title: Transient neonatal cyanosis: unusual presentation of right-sided cardiac masses.
abstract: We report a case of a neonate with multiple cardiac masses, cyanosis, and a heart murmur. Arterial desaturation was the result of right-to-left shunting at the foramen ovale level caused by tricuspid regurgitation. Three right-sided cardiac masses were detected by echocardiography. By 2 weeks of age the patient had complete resolution of his cyanosis and improved tricuspid regurgitation following the normal decrease in pulmonary vascular resistance. At 2 years of age, he has no cardiovascular symptoms and the masses are calcified and have no hemodynamic consequences.
