Endocardial Cushion Defect with Transposition of Great Vessels, Pulmonic Stenosis, and Multiple Anomalies

Endocardial Cushion Defect

THE REPAIR of atrial septal defects was first undertaken over a decade ago.1'Although secundum-type defects could be closed adequately without the use of cardiopulmonary bypass, it soon became apparent that defects of the endocardial cushion type were not am-enable to correction by indirect technies.5 Accordingly, the need arose to differentiate these two lesions; the clinical, electrocardiogra...

Multiple crystal echocardiographic evaluation of endocardial cushion defect.

A prototype multiple crystal echocardiographic system developed by Bom and associates was used to evaluate cross-sectional cardiac anatomy in real time in twenty infants and children with endocardial cushion defect (ECD). The findings were compared to fifty normal infants and children and nineteen patients with normal mitral valve anatomy but right ventricular enlargement (RVE). Three standard ...

Atrioventricular conduction in patients with incomplete endocardial cushion defect.

The cause of left axis deviation noted on the electrocardiogram (ECG) in patients with ostium primum atrial septal defect has been attributed to two differing mechanisms: left ventricular overload secondary to mitral insufficiency and a congenitally anomalous atrioventricular conduction system. In order to define the conduction characteristics of the atrioventricular conduction system in patien...

Transposition of the great vessels.

The vast majority of cases of transposition of the great vessels can be diagnosed in the first few weeks of life with electrocardiogram, x-ray and fluoroscope. The clinical pattern and the diagnostic features are described in detail. The degree of cyanosis, the characteristic heart shape and progressive increase in size coupled with generous hilar shadows all suggest this diagnosis. A new sugge...
