    Abstract
  •   Objective  To investigate the clinical features and prognosis of right atrial myxomas and summarise the experience of surgical treatment.  Methods  From January 2008 to December 2018, 12 cases (6 males and 6 females) of right atrial myxomas underwent surgical resection under mild hypothermic cardiopulmonary bypass (CPB). The mean age was 18.00-75.00 (54.17±16.75) years. Amongst them, surgical resection was performed on arrested heart through median sternotomy in 11 cases, and robot-assisted surgery was performed on a beating heart in 1 case. Through retrospective analysis of the clinical data, the clinical characteristics, incidence, intraoperative technique, attachment site and short-term and middle-term surgical outcomes of right atrial myxomas were summarised.  Results  Right atrial myxomas comprised only 10.53% of all sporadic myxomas. The most common attachment site of right atrial myxomas was the atrial septum. All operations were successfully performed with no operative death or fatal postoperative complications such as low cardiac output syndrome, acute respiratory insufficiency, acute renal failure, stroke, malignant arrhythmia and pulmonary embolism. The operative time was 130-255 (180.25±40.53) min. The CPB time was 30-72 (49.17±14.33) min. The median aortic cross-clamping time was 20.00(18.00-42.00)min(range, 15-49 min). Nine patients (75.00%) were followed up for 12-109 (44.56±30.59) months. No deaths or recurrence occurred. The cardiac functions of all patients in the follow-up were class Ⅰ- Ⅱ (NYHA).  Conclusion  Right atrial myxoma is clinically rare. Once diagnosed, operation should be the first choice of treatment. The key to the success of the operation is the establishment of CPB and careful explorations to the cardiac chambers. The short-term and middle-term outcomes of surgical resection were satisfactory. However, long-term outcomes also need to be further observed.
