“…The term "double ADA" refers to a variation of the anterior descending artery, in which two different arteries partially or totally supply the same territorial regions. The anomaly is characterized by the presence of two separate components of the Figures 6 and 7 (Saremi et al, 2013;Bozlar et al, 2015).…”

With the increase in coronary procedures, understanding the anatomical patterns of the coronary arteries is becoming increasingly crucial, since they can result in implications for the patient. The aim of this study was to carry out a detailed analysis of the coronary arteries of hearts from the Human Anatomy and Pathology Laboratory at the University of Uberaba (UNIUBE). This topic was selected due to its relevance in understanding pathological changes resulting from alterations in blood flow. A cross-sectional analytical observational study was carried out over a period of 20 months: August 2022 to April 2024. The material for the study consisted of 40 preserved cadaveric hearts and data collection was based on a script with previously prepared questions, according to the cardiac anatomy described in the literature. In the study carried out, of the total number of hearts analyzed, four had an irregular coronary pathway, representing a total of 10%. Based on the universally accepted coronary branching pattern, 13 alterations were found, representing a total of 33%. Among them, the main and rarest was the double origin of the anterior descending artery, with one branch originating from the right coronary artery and one from the left coronary artery. Regarding the pattern of coronary dominance, right dominance was predominant in 87% of cases. In general, the research will contribute to a better understanding of the importance of cardiac anatomy for the understanding of clinical events, for the correct performance and interpretation of examinations and for the surgical approach to patients.

“…The incidence of double ADA varies from 0.68 to 6% in different case series (Bozlar et al, 2015). It refers to a variation of the anterior descending artery, in which two distinct arteries provide vascular supply to part or all of their shared territorial areas (Saremi et al, 2013).…”

“…In a left or codominant coronary artery system, the atrioventricular nodal artery may arise from the terminal left circumflex artery or, uncommonly, from both the right coronary artery and the left circumflex coronary artery (25)(26)(27). On rare occasions, the atrioventricular nodal artery arises from the proximal right coronary artery, as a continuation of the right superior septal artery or the Kugel artery (28,29). A rare variant of this is shown in Figure 16.…”

The septal atrioventricular junction is a centrally located region of the heart where the septal components of the atria and ventricles meet the aortic, mitral, and tricuspid valves. Important structures in this region include the membranous septum, the central fibrous body, the Koch triangle, the inferior pyramidal space, and the base of the interventricular septum. This small area is the home of the atrioventricular node and the atrioventricular conduction axis and has enormous importance to electrophysiologists owing to its prime role in the conduction system of the heart. The atrioventricular node lies within the triangle of Koch; and the atrioventricular bundle, or bundle of His, exits the atrioventricular node and penetrates the right fibrous trigone and runs underneath the membranous septum. The septal atrioventricular junction is a common location for intracardiac shunts such as membranous and perimembranous septal defects. Imaging classification of these defects can have important implications before surgical closure, because the atrioventricular conduction axis passes along the posteroinferior margin of most perimembranous defects. Extracardiac inflammatory and malignant pathologic conditions can extend from the mediastinum toward the inferior pyramidal space in this region through the epicardial fat planes. Although the anatomic structures are complicated, the components can be shown in exquisite detail with computed tomography (CT). In this review, the anatomic boundaries and important anatomic landmarks are examined with CT and magnetic resonance imaging. Also described are the anatomic variants of the membranous septum pertinent to percutaneous aortic valve implantation, the vascular anatomic variants, and commonly encountered pathologic conditions related to the septal atrioventricular junction.
