Progressive Thinning of the Basal Interventricular Septum by Giant Cell Myocarditis

Abstract

We describe a patient with ventricular tachycardia and complete atrioventricular block. Remarkable thinning of the basal interventricular septum preceded left ventricular dysfunction. Endomyocardial biopsy demonstrated giant cell myocarditis. The patient received combined immunosuppressive therapy and a cardioverter-defibrillator. Eligibility screening for heart transplantation was initiated. (Level of Difficulty: Advanced.)
