Complete heart block and polymorphic ventricular tachycardia complicating myocardial infarction after occlusion of the first septal perforator with coronary stenting.
We report a case of complete heart block (CHB) and polymorphic ventricular tachycardia (VT) which was associated with a modest-sized myocardial infarction (MI) following incidental occlusion of the first septal perforator (FSP) branch after stent deployment to the left anterior descending (LAD) coronary artery. These complications were successfully treated with temporary pacing and subsequently resolved with spontaneous recanalization of the first septal perforator. This case represents an interesting product of medical progress which defies the adverse natural history and poor prognosis of anteroseptal MI associated with CHB due to the small amount of myonecrosis associated with this event.
