Timofei, two years old, was diagnosed with partial anomalous pulmonary venous drainage, where some of the pulmonary veins carrying blood from the lungs to the heart flow into other blood vessels or into the heart’s upper right chamber, instead of correctly entering the heart’s upper left chamber.
Timofei had an additional defect called Cor Triatiatum where an extra chamber inside the left collecting chamber can obstruct the return of blood from the lungs. He was operated in Voronezh.
