Abstract

A 44‑year‑old male patient was referred to our department with unremarkable physical examination and laboratory data due to a mass which was incidentally found in the right atrial during a routine examination.Transthoracic and transesophageal echocardiography revealed a 46×30 mm, well-delimited, non-mobile mass in the superior portion of the right atrium. Besides the intracardiac mass, another low density was detected in adjacent pericardial cavity at cardiac computed tomography ;he extracardiac mass appeared to be caused by invasive growth from the intracardiac mass.An operation was performed through right anterolateral minithoracotomy with the patient under hypothermic cardiopulmonary bypass. During operation, it was found that the surface of the right atrium was covered by an adipose mass (30×40 mm; Fig. 2A). Intracardiac mass also showed yellow adipose tissue (40×50 mm; Fig. 2B). Both parts of the mass infiltrated the myocardium. The mass was resected completely; and right atrium was reconstructed by using bovine pericardium pad. After the operation, the pathology confirmed the both intracardiac and extracardiac tissues as lipoma; transthoracic echocardiogram showed the atrial mass was removed completely and the left ventricular ejection fraction was normal . The patient’s postoperative course was uneventful and he was discharged home after 7 days.
