Surgical excision of a rare biatrial myxoma connected via the fossa ovalis resulted in complete removal and no recurrence over a 2-year follow-up period.
Case Report (n=1)
Biatrial myxoma is an extremely rare benign cardiac tumor that can be accurately diagnosed with echocardiography and successfully treated with surgical resection without recurrence.
RATIONALE: Myxoma is the most common type of primary benign cardiac tumor in adults. The left atrium is the most frequent site of origin followed by the right atrium. Biatrial myxoma is extremely rare. PATIENT CONCERNS: We present a case of a 60-year-old woman with biatrial myxoma, who presented with palpitations for one month. DIAGNOSES: Echocardiography revealed an irregular homogeneous mass in the left atrium and in the right atrium, and were connected via the fossa ovalis suspiciously. Computed tomography angiography revealed a hypo-intense mass in both atria. INTERVENTIONS: The tumors were successfully removed by surgical excision and histological analysis confirmed the diagnosis. OUTCOMES: The patient was discharged one week after surgery, and did not experience recurrence during the two years follow-up period. LESSONS: Biatrial myxoma is rare. Surgical resection is the mainstay of treatment and there is no recurrence reported. The clinical data and the features on echocardiogram of biatrial myxoma are reviewed, providing important clinical information for the pre-operative diagnosis and intraoperative removal of biatrial myxoma.
Li et al. (Mon,) conducted a case report in Biatrial myxoma (n=1). Surgical excision was evaluated on Tumor recurrence. Surgical excision of a rare biatrial myxoma connected via the fossa ovalis resulted in complete removal and no recurrence over a 2-year follow-up period.
