As the pressure in the lungs increases in the child with PA, the right ventricle hypertrophies and will eventually fail. Manifestations of right-sided failure include peripheral edema. Lung manifestations are seen in left-sided heart failure. Tachycardia is nonspecific. Although both sides of the heart can eventually fail, the first signs and symptoms will be of right-sided failure.
