Echocardiographic profile of infants of diabetic mothers.

Echocardiographic M-mode examinations were performed in 30 infants of diabetic mothers (IDM). Twelve of them had severe symptoms with hyperbilirubinemia, respiratory distress syndrome, septicemia and hypoglycemia in the neonatal period. The gestational age ranged from the 34th week to the 40th week, the birth weight ranging between 2280 g and 5820 g (mean 3455 g).

[Atrial septum defect: comparison of pre-and postsurgery echocardiographic data in adults and children].

Echocardiographic data in 13 adults and 17 children before and after surgical closure of an atrial septum defect are compared. Before surgery the enddiastolic dimension of the right ventricle was bigger in children than in adults. Septal motion was paradoxal or abnormal in 92% of adults and 65% of children (NS).

Value of M-mode echocardiography for non-invasive diagnosis of Ebstein's anomaly.

M-mode echocardiographic studies were performed in 11 patients, most of them adults, with Ebstein's anomaly of the tricuspid valve, proven by cardiac catheterisation. Simultaneous recordings of the tricuspid and mitral valves were obtained in all cases, the transducer position being outside the left midclavicular line in seven patients. Tricuspid valve closure followed mitral valve closure in all cases, with an interval ranging between 0.
