septal perforating artery

The septal perforating artery is an artery that branches from the left anterior descending artery and is involved in supplying blood to the interventricular septum of the heart.

Septal perforating arteries are located within the interventricular septum, arising perpendicularly from the left anterior descending artery and penetrating into the septal myocardium.

The septal perforating artery is involved in delivering oxygenated blood to the myocardium of the interventricular septum, including the conduction system components such as the bundle branches that are located there.

Anterior myocardial infarction due to left anterior descending artery occlusion, ventricular septal defect post-infarction, or hypertrophic obstructive cardiomyopathy treated with alcohol septal ablation may involve the septal perforating arteries.

Septal perforating arteries may be assessed through coronary angiography, CT coronary angiography, or cardiac MRI with late gadolinium enhancement to evaluate septal myocardial viability and perfusion.
