In cases of congenital heart defects with increased pulmonary blood flow, what symptom is commonly observed?

In congenital heart defects characterized by increased pulmonary blood flow, increased respiratory distress is a common symptom. This increased blood flow to the lungs often leads to pulmonary overcirculation, resulting in fluid accumulation and pulmonary congestion. As a result, the neonate may exhibit signs of respiratory distress, which can include tachypnea (an increased respiratory rate), retractions, and grunting.

The condition can also cause the lungs to become more prone to inflammation and potential respiratory infections, further aggravating the respiratory distress. Effective monitoring and prompt intervention are essential to manage this symptom and ensure adequate oxygenation for the affected infant.
