Quizplus · Accepted Answer

The symptoms described in the scenario match those of Tetralogy of Fallot, which includes an overriding aorta, ventricular septal defect, pulmonary stenosis, and right ventricular hypertrophy. The cyanosis is due to deoxygenated blood from the right ventricle entering the aorta and being circulated throughout the body.
