Abstract:
We describe a case of a low birth weight neonate who presented on second day of life with progressive cyanosis and oxygen saturation of 60% by pulse oximetry. The echocardiography examination revealed a large tumor-like mass connected to the tricuspid valve, with severe obstruction of the right ventricular inflow and massive right-to-left shunt through the distended foramen ovale. A large vegetation-like lesion with calcifications was discovered intraoperatively and was debrided by shave excision technique under deep hypothermic circulatory arrest. Follow-up showed normal function of the tricuspid valve and preserved biventricular function.
