Bottom Line: It can be mostly found in mediastinum or lung.We found 2 cases in more than 20000 cardiac surgical cases in our department.It is recommended to complete resection of any bronchogenic cyst for primarily diagnostic and potentially therapeutic reasons, and every effort should be made to prevent complications due to injury to nearby tissues.

ABSTRACT
Bronchogenic cyst is considered as an uncommon congenital anomaly. It can be mostly found in mediastinum or lung. Intracardiac bronchogenic cyst is very rare. We found 2 cases in more than 20000 cardiac surgical cases in our department. The 2 cases bronchogenic cyst arose from interatrial septum (IAS), the preoperative diagnosis were myxoma, but the histological diagnosis were bronchogenic cyst in both cases. Although it is very rare, it should be considered while intracardiac tumor is diagnosed. It is recommended to complete resection of any bronchogenic cyst for primarily diagnostic and potentially therapeutic reasons, and every effort should be made to prevent complications due to injury to nearby tissues.

Figure 1: Transthoracic echocardiography showing a 3.2 × 2.7 cm mass in the RA attached to interatrial septum. (LA = left atrium; LV = left ventricle; RA = right atrium; RV = right ventricle; T = tumor).

Mentions: A 36-year-old woman with a short history of palpitation and mild dyspnea on exertion was admitted into our clinic, physical examinations and the chest radiograph were within normal ranges, echocardiography showed the ventricular and valve function were normal, a mass of 3.2 × 2.7 cm attached to the IAS was discovered in the right atrium (Figure 1). The preoperative diagnosis was myxoma. The decision was made to resect the tumor. Under a median sternotomy and a standard cardiopulmonary bypass with cold blood cardioplegia, the right atrium was opened, a round cyst with a diameter of 3 cm arising from IAS was revealed, a 2.5 cm atrial septum defect was incidentally found behind the tumor, the lumen of the cyst contained yellow, jelly-like fluid, the cyst was resected completely after the fluid was sucked away, the defect was closed together with the ASD directly with 5/0 Prolene suture. Weaning from extracorporeal circulation was uneventful, the patient was discharged regularly on the 10th day postoperative. No recurrence of the tumor was noted during the 5 year follow-up. Under microscopy, the cyst lining was ciliated columnar epithelium or so-called respiratory epithelium (Figure 2). Immunohistochemistry study showing CK (+)、Vim (+)、actin (−)、s-100 (−). Histology diagnosis was bronchogenic cyst in the interatrial septum.
