Abstract

The presentation of a cardiac hamartoma, an exceedingly rare and histologically benign cardiac tumor, can be variable. We describe a case of refractory ventricular tachycardia in a patient with a cardiac mass failing multiple pharmacologic and procedural interventions, ultimately treated by cardiac transplantation and diagnosed with a mesenchymal cardiac hamartoma. (Level of Difficulty: Intermediate.).
