Research focus: Left anterior descending (LAD) artery branching anomalies are normally asymptomatic and occur with a frequency of less than 1%, and thus, are typically discovered incidentally. The aim of this report is to present a case of an aberrant LAD with special attention to the implications of its subsequent course. A 68-year-old female with acute chest pain was admitted for evaluation, including cardiac catheterization. Results from her catheterization included an ejection fraction of 60-65%, a left coronary artery free of disease, and a right coronary artery free of disease from which the left anterior descending (LAD) artery was found to atypically arise. The LAD artery was noted to course between the ascending aorta and pulmonary artery with positional narrowing of the LAD and surgical revascularization recommended.
