Anomalous origin of the right coronary artery from the ascending aorta above the noncoronary sinus of valsalva

We describe a patient with an unusual coronary anatomic variant in which the right coronary artery originates from the ascending aorta above the noncoronary aortic sinus of Valsalva. © 1994 Wiley-Liss,Inc..     

Anomalous origin of the left main coronary artery from the right coronary artery ostium-interarterial subtype: Angiographic definition and surgical treatment

Coronary artery anomalies occur infrequently compared to atherosclerotic disease; however, when they do occur, they can pose difficulty with coronary visualization and identification. Ectopic origin of the left mainstem coronary artery from the right sinus of Valsalva coursing between the great vessels is the rarest subtype of these anomalies, can be potentially serious, and presents unique problems for surgical treatment.     

Anomalous origin of the right coronary artery from the left anterior descending coronary artery

A 77-year-old male presented with a recent posterior myocardial infarction for coronary angiography. This angiogram revealed a rare, previously unreported anomalous origin of the right coronary artery from the proximal left anterior descending coronary artery distal to the first major diagonal branch.

Anomalous origin of the right coronary artery arising from the circumflex artery

A case of anomalous origin of the right coronary artery discovered among 3100 selective coronary arteriograms is described. This artery was arising from the circumflex artery. The position, distribution, and configuration of this coronary artery was as a normal right coronary artery, except that its origin was in the peripheral segment of the circumflex artery. This anomalous origin is very rare and seems not to give rise to any clinical significance.     

Anomalous origin of the right coronary artery above the left sinus of valsalva

Various anomalies of coronary arterial origin have been described. These anatomical variations are discovered either by coronary angiography or at autopsy. We are reporting a case of anomalous origin of the right coronary artery above the left sinus of Valsalva. To our knowledge, this anomaly has not been described before. A technique for selectively catheterizing such an aberrant coronary artery is described.     

Anomalous origin of the right coronary artery from the main pulmonary artery: Diagnosis and management

Anomalous origin of the right coronary artery (ARCA) from the main pulmonary artery (MPA) is a rare congenital anomaly, with only 18 reported cases in the pediatric age group. More than half of these had associated cardiac anomalies that masked the presence of ARCA. Conversely, in many patients with ARCA as an isolated anomaly, the diagnosis has been missed during lifetime. The only patient with an isolated ARCA who was diagnosed in infancy presented with congestive heart failure. Asymptomatic infants with ARCA from the MPA have not been previously reported. Three additional cases, two infants and a child with ARCA from the MPA, are reported in this paper. The diagnostic dilemmas and the prognosis are discussed and management is recommended.     

Single left coronary artery with origin of the right coronary artery from distal circumflex

We report two very unusual cases of agenesis of the right coronary ostium with continuation of the left circumflex artery as the right coronary artery. The recognition of the anomaly in the first case lead to a better understanding of this finding in the second case, which translated into shorter procedure time, less contrast volume, and fewer catheter manipulations.     

Triple origin of left coronary arteries from right coronary artery: Unusual case of single coronary artery

A rare case of coronary anomaly is presented: all of the coronary arteries originated from a single ostium located in the right coronary cusp. No clinical evidence of coronary pathology was recognized until the age of 57 years when the patient was found to have coronary obstructive disease. The single coronary artery had a main branch corresponding to the usual dominant right coronary artery. Three other branches separated from this and vascularized the areas normally receiving the circumflex and ramus medianus, the left anterior descending, and a large septal branch.     

Primary percutaneous coronary intervention of an anomalous right coronary artery originating from the left sinus of valsalva

The presence of an anomalous origin of a coronary artery as the infarct related vessel during primary percutaneous coronary intervention for acute ST elevation myocardial infarction is rare and may present a technical challenge. We reported on a primary coronary percutaneous intervention performed in a right coronary artery originating from the left coronary sinus. The technical tips and tricks of treating congenital coronary anomalies are reviewed.     

Anomalous origin of the right coronary artery from the left anterior descending coronary artery

This is the first presentation of anomalous origin of right coronary artery (RCA) from mid-left anterior descending (LAD) coronary artery. A 77-year-old male was catheterized because of recent onset of fatigue during exertion. The LAD demonstrated 50–60% narrowing just proximal to the anomalous origin of the RCA. The patient was maintained on oral medication. Cathet. Cardiovasc. Diagn. 44:328–329, 1998. © 1998 Wiley-Liss, Inc.     

Arteriographic demonstration of both kinking at the origin and compression between the great vessels of an anomalous right coronary artery arising in common with a left coronary artery from above the left sinus of valsalva

Angled angiographic views demonstrated two areas of significant systolic narrowing in an anomalous right coronary artery arising in common with a left coronary artery from above the left sinus of Valsalva: (1) an ostial stenosis due to kinking as the anomalous artery turned sharply to the right after its origin from the aorta; (2) compression of the proximal segment as it coursed between the aorta and pulmonary artery. Appropriate angiographic studies to evaluate the presence of these changes may help to elucidate their significance.     

Anomalous right coronary artery arising from left mainstem

Various coronary artery anomalies occur in both symptomatic and asymptomatic individuals. We have described a unique case of an aberrant right coronary artery arising from the left mainstem, resulting in clinical myocardial infarction in the absence of coronary atherosclerosis. Though different anomalies of the right coronary artery have been described, we feel this case is unique in that the right coronary artery arises from the left mainstem, truly forming a single coronary artery.     

Anomalous right coronary artery from the main pulmonary artery in a patient with double-chambered right ventricle

We describe a rare case of double-chambered right ventricle (DCRV) in a 32-year-old female presenting to the echocardiography lab for evaluation of congenital heart disease. We identified a unique constellation of findings, including the DCRV, a perimembranous ventricular septal defect, aortic valve prolapse, patent foramen ovale, and an anomalous right coronary artery coming off the main pulmonary artery. To the best of our knowledge, this is the first reported case describing the association of an anomalous right coronary artery coming off the main pulmonary artery in a patient with DCRV.     

Anomalous origin of the left coronary artery from the right pulmonary artery: Report of a case

Summary A 1-year-old boy was referred to our hospital for further investigation of mitral regurgitation. Color-Doppler echocardiography revealed the site of the anomalous origin of the left coronary artery which was confirmed by a cineangiographic study. This case is interesting for several reasons: the first is that the anomalous left coronary artery originated from the right pulmonary artery; the second is that two-dimensional echocardiographic findings can be misleading, i.e., a vessel-like structure which seemed to be the left coronary artery arising normally from the aorta was visualized; and the last is that a two-dimensional color-Doppler echocardiogram was useful in the diagnosis of the anomalous origin of the left coronary artery. The patient underwent implantation of the anomalous left coronary artery as well as Kay's plasty of the mitral valve, and has been doing well since then.     

Percutaneous transluminal coronary angioplasty of a right coronary artery arising from the left main coronary artery

Angioplasty of anomalous coronary arteries presents unique technical challenges. Correct guiding catheter selection is important to ensure adequate access to the anomalous vessel and to provide support to cross the lesion. A case of successful PTCA of a lesion in an anomalous right coronary artery arising from the left main coronary artery is presented. © 1993 Wiiey-Liss, Inc.     

Imaging the elusive anomalous origin of left coronary artery from pulmonary artery

A 7‐year‐old girl with severe mitral regurgitation and pulmonary artery hypertension with good ventricular function was planned for mitral valve repair, but was subsequently diagnosed to have anomalous left coronary artery from pulmonary artery. We describe the pitfalls in the diagnosis of this rare anomaly, particularly in the presence of severe pulmonary artery hypertension and absence of circumstantial evidence of coronary steal and ventricular dysfunction.     

Anomalous origin of the right coronary artery from the ascending aorta

A 47 yr-old man had an anomalous origin of the right coronary artery from the left anterior wall of the ascending aorta. This was demonstrated by aortography and by selective right coronary angiography.     

Anomalous origins of the left coronary arteries from the right sinus of Valsalva with an unusual course

We report and attempt to classify a previously undescribed coronary artery anomaly. Our patient had all three coronary arteries arising from a common ostium in the right sinus of Valsalva, with an unusual distribution to the left coronary artery system: the anomalous left circumflex system taking an intraseptal (intramyocardial) course and the anomalous left anterior descending system taking an interarterial (between the great vessels) course.
