Abstract:
A left atrium thrombus, potentially a life-threatening complication, is an extremely rare in early infancy. Most cases are caused by mal-placement of central venous catheters or related to congenital heart diseases with left atrial blood congestion. Here we present an extremely low birth weight infant who developed a left atrial thrombus during the course of late onset circulatory dysfunction. The thrombus was successfully treated by recombinant tissue plasminogen activator. A hemodynamically unstable condition like late onset circulatory dysfunction should be taken into consideration as a potential risk condition of this rare disease.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
