A rare cause of newborn central cyanosis

Pulmonary arteriovenous malformations are rare congenital vascular anomalies. They are usually associated with congenital hemorrhagic hemangioma. The hemodynamic effect of fistulas depends on their size, as well as the location. The most common manifestations include central cyanosis, ischemic stroke, murmur over the lung fields, cardiomegaly and, less often, heart failure. We present the case of a child who was admitted to the Department of Pediatric Cardiology and Congenital Heart Defects due to central cyanosis and heart murmur.
