text: <unk>  is a rare cyanosis congenital heart disease with absence or discontinuation of a portion of the aortic<unk> . It is thought to be a result of faulty development of the aortic<unk>  system during the fifth to seventh week of fetal development. This condition leads oxygen-rich blood pumped out of the heart cannot reach the lower body and legs normally. Instead, the descending aorta is connected to the pulmonary artery by a blood vessel called the ductus arteriosus. The cause of<unk>  is thought to gene mutation. Usual signs and symptoms include rapid breathing, fast heart rate, weakness or fatigue, and poor feeding. Tests such as echocardiography and chest x-ray can show the enlarged right ventricle in patients. Treatments include medicines and surgery. The prognosis of<unk>  depends on the effect of surgery.
