New congenital coronary artery anomaly – double supply of single left Anterior descending coronary artery from the left and right coronary sinuses: a case report
Journal of Medical Case Reports, 2016Co-Authors: Yunis Daralammouri, Malik Ghannam, Bernward LauerAbstract:Background A normal anatomy of coronary arteries is important to have adequate cardiac muscle blood supply especially during extraneous physical activities. This case report describes a rare coronary anomaly in which the accessory coronary artery arose from the right coronary artery, reentered the left Anterior descending coronary artery, and then ran as a single vessel. Case presentation We present a case of a coronary anomaly in a 47-year-old white man who presented with atypical angina. Computed tomographic angiography and coronary angiography showed a variant of dual left Anterior descending coronary artery not previously described. Our patient’s accessory coronary artery arose from his right coronary artery. It took an intramuscular course beneath the right ventricular outflow tract in the Interventricular septal area to the Anterior Interventricular Sulcus, giving off septal perforators that reentered his medial left Anterior descending coronary artery. Both vessels ran after the anastomosis in the Anterior Interventricular Sulcus as a single vessel. Conclusions We propose that this anomaly represents a new variant of coronary artery anomaly. This coronary artery anomaly does not cause ischemia. Recognition of this coronary anomaly is important in patients undergoing percutaneous coronary intervention or coronary artery bypass graft operations.

Dual Anterior Interventricular artery type IV: a rare anatomical variation
Surgical and Radiologic Anatomy, 2010Co-Authors: Andreas Y. Andreou, Panayiotis C. Avraamides, George M. GeorgiouAbstract:Type IV dual Anterior Interventricular artery (AIVA) is a rare variant that involves bilateral connection of this vessel to the left main coronary artery and right coronary artery or right aortic sinus. We present a case of such a variant where the ectopic branch traveled an intraseptal course, i.e., through the superior aspect of the crista supraventricularis in a subendocardial position and then intramyocardially inside the upper Interventricular septum to reach the Anterior Interventricular Sulcus and descend toward the apex. In a left Anterior oblique view, this course lacked the typical caudal Anterior loop but it was recognized by virtue of emergence of a septal branch as the first branch of the ectopic AIVA. Recognition of this variant and differentiation among the possible courses of the ectopic branch is important for patient management.

The parallel left Anterior descending coronary artery.
International Journal of Cardiology, 2009Co-Authors: Andreas Y. AndreouAbstract:The left Anterior descending artery (LADA) is defined as the vessel that travels in the Anterior Interventricular Sulcus (AIVS) supplying septal branches to the Anterior Interventricular septum. Duplication of the LADA entails that two vessels are located in the AIVS. This report presents some comments regarding a case of the so called "parallel LADA" which has been erroneously recognized as dual LADA.

A Rare Case of Type IV Dual Left Anterior Descending Coronary Artery.
Journal of clinical and diagnostic research : JCDR, 2016Co-Authors: Onur Baydar, Veysel Oktay, Ugur Coskun, Ahmet Yildiz, Tevfik GürmenAbstract:Coronary artery anomalies are usually asymptomatic and associated with other cardiac malformations. Dual left Anterior descending coronary artery (LAD) is an uncommon congenital anomaly with four subtypes. This anomaly has been described in the angiographic literature and dual LAD types depending on the origin of major septal and diagonal branches and course within the Anterior Interventricular Sulcus. Type IV expresses the anomaly of a rudimentary LAD artery ending in the mid-portion of the Anterior Interventricular Sulcus, and the presence of other LAD originating from the right coronary artery and continuing to the Anterior Interventricular Sulcus. We report the rare case of a patient with the type IV dual left Anterior descending coronary artery.

Dual (type IV) left Anterior descending artery
South African Medical Journal, 2013Co-Authors: O. Baskan, Cengiz Erol, Yahya PaksoyAbstract:Congenital coronary artery anomalies are uncommon. Dual left Anterior descending coronary artery (LAD) is defined as the presence of two LADs within the Anterior Interventricular Sulcus (AIVS), and is classified into four types. Type IV is a rarely reported subtype and differs from the others, with a long LAD originating from the right coronary artery (RCA). Dual LAD is a benign coronary artery anomaly, but should be recognised especially before interventional procedures. With the increasing use of multidedector computed tomography (MDCT), it is essential for radiologists to be aware of this entity and the cross-sectional findings.

Primary percutaneous coronary intervention in patient with dual left Anterior descending artery
Revista Brasileira de Cardiologia Invasiva (English Edition), 2020Co-Authors: Ricardo De Souza Alves Ferreira, José Luis Attab Dos Santos, Clemente Greguolo, José Fábio Fabris, Marcelo D’anzicourt Pinto, Renato Sanchez AntonioAbstract:Abstract The anatomy of the coronary arteries is well known, but there is a wide variety in their origin and distribution. The dual left Anterior descending artery is defined as the presence of two left Anterior descending arteries within the Anterior Interventricular Sulcus and is classified into four types. It is a benign anatomical variant that should be recognized, especially before interventional procedures. We report a patient with type I dual left Anterior descending artery, with acute Anterior wall ST elevation myocardial infarction, referred for primary percutaneous coronary intervention.
