title: [Critical outflow valve obstruction under the age of one year (author's transl)].
abstract: This report represents the Brompton Hospital experience of infants and neonates with critical pulmonary valve stenosis and aortic valve stenosis. There were 25 patients with critical pulmonary valve stenosis and 8 with critical aortic valve stenosis. Critical pulmonary stenosis: Among the 25 patients up to one year of age, 11 were girls and the commonest presenting symptom was cyanosis seen in 15, the commonest physical sign being a systolic ejection murmur with a single 2nd sound. A more detailed analysis of the symptoms, signs and findings at special investigation will be presented. The evolution of a satisfactory technique of operation will be indicated in these critically ill patients, and the late follow-up will be presented. Critical aortic stenosis: There were 8 patients in this group all of whom were male. Dyspnoea was the commonest presenting symptom with a systolic ejection murmur and hepatomegaly as the commonest signs. All patients in this group underwent open aortic valvotomy and/or valvuloplasty with 3 deaths. A late follow-up of the survivors will be presented. In summary, a series of 33 patients up to the age of one year with critical obstruction of either the pulmonary or aortic valves will be presented. (his is one of the larger series to be reported in this age group.
