Coronary Artery-Left Atrial Fistula Complicated by a Left Atrial Myxoma：Report of a Case

はじめに　他疾患の術前CTで左房内腫瘤を指摘され，心臓手術の術前検査の冠状動脈CTで冠状動脈の異常血管を指摘された症例を経験した．手術は腫瘍切除と異常血管の結紮で良好な結果を得た．まれな症例と思われるので報告する．

We report our experience with a case of a left atrial mass coexisting with a coronary artery-left atrial fistula. The abnormal vessels extended from the right coronary artery and left circumflex artery to the tumor in the left atrium and were aggregated within the tumor. An efflux of the contrast media was also noted from the tumor into the left atrium. Tumor resection and ligation of the abnormal vessels were performed as surgical interventions. The outcomes were favorable. The tumor was pathologically diagnosed as a myxoma, but its association with the abnormal vessels was unknown.
