Final answer:
ASD is a neurodevelopmental disorder characterized by impaired social interaction and communication abilities. In ASD, there is a communication defect between the two atria of the heart, leading to abnormal blood flow patterns and increased pressure in the right side of the heart.
Step-by-step explanation:
Classification of ASD:
ASD is a neurodevelopmental disorder characterized by impaired social interaction and communication abilities. It is classified under the category of neurodevelopmental disorders along with other conditions like attention deficit hyperactivity disorder (ADHD).
Hemodynamic changes in ASD:
In ASD, there is a communication defect between the two atria of the heart, which leads to abnormal blood flow patterns. The opening between the atria, known as the atrial septal defect, allows oxygenated and deoxygenated blood to mix, causing an increase in blood volume in the right side of the heart and pulmonary circulation. This ultimately leads to increased pressure in the pulmonary artery and the right side of the heart.
