A 68-year-old female with a complaint of chest pain and negative stress test Lexiscan was found to have a right atrial mass on transthoracic echocardiogram [Figure 1]. Cardiac magnetic resonance imaging showed a lobulated mass consistent with a lipoma in the right atrium encircling the superior vena cava (SVC) entrance with extension to the lateral wall and septum [Figure 2]. Intraoperatively, the mass was found to be subendocardial and not completely discrete from surrounding tissues. The mass was resected as completely as possible, and the right atrium was reconstructed with a bovine pericardial patch. Following separation from cardiopulmonary bypass, the patient developed engorgement of the head and upper body consistent with SVC obstruction and required revision with a patch cavoplasty. Due to persistent signs of residual SVC obstruction postoperatively, the patient then underwent percutaneous stenting of the SVC with subsequent complete resolution of upper body edema [Figure 3]a and [Figure 3]b. The pathology showed mature adipose tissue admixed with cardiac muscle consistent with lipomatous hypertrophy. The patient's hospital course was otherwise uneventful.
