Objective To study the clinical, diagnostic features and surgical therapy of left atrial myxoma. Method 30 cases of left atrial myxoma were admitted for symptoms of palpitation and anhelation after labor or tiredness. All the cases were diagnosed by UCG and then operated under cardiopulmonary bypass. The mean aorta clamping time was 23.7 min(range 11～40 min). Results 24 cases of the group discharged with recovered heart function. 6 cases died in early post operative period for arrhythmia, low cardial output syndrome and multiple systemic organ failure. Conclusion Left atrial myxoma is recognized as a common benign cardiac neoplasm. Early diagnosis and timely operation to avoid complications are very important to the patients.
