Septal infarct is a patch of dead, dying, or decaying tissue on the septum. The septum is the wall of tissue that separates the right ventricle of your heart from the left ventricle. Septal infarct is also called septal infarction.


Septal infarct is usually caused by an inadequate blood supply during a heart attack (myocardial infarction). In the majority of cases, this damage is permanent.


You probably won't know if you have septal infarct unless your doctor discovers it during surgery or while administering an ECG. Once diagnosed, your doctor will most likely recommend appropriate lifestyle changes to lower your risk of cardiovascular disease and heart attack. Your doctor might also prescribe medicine to control your blood pressure or your cholesterol.
