摘要

Abstract Background Primary cardiac adipose tumors are rare. There are two distinct pathologically defined entities that represent this tumor type: lipoma and lipomatous hypertrophy of the interatrial septum (LHIS). We present a single‐center experience with these tumors and demonstrate that the location may not correspond to the pathologic diagnosis. Methods A retrospective review of a prospectively collected cardiac surgery database from January 1990 to July 2016 identified 254 cases of surgically treated primary cardiac tumors at our Institution. Of these, 06/254 (2%) were primary adipose tumors. Results In 3/6 (50%) cases, patients were asymptomatic or had symptoms referable to other known intracardiac lesions. Five patients (83%) had preserved ventricular function. In 4/6 cases (67%), the tumor was identified preoperatively. All patients presented in New York Heart Association functional class ≤2. Pathologic diagnosis of LHIS was made in 5/6 cases (83%), with 2/5 LHIS (40%) located in the interatrial septum. A bovine pericardial patch was utilized for reconstruction following tumor resection in 3/6 cases (50%). Mean cardiopulmonary bypass time was 88?±?43?min. All the patients tolerated the procedure well without any postoperative complications. Conclusions Primary cardiac adipose tumors are responsible for a small portion of all primary heart tumors. Surgical resection provided excellent outcomes, and did not affect cardiac performance, in spite of the need for extensive resections. LHIS was identified in locations other than the interatrial septum and was usually symptomatic.
