Asymptomatic pediatric pulmonic valve myxoma involving the right ventricular outflow tract: a case report and review of the literature.
Asymptomatic pediatric pulmonic valve myxoma involving the right ventricular out flow tract (RVOT) is very rare. The case is presented of 13-year-old asymptomatic boy who was referred to the cardiology clinic for evaluation of murmur, and was found to have a large mobile mass (3 x 2 cm) in the RVOT that protruded into the pulmonary artery across the pulmonary valve during systole, and relocated in the right ventricle in diastole. The patient underwent successful surgical excision of the tumor, which had a short stalk attached to the pulmonary valve. Macroscopic examination revealed a typical myxoma without any evidence of malignancy. This case elaborates the importance of early recognition and surgical excision of these tumors in order to prevent thromboembolic complications.
