Acyanotic cardiac lesions with normal pulmonary blood flow

This article, the second in a series discussing acyanotic cardiac defects, examines acyanotic cardiac defects with normal pulmonary blood flow: pulmonary stenosis, peripheral pulmonary stenosis, coarctation of the aorta, and valvular aortic stenosis. A similar defect, interrupted aortic arch, is also discussed. The hemodynamics, clinical presentation, differential diagnosis, surgical repair, and medical management of each defect are presented. Parental teaching needs are identified and discussed.
