Primary cardiac tumors in children: a center's experience

Background: Cardiac tumors which may induce sudden death are rare entities with an autopsy frequency of 0.001-0.030 %. This study aims to analyze the characteristics and outcome of pediatric patients with primary cardiac tumors treated in our center. Methods: Sixteen patients with primary cardiac tumors treated at our center between January 2000 and December 2014 were included into this retrospective review. The patients' age ranged from 1 day to 13 years (mean age, 46 months), with weight ranging from 3.2 to 45 kg (mean weight 17.5 kg). All patients were diagnosed by echocardiography, magnetic resonance imaging and computed tomography. Results: We did complete resection of the mass in 15 patients with cardiopulmonary bypass (CPB), whereas partial resection was done in one patient. Fifteen children recovered well, and one patient died of low cardiac output syndrome at 5 days after operation. Rhabdomyoma was the most frequent tumor type, followed by myxoma, fibroma, hemangioma; No malignant tumors were found. Conclusions: Echocardiography has provided consistent assessment of anatomy and function. Complete surgical resection is valuable treatment for cardiac mass when detected even in asymptomatic patients. Rhabdomyoma is the most frequent tumor type, followed by myxoma and fibroma.
