Surgical excision of a 9.1 x 5.5cm left atrial myxoma during pregnancy successfully relieved severe mitral valve obstruction and allowed for a healthy full-term delivery.
41-year-old pregnant woman at 18+3/40 weeks' gestation with a massive left atrial myxoma
Intrapartum cardiac surgery (surgical excision of the mass)
Successful excision of the mass and delivery of a healthy baby
Surgical excision of a massive left atrial myxoma during pregnancy can be successfully performed with a multidisciplinary approach, resulting in favorable maternal and fetal outcomes.
Abstract Background Cardiac myxomas are rarely diagnosed in pregnancy. Case A 41-year-old 18+3/40 weeks’ gestation pregnant woman presented with dyspnoea and palpitations on a background of a benign pituitary microadenoma and previous tenosynovial giant cell tumour. Transthoracic echocardiogram demonstrated a 9.1 x 5.5cm left atrial mass attached to the fossa ovalis with moderate to severe obstruction to flow through the mitral valve. After multidisciplinary discussion regarding maternal and fetal risks, decision was made to proceed with intrapartum cardiac surgery given evidence of mitral inflow obstruction. The mass was successfully excised, and histology confirmed a cardiac myxoma. Post operative course was uncomplicated and a healthy baby girl was delivered at 39+1/40 weeks’ gestation. Discussion Diagnosis and management of myxomas can be challenging in pregnancy. Symptoms can be misinterpreted as being normal in the setting of physiological changes associated with pregnancy. Surgical excision is necessary to prevent complications including systemic embolization and haemodynamic deterioration. However, surgery is associated with significant maternal and fetal risks. Thus, a multidisciplinary approach to management is essential.
