Cardiac myxoma with prenatal diagnosis

Neonatal Myxomas: Case Report and Literature Review

Myxomas are rare tumors in neonates and tend to have a different presentation compared to adults. We present an infant with a left atrial myxoma presenting with episodic tachycardia who underwent successful surgical excision. In addition, we performed a review of the literature, identifying 17 cases of neonatal myxomas. Unlike adults, neonatal myxomas are more common in males and occur more often on the right side of the heart. Constitutional symptoms such as fever or embolism are rare among neonates. Most patients have favorable outcomes following surgical excision, refuting earlier claims that neonatal myxomas are associated with poor outcomes.

Fetal cardiac tumors: clinical features, management and prognosis

Fetal cardiac tumors are rare and usually benign. While echocardiography is a reliable technique for diagnosing fetal cardiac tumors, their definitive diagnosis relies on pathological examination. The strategies used to manage fetal cardiac tumors are challenging. A good clinical result is their complete regression during pregnancy or shortly after birth, as often occurs with cardiac rhabdomyomas. Moreover, the fetal prognosis depends on the nature of the tumors, namely, their location, size, number and associated complications. The active treatment options for symptomatic fetuses depend on the fetal status and may include fetal open surgery, postnatal tumor resection with or without the bridge of intrauterine pericardiocentesis, and thoracoamniotic shunting. The ex utero intrapartum treatment procedure provides an alternative technique for performing fetal open surgery and has shown promising preliminary results in selected cases, but is invasive for both the mother and fetus.
