Atrial Hemangioma: A Case Report and Review of the Literature.

A primary cardiac tumor is a rare clinical entity which was reported an incidence of 0.03% in previous autopsy series. 75% cardiac tumors are cardiac myxoma and cardiac hemangiomas constitute only 1-2% of primary cardiac tumors. With the development of modern medical imaging technology and the enhancement of people's health awareness, more and more asymptomatic cardiac hemangiomas were found and confirmed eventually. Here, we described a case of a 71-year-old man, who was hospitalized with intermittent palpitation for 1 year and a large mass of the heart was removed successfully via sternotomy which was confirmed as atrial hemangioma by postoperative histopathology. Furthermore, a comprehensive review of atrial hemangioma was conducted to date and a few recommendations for the diagnosis and treatment of this uncommon disorder were provided for clinicians.
