Analysis of data of 21 patients with atrial myxoma

Objective To discuss the diagnosis and surgical treatment of atrial myxoma. Methods Twenty-one cases of atrial myxoma diagnosed by B-ultrasonography and excised under general anesthesia with middle low temperature extracorporal circulation (ECC). Results The ECC time was 38～98 min (mean 45±12.4 min). The time of blocking aorta was 29～78 min (mean 34±11.3 min). All of 15 cases of left atrial myxoma and 6 cases of right atrial myxoma were exercised successfully and without death in period of operation,and they were all myxoma recovered. In followed-up period of 2 years,one patient relapsed and healed after second operation.Conclusion Atrial myxoma should be early operated after diagnosis and pay attention to myocardial preservation,excise the tumour wholly so as to avoid relapse.
