Intervenção coronária percutânea primária em paciente com artéria descendente anterior dupla

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.
