Fifteen-year experience in the surgical management of right atrial myxoma (original) (raw)
2017, Cardiothoracic and Vascular Sciences
Objective: This study presents our experience with the clinical presentation, tumor characteristics, surgical management and post-operative outcomes of patients operated for right atrial myxoma. Methods: A retrospective analysis of all patients diagnosed with right atrial myxoma in our center from years 2000 to 2015 was conducted. All data were gathered from medical records following board approval. Twelve cases were identified, eight of which were female. Data is reported as frequencies, percentages, averages and ranges. Results: Clinical presentation proved very heterogeneous amongst our group. The most common finding was right-sided heart failure in 2 patients (17%). The average tumor size was 30mm and the most common attachment site was the inter-atrial septum. Myxomas were resected through median sternotomy or right thoracotomy. Post-operative morbidity includes dysrhythmias and tricuspid disease despite morphologically normal tricuspid structure in most cases. There was no perioperative mortality. Follow-up averaged 39 months and showed no recurrence. Conclusions: While surgical results for right atrial myxoma are satisfactory, its inconsistent presentation and rarity continue to pose a diagnostic challenge to clinicians who encounter it. Our data and review of literature identified right-sided heart failure, tricuspid regurgitation and pulmonary embolism as common findings in right atrial myxoma and lead us to suggest that clinicians consider it in their differential diagnosis in situations where such findings go unexplained.
