Abstract
BACKGROUND: Myxoma is an uncommon disease and its symptoms vary greatly depending on size, location and mobility. Right-sided myxoma, especially right ventricular myxoma, is much rarer, and the symptoms are alien and uncharacteristic. The lack of understandings poses challenges to prompt diagnosis and timely treatment. CASE PRESENTATION: A 44-year-old female patient was diagnosed with giant right ventricular tumor. Right heart failure and systemic congestion caused by right ventricular outflow tract obstruction were observed on this case. Surgery was performed to excise the mass which was measured at 9.5 * 5.0 cm and confirmed as myxoma pathologically. CONCLUSIONS: Right-side myxoma is easy to be unnoticed due to its low incident rate and atypical symptoms. Delay in surgical intervention might cause unrecoverable complications. More comprehensive understanding of the symptoms is expected to help improving the diagnose and treat of right-sided myxoma.
