経心房中隔左房上縁到達法により切除したクマジン稜起源の左房粘液腫の1例

Resection of a Myxoma Orginating from the Coumadin Ridge with Superior Transseptal Approach：Report of a Case

はじめに　粘液腫は一般に心房中隔に多発するが，われわれはクマジン稜に発生したまれな粘液腫の症例を経験した．経心房中隔左房上縁到達法により良好な視野を確保し，粘液腫の一塊切除が可能であった．文献的考察を加えて報告する．

A 70-year-old man with a history of lacunar stroke about a year before was incidentally found to have primary cardiac tumor during the work up for orthopedic surgery. It uniquely originated from the coumadin ridge between the left upper pulmonary vein and the left atrial appendage. He underwent tumor resection under cardiopulmonary bypass with superior transseptal approach. It allowed enough surgical exposure for en-bloc resection of the tumor with minimal risk of tumor embolisms. The pathological report confirmed that the tumor was a cardiac myxoma. The postoperative course was uneventful with no stroke nor embolism complications. We experienced a rare myxoma orginating from the coumadin ridge and successfully resected it with superior septal approach.
