[Persistent truncus arteriosus. Echocardiographic study of 8 cases].

Eight patients (4 male, 4 female) with persistent truncs arteriosus diagnosed by two-dimensional echocardiography are presented. Age ranged from 1 to 19 days. Diagnosis was based on the demonstration of a single vessel giving rise to the aorta, pulmonary arteries and coronary circulation. In 6 patients we were able to define the types of the truncus: in 4 patients corresponded to type I (with partial presence of aorto-pulmonary septum) and in 2 cases corresponded to type II (without existence of septum). All cases had a dilated truncus (1.13 +/- 0.06 cm, range 1.05-1.3 cm), with moderate overriding (52% range 30%-65%) and an infundibular ventricular septal defect (0.6 +/- 0.08 cm, range 0.45-0.85 cm). In 2 cases we could also demonstrate the presence of an interruption of the aortic aorta. We conclude that two-dimensional echocardiography (specially parasternal long-short axis views and subcostal for right or leftout flow tracts axis views) gives sufficient information about this cardiac malformation, which can be completed by the use of pulsed Doppler ultrasound.

[Radiological and angiocardiographical aspects of primary endocardial fibroelastosis in children (author's transl)].

In this article we try to show the value of radiography and angiocardiography in primary endocardial fibroelastosis. The 20 CASEs studied in this report, were angiocardiographically and/or necropsically proved. In spite of different opinions, we think that it is possible to reach an approximate diagnosis of this condition if we use the clinical and angiohemodinamic examinations. On the other hand, it is necessary to point out that pathology is characteristic. The most important radiological signs were cardiomegaly, together with venocapilar congestion, both of variable magnitude, and dependent on the degree of cardiac insufficiency. By means of angiocardiography we could appreciate a great dilatation and hypertrophy of the left ventricle and a reduction of the mobility and distensibility of this cavity along the cardiac cycle.

[Pulmonary atresia with intact i.v. septum (author's transl)].

Eight cases of pulmonary atresia with intact ventricular septum, are reviewed. Three corresponded to the group with small or hypoplastic right ventricle and five to the one with normal or enlarged right ventricular cavity. The electrocardiogram was of less value than plain chest radiography for the differential diagnosis of both groups. Cardiac catheterization revealed a right to left atrial shunt and the suprasystemic level of the right ventricular pressure. Selective angiocardiography demonstrates the stop of contrast at the level of pulmonary valve. Five patients were operated. An ascending aorta to right pulmonary artery anastomosis, Waterston type, was performed in three patients. Pulmonary valvotomy was carried out in the others.
