to 64 detector arrays, ...
