Bronchogenic cysts are classified as a type of congenital foregut cyst. They are usually extrapulmonary and occur mostly along the tracheobronchial tree. Intracardiac bronchogenic cysts are very rare. As far as we know, only 3 cases have been reported previously. This paper presents a unique case of a 70-year-old male who was diagnosed with a bronchogenic cyst in the interatrial septum with a concomitant persistent left superior vena cava. He underwent successful complete excision of the cyst under cardiopulmonary bypass and enjoyed an uneventful life with normal sinus rhythm during the 1-year follow-up. The relevant literature is reviewed and an explanation for the embryogenesis of the bronchogenic cyst in such a peculiar location is proposed.
支气管源性囊肿被归类为一种先天性前肠囊肿。它们通常位于肺外，大多沿着气管支气管树分布。心内支气管源性囊肿非常罕见。据我们所知，此前仅报道过3例。本文介绍了一例独特病例，一名70岁男性被诊断为房间隔支气管源性囊肿，同时伴有永存左上腔静脉。他在体外循环下成功完整切除了囊肿，在1年的随访期间窦性心律正常，生活平稳。本文回顾了相关文献，并对这种特殊位置的支气管源性囊肿的胚胎发生机制提出了解释。
