Dual Left Anterior Descending Artery Arising From Left Circumflex Artery With an Intramyocardial Coronary Aneurysm

Dual left anterior descending (LAD) artery is a rare anomaly conventionally classified into 4 types. We present a case of dual LAD artery in which the long LAD artery has arisen from the left circumflex (LCx) artery, a condition not previously included in the 4 defined types. Moreover, the long LAD artery specified here is associated with an intramyocardial coronary aneurysm. To our best knowledge, it is the first time such a coronary artery anomaly has been reported. This case suggests the important role of coronary computed tomography angiography (CTTA) for diagnosis and therapeutic planning for such an anomaly.     

Dual Left Anterior Descending Coronary Artery: A Rare Coronary Anomaly

We were asked to review the coronary angiogram of a patient showing a dual left anterior descending (LAD) arterial supply anomaly. This prompted a review of the database at Ochsner Foundation Hospital for congenital coronary anomalies in general and similar cases in particular. Between 1989 and 1996, 15,714 coronary catheterizations were performed. We found 134 anomalies (0.85%); the presence of a dual supply to the usual LAD territory was found in 2 patients (0.013%). In this report, we present the absolute and relative incidence of the individual patterns.     

Single Coronary Artery: Right Coronary Artery Originated From Middle of Left Anterior Descending Artery in a Patient With Severe Mitral Regurgitation

The single coronary artery is a benign and very rare coronary artery abnormality. Anomalous origin of the right coronary artery originating from the left anterior descending artery has been reported previously in just a few cases. In this article, we presented a patient with an anomalous origin of the right coronary artery from the midportion of the left anterior descending artery. The anomalous coronary artery was discovered incidentally during a coronary angiography performed prior to mitral valve surgery. Copyright © 2010 Wiley Periodicals, Inc.     

SequentiaI RevascuIarization of Intramuscular Left Anterior Descending Coronary Artery

A bstract We present a new technique for avoiding possible kinking or angulation of the sequential left internal mammary artery to left anterior descending artery (LIMA-LAD) anastomoses when the LAD follows an intramuscular course. A 3- to 5-mm cusp of saphenous vein segment is interposed between the intramuscular LAD segment and internal mammary artery (IMA) at the sequential anastomotic site, to which the distal portion of the IMA was anastomosed in standard end-to-side fashion.     

Giant Left Anterior Descending Artery Aneurysm in a Patient with Behcet's Disease

Coronary artery aneurysm is a rare coronary abnormality nearly half of which originates from atherosclerotic lesions. The major causes of non-atherosclerotic coronary aneurysms include coronary ectasia, Kawasaki disease, Takayasu aortitis, thoracic trauma and complicated angioplasty; however, it has been rarely reported associated with Behcet's disease.
