Abstract: Objective  To summarize the clinical experience of simultaneous coronary artery bypass grafting (CABG) and atrial myxoma removal. Methods  Clinical data, surgical methods and prognosis of 18 patients undergoing atrial myxoma removal and CABG in our department from January 2013 to March 2019 were retrospectively analyzed. Results  All patients underwent simultaneous CABG and atrial myxoma removal  under extracorporeal circulation. According to the tumors seen during the operation, the tumor locations were consistent with those observed by cardiac ultrasound. And the tumors were different in sizes and shapes, such as lobulated, irregular and close round appearance. The tumors were brittle, most of them were gelatinous and few possessed envelope with mucus effusion, bleeding or calcification on the surface.  A few parts of tumors can fall mitral or tricuspid valve mouth.  There were no postoperative deaths. One case with postoperative low cardiac output syndrome was cured after corresponding treatment. There were 5 patients with newly atrial fibrillation after operation, and all of them returned to normal after treatment with amiodarone. Two patients underwent  rethoracotomy for hemostasis. After the postoperative followup of one year, no tumor recurrence was found in 18 patients, and their cardiac function returned to NYHA ⅠⅡ. Conclusion  The simultaneous removal of atrial myxoma and CABG are effective methods for treating atrial myxoma complicated with coronary heart disease, which can achieve a good prognosis.
