даже между аортой и легочной артерией.

Симптомы зависят от типа болезни сердца. Иногда дефект выявляется

при ходьбе или беге, отеки ног и отечность лица, а затем и всего

тело. Некоторые из этих аномалий могут быть хирургически исправлены

even between the aorta and pulmonary artery.

in walking or running, swelling of feet and puffiness of face, and later of the whole
