Acyanotic heart defects are congenital heart conditions that do not significantly reduce the amount of oxygen in the blood. These defects often involve structural issues in the heart, such as ventricular septal defects or atrial septal defects, which allow blood to flow abnormally but still maintain adequate oxygen levels. Symptoms may include fatigue, difficulty breathing, and poor growth in infants. These conditions are typically diagnosed through echocardiograms or chest X-rays and can often be managed with medication or surgery. Early detection and treatment are crucial to prevent complications and ensure a better quality of life for affected individuals.
