Approximately 90% of primary paediatric cardiac tumours are benign lesions. Depending on their location and size, benign cardiac tumours may cause inflow and outflow obstructions, cyanosis, valvular insufficiencies, myocardial ischaemia, associated dysfunction, systemic embolisation, arrhythmias, and even sudden death. Decision-making and timing for surgery can be challenging in children. Herein, we present an asymptomatic 11-year-old girl with papillary fibroelastoma in the mitral, tricuspid, and pulmonary valves, discussing the decision-making process and successful surgical management.
