Abstract

Cardiac hamartomas are a rare type of benign tumor affecting the heart. We describe a 33-year-old patient who presented with a wide complex tachycardia. Diagnostic imaging revealed a mass in the patient’s left ventricular wall, near the apex of the heart. The mass was surgically resected and appeared benign. Its pathology was that of a hamartoma of mature cardiac myocytes. Postoperative electrophysiology evaluation showed no inducible focus and the patient remains alive and asymptomatic after 2 years of follow-up.

Comment

Cardiac tumors are rare and usually benign [1]. Hamartomas are one of the rarest types of benign cardiac tumors, and only small series have been reported in the literature 2, 3, 4, 5, 6, 7, 8. Other benign cardiac tumors, in order of frequency, include myxomas, fibromas, rhabdomyomas, and lipomas.

Recently, Burke and associates reviewed three cases involving hamartomas of mature cardiac myocytes in a 22-year-old patient , 28-year-old patient , and 9-year-old patient [2]. The tumors were
