Septal infarction and complete heart block following percutaneous coronary intervention of the left anterior descending coronary artery.
Occlusion of septal perforator arteries may lead to angina, myocardial infarction, arrhythmias, atrio-ventricular (AV) block and heart failure. Percutaneous coronary intervention (PCI) on septal arteries has been performed to alleviate anginal symptoms. We describe the case of a patient who underwent routine PCI of his proximal left anterior descending (LAD) artery complicated by septal artery occlusion, septal infarction and the development of complete heart block. The patient underwent successful balloon angioplasty of the first septal perforator which led to partial recovery of AV conduction and hemodynamic stabilization.
