Surgical treatment of rare benign right ventricular tumors in infants: two case reports

Objective: To describe rare clinical and morphological forms of right ventricular neoplasms (mesenchymal hamartoma, rhabdomyoma) in infants which required surgical treatment in infancy.Methods: We performed 2 radical operations to remove right ventricular neoplasms: neonatal mesenchymal hamartoma and infantile rhabdomyoma.Results: We confirmed the effectiveness of surgery for rhabdomyoma and mesenchymal hamartoma in infants based on an 11-year postoperative follow-up period. We followed a necessary search strategy to detect tuberous sclerosis complex often associated with rhabdomyoma.Conclusion: Surgical treatment of rare right ventricular neoplasms in infants demonstrated favorable long-term results.
