Double Anterior Interventricular Arteries: Prevalence and Morphological Types-A Dissection Study

This study aimed to evaluate the prevalence of double anterior interventricular artery using the dissection method.

A retrospective study was conducted between 2010 and 2024 at the Anatomy and Embryology Laboratory of the Victor Babes University of Medicine and Pharmacy in Timisoara. Eighty cases were analyzed for morphological variants of the coronary arteries, especially the anterior interventricular artery.

Two cases of double anterior interventricular arteries were identified. In the first case, the two anterior interventricular arteries originated from the anterior interventricular branch of the left coronary artery. In the second case, an additional anterior interventricular artery with an aortic origin was found running along the lower third of the two interventricular grooves. This shape has not been described before in the specialized literature.

Knowing the potential variations of the double left anterior descending artery is critical for interpreting cardiac imaging and choosing and planning percutaneous and surgical reperfusion strategies.
