Double outlet left ventricle (DOLV) is a very rare birth defect in children. It occurs when the aorta and pulmonary artery both exit from the left ventricle. Symptoms of the condition can include a blue or purple tint to the skin, lips and nails; poor weight gain or appetite; rapid breathing/shortness of breath; sweating, especially during feeding; unresponsiveness and irregular fatigue.
The only way to confirm the condition is by echocardiography, magnetic resonance imaging (MRI), chest X-ray, and/or cardiac catheterization. Double outlet left ventricle is repaired through pediatric heart surgery.
