Around 75% of affected infants survive and are able to receive oxygen therapies and treatments to overcome this disease. In fatal cases, infants do not have noticeable or substantial respiratory recovery and can develop right-sided heart failure, ultimately leading to death. Patients that are not recovering will also continue to show signs of dyspnea, respiratory distress, and continued low body weight, heightening the risk of death. Infants that survive six months or longer have substantially better prognosis.
