The successful use of nitric oxide (NO) inhalation in a critically ill neonate with Ebstein's anomaly of the tricuspid valve is reported for the first time. This use of inhaled NO therapy suggests a therapeutic intervention that directly addresses the pathophysiologic process of severe neonatal Ebstein's anomaly.

Three patients with patent ductus arteriosus and moderate aortic stenosis had a marked reduction in aortic valve gradient following transcatheter ductal occlusion. The hemodynamic effects of an aortopulmonary shunt on the severity of left ventricular outflow obstruction and the implications on intervention are discussed.

Abstract. Kingella kingaeis a fastidious Gram-negative rod that since the 1980s has been appreciated as a cause of a variety of human infections, including bone and joint infections, bacteremia, and rarely endocarditis [2, 6, 7, 9]. K. kingaeendocarditis is rare, and only a few cases occur in normal, native valves. We report a case of K. kingaeendocarditis in a patient with hair–cartilage hypoplasia who had previously undergone bone marrow transplantation. The combination of these rare conditions is discussed.
