Huge right ventricular myxoma in a 15-year-old female patient: a case report and literature review

Abstract Background Myxomas represent about 5–10% of primary cardiac tumors in children, and only 2.5–4% myxomas originate from ventricular chambers. Symptoms signs right depend mainly on the size site tumor its effect inflow outflow blood. Case presentation A 15-year-old female patient presented with syncope exertion symptoms congestive heart failure. She had a history dyspnea palpitation for 2 years before admission. Echocardiography magnetic resonance imaging (MRI) diagnose huge mobile mass (9 × 4.6 3.7 cm) prolapsing during systole into main pulmonary artery severe tricuspid regurgitation. The showed no contrast enhancement early dynamic delayed gadolinium images, suggestive thrombus. was safely excised annuloplasty repair done using atriotomy vertical ventriculotomy approaches. discharged well condition postoperative day 6. Pathologically, confirmed as myxoma old extensive hemorrhage inside. Conclusions Early echocardiography is essential patients complaining unexplained diagnosis management rare cases. Multimodality needed planning surgical procedure masses. Hemorrhage inside may lead to tumor.
