Septal branch of anterior interventricular artery at a glance
- What it is
- One of the septal branches of the left anterior descending artery.
- Location
- These branches arise from the anterior interventricular artery and enter the interventricular septum.
- Function
- They supply the anterior two thirds of the interventricular septum, including parts of the conduction system.
- Body system
- Cardiovascular · single, midline structure
- FMA ID

Key facts
- The first septal perforator is a target for alcohol septal ablation in hypertrophic cardiomyopathy.
Clinical relevance
Occlusion can cause septal infarction and conduction block.
