Sixteen cases of peripheral pulmonary stenosis have been studied clinically and by cardiac catheterization. Diagnosis has been proved in all cases by manometric measurements and/or cineangiocardiography. All patients except two were below 2 years of age. Ten cases were of type I, i.e. the stenosis was localized to the pulmonary trunk or its main branches. Six patients were of type III, i.e. they had diffuse stenosis of the pulmonary arterial tree. The physical findings, which in many cases are typical and include the presence of a systolic murmur over both lung fields, should alert the physician to the diagnosis at the bedside. At cardiac catheterization the configuration of the pressure tracing in the main pulmonary artery is typical, showing an abrupt rise and fall of the systolic wave followed by a low situated dicrotic notch. There is no doubt that in the past many cases of peripheral pulmonary stenosis have been wrongly diagnosed as "essential pulmonary hypertension".

Standardization of cardiopulmonary roentgenograms in infants and children.

Methods were devised to standardize cardiopulmonary radiographs of infants and children. With these techniques, films can be taken either at the end of inspiration and in systole, or at the end of inspiration alone. A statistical evaluation of these two methods demonstrated their superiority over the usual procedure. The use of these techniques is strongly recommended in patients of the pediatric age group.

[Heart surgery in newborn infants and in early infancy].

During the past five years, 127 newborn infants with marked anoxia, severe cardiac failure or respiratory problems secondary to a cardiac lesion were operated upon at l'Hôpital Ste-Justine, Montreal, Quebec.Infants in cardiorespiratory distress from a cardiac lesion for which the surgical treatment is well established, such as complicated coarctation of the aorta, were either cured or improved in 78% of cases. The fatal outcome following medical treatment of patients suffering from lesions for which the surgical treatment is not yet well established, e.g. interruption of the aortic arch, led us to operate upon these infants with the hope of salvaging some of them despite the high surgical risk.The decision to operate was usually based on clinical grounds; however, cine-angiocardiography was at times required to establish the exact diagnosis. Light anesthesia was essential to the success of the operation. Postoperative care was facilitated by a team of nurses well experienced in the treatment of newborn subjects with heart lesions. Fluids were administered in a minimum quantity of 700 c.c./m.(2) for 24 hours, and potassium was the only electrolyte added to the replacement fluids. Respiratory problems were reduced to a minimum by active physiotherapy. However, intubation with aspiration of tracheobronchial secretions was carried out when necessary.
