title: Clinical Features and Surgical Results of Right Atrial Myxoma.
abstract: BACKGROUND
  We retrospectively analyzed 367 patients receiving surgical resection of cardiac myxomas in our center over six years, and analyzed the incidence and surgical results of 28 cases of right atrial myxomas. We also compared the age, gender, and attached sites between left atrial myxoma and right atrial myxoma.
  
  
  METHODS
  Between January 2007 and December 2012, 28 patients with right atrial myxomas underwent surgical resection. There were 16 males and 12 females. The mean age was 47.77 ± 13.20 years (range: 8.00-79.00 years). Associated cardiac lesions included moderate and severe tricuspid regurgitation in four, coronary atherosclerotic heart disease in five, and pulmonary embolism in one. Twenty-seven patients (96.43%) were followed from 26 to 94 months (mean 55.78 ± 21.10 months).
  
  
  RESULTS
  There was no early death after operation. The incidence of right atrial myxomas among sporadic cardiac myxomas was 7.89%. One patient died of lung cancer 34 months after myxoma resection. Two patients underwent coronary artery stent implantation due to coronary atherosclerotic heart disease during the follow-up period. One patient underwent myxoma resection due to recurrence in the left atrium four years after the first operation. There was no significant difference in the age between left atrial myxoma and right atrial myxoma (p > 0.05). There was a significant difference in the gender between left atrial myxomas and right atrial myxomas (p < 0.05). The most common attached sites of left atrial myxomas and right atrial myxomas are the atrial septum.
  
  
  CONCLUSIONS
  Surgical resection of the right atrial myxoma results in good clinical outcomes and a decreased incidence of recurrence.
