  • 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, 2016
    Co-Authors: Yunis Daralammouri, Malik Ghannam, Bernward Lauer

    Abstract:

    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, 2010
    Co-Authors: Andreas Y. Andreou, Panayiotis C. Avraamides, George M. Georgiou

    Abstract:

    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, 2009
    Co-Authors: Andreas Y. Andreou

    Abstract:

    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, 2016
    Co-Authors: Onur Baydar, Veysel Oktay, Ugur Coskun, Ahmet Yildiz, Tevfik Gürmen

    Abstract:

    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.
