A rare anomaly of the aortic arch complex

A six-month-old girl presented with heart failure. Cardiac catheterisation showed a ventricular septal defect and an anomaly of the aortic arch complex, which is a challenge to embryologic theory.     

Double left anterior descending artery originating from the left and right coronary artery: A rare coronary artery anomaly

A case of double left anterior descending coronary artery is presented. The double artery originated from the left main stem and the right coronary artery. There were no stenoses on these two arteries. This anomaly of coronary arteries seems to be very rare. © 1993 Wiiey-Liss, Inc.     

Double left anterior descending artery originating from the left and right coronary artery: A rare coronary artery anomaly

Coronary arteries with anomalous aortic origin are infrequently encountered in patients undergoing cardiac catheterization and pose potential technical difficulties for performing both diagnostic and angioplasty procedures. Percutaneous transluminal coronary angioplasty (PTCA) of atherosclerotic disease in anomalous right coronary artery (RCA) has been described in only a few reports. In all the cases reported to date, the anomalous vessel arose from the left sinus of Valsalva. We report a case of a technically straight-forward PTCA performed in an anomalous RCA arising from the anterior aspect of the ascending thoracic aorta. © 1994 Wiley-Liss,Inc..     

A rare coronary artery anomaly: anomalous right coronary artery arising from the left anterior descending artery

Anomalous right coronary artery is a rare entity with an incidence of 0.26%. The anomalous origin usually arises from the left sinus valsalva. An anomalous right coronary artery arising from the left anterior descending artery is rare. It is usually known as a benign entity but may have clinical importance due to its course between the aorta and pulmonary artery which may cause myocardial ischemia or sudden cardiac death. Here we present an anomalous coronary artery arising from the left anterior descending artery detected by coronary artery angiogram and confirmed by multislice computed tomography thereafter. 40% retrospective electrocardiographic gating is performed and volume-rendered 3 D and axial MIP (maximum intensity projection) images were reconstructed on a Vitrea post- processing Workstation. The images demonstrated the anomalous origin of the right coronary artery arising from the proximal portion of left anterior descending artery after the first septal perforator and coursing.     

A rare anomaly of the aortic arch: aberrant right subclavian artery associated with common carotid trunk

With increasing use of transradial access (TRA) to perform coronary angiography, arterial anomalies of the upper extremity are more frequently encountered. We describe a patient with an aberrant right subclavian artery (RSCA) originating as the last major branch of the aortic arch, which eventually led to failure of the transradial approach. Subsequent arch aortography revealed an associated common carotid trunk. The combination of both anomalies is a rare finding and may be associated with a number of other arterial and/or mediastinal organ anomalies.     

Single right coronary artery continuing as left circumflex artery and hypoplastic left anterior descending artery: a rare coronary anomaly

The occurrence of a single coronary artery (SCA) is rare in the absence of other associated anomalies of the heart and is often detected incidentally during coronary angiography. This anomaly is usually benign and various types of SCA have been described. We report a rare type of SCA originating from the right sinus of Valsalva, with the left circumflex artery (LCX) continuing from right coronary artery (RCA) and hypoplastic left anterior descending artery (LAD), which was incidentally found in a 63-year-old female presenting as unstable angina.     

Double left anterior descending coronary artery arising from the left and right coronary arteries: a rare congenital coronary artery anomaly

Double left anterior descending coronary artery arising from the left and right coronary arteries is a very rare congenital coronary artery anomaly. In this report, we describe a patient with double left anterior descending coronary artery originating from the left and right coronary arteries. To the best of our knowledge, dual connection of the left anterior descending coronary artery to the left and right coronary arteries has been described in only five patients.     

Left aortic arch, retro-esophageal aortic segment, right descending aorta and right patent ductus arteriosus--a very rare "vascular ring" malformation

A vascular ring formed by a left aortic arch, a retro-esophageal segment, a right descending aorta and right-sided ductus or ligamentum arteriosum is a very rare anomaly up to now; only 16 cases have been reported in the literature. This report presents the case of an infant suffering from the symptoms of airway and esophageal compression, who was successfully operated on for this anomaly at the age of 5 months. The diagnosis was established by means of esophagogram and angiography. Diagnostic criteria and guidelines for therapy are discussed.     

Double left anterior descending artery arising from the left main stem and right sinus of Valsalva: an extremely rare coronary artery anomaly

A case of double left anterior descending artery is presented. One originated from the left main stem and the second one originated from the right sinus ofValsalva. This is an extremely rare variety of congenital coronary artery anomaly. By an extensive review of the medical literature, we were able to find only four similar cases.     

Coarctation of the descending aorta. A rare form of connatal aortic stenosis

A clinical diagnosis of a coarctation of the aorta was made in a 17-year-old female hypertensive patient. Angiography revealed an atypical stenosis of the descending aorta which was surgically corrected. The causes of aortic stenoses are discussed.     

Anomalous left anterior descending artery from pulmonary artery: An extremely rare coronary anomaly

We report a rare coronary artery anomaly–anomalous origin of the left anterior descending artery from the pulmonary artery in a 40-year-old woman. The uniqueness of this case is the absence of any significant morbidity from this condition in adulthood which is in contrast to other reported cases where patients present with myocardial infarction, congestive heart failure, and sometimes death during the early infantile period.¹     

A rare form of communication between the left internal thoracic artery and the left anterior descending artery

Extracardiac collaterals generally from bronchial and internal thoracic arteries to coronary circulation have been described in the literature. In this report, we present a case of 59-year-old male patient with collaterals from the left internal thoracic artery to the left anterior descending artery developed after coronary artery bypass grafting and aneurysmectomy surgery. It is likely the collaterals developed as a result of the postoperative adhesions.     

Vascular anomaly - left anterior descending artery originating from right coronary sinus

A case of a patient with congenital anomaly of coronary blood vessels with left anterior descending artery starting from right coronary sinus is presented. The patient was operated on due to symptoms of myocardial ischaemia by carrying out an off-pump coronary artery bypass graft to left anterior descending artery and obtuse marginal artery, with a very good outcome.

右位主动脉弓、右位降主动脉、迷走左锁骨下动脉伴Kommerell憩窜/动脉瘤较为少见,动脉瘤容易发生夹层、破裂而死亡.肥厚型心肌病(HCM)是以心肌肥厚、心肌纤维排列紊乱为特征的一组临床表现,猝死发生率较高.我院高血压诊治中心于2007年10月收治一例同时患有肥厚型梗阻性心肌病、右位主动脉弓、右位降主动脉、迷走左锁骨下动脉伴Kommerell憩室合并壁内血肿患者,目前国内外文献均未见报道.     

A previously undescribed anomaly of left anterior descending artery: type V dual left anterior descending artery

Dual left anterior descending coronary artery (LAD) is a group of rare congenital coronary artery anomalies and exhibits 4 different types. The goal of this article is to define a new, previously undescribed type of dual LAD anomaly.
