Assessment of atrioventricular septal defects by two dimensional echocardiography.

Smallhorn, J F, Tommasini, G, Anderson, R H, Macartney, F J

Ninety-six patients with an atrioventricular septal defect were assessed by two dimensional echocardiography. Forty-eight patients were judged as having two discrete valve orifices. In this group, 37...

Ventricular septal defects. Two dimensional echocardiographic and morphological correlations.

Sutherland, G R, Godman, M J, Smallhorn, J F, Guiterras, P, Anderson, R H, Hunter, S

To evaluate the ability of two dimensional echocardiography to identify and classify ventricular septal defects, 280 infants and children with clinically significant ventricular septal defects were...

Two dimensional echocardiographic assessment of communications between ascending aorta and pulmonary trunk or individual pulmonary arteries.

Smallhorn, J F, Anderson, R H, Macartney, F J

The value of two dimensional echocardiography in identifying communications between the ascending aorta and pulmonary trunk or individual pulmonary arteries was assessed in 24 children, all of whom...

Two dimensional echocardiographic diagnosis of situs.

Huhta, J C, Smallhorn, J F, Macartney, F J

At present there is no reliable method of recognising atrial isomerism by two dimensional echocardiography. We therefore used two dimensional echocardiography to examine 158 patients including 25...

Isolated anterior mitral cleft. Two dimensional echocardiographic assessment and differentiation from "clefts" associated with atrioventricular septal defect.

Smallhorn, J F, De Leval, M, Stark, J, Somerville, J, Taylor, J F, Anderson, R H, ...

Five patients with isolated clefts in the anterior leaflet of the mitral valve, unassociated with atrioventricular septal defects, are described. All had significant mitral regurgitation, with the...

Cross-sectional echocardiographic recognition of interruption of aortic arch between left carotid and subclavian arteries.

Smallhorn, J F, Anderson, R H, Macartney, F J

Interrupted aortic arch is a rare condition, usually lethal in early infancy without treatment. The only characteristic feature on conventional non-invasive investigation is peripheral pulse...

Suprasternal cross-sectional echocardiography in assessment of patient ducts arteriosus.

Smallhorn, J F, Huhta, J C, Anderson, R H, Macartney, F J

Ninety-four patients with patent ductus arteriosus, whose ages ranged from 28 weeks gestation to 8 years, were assessed by suprasternal cross-sectional echocardiography. A further group of 37 cases...

Cross-sectional echocardiographic assessment of conditions with atrioventricular valve leaflets attached to the atrial septum at the same level.

Smallhorn, J F, Sutherland, G R, Anderson, R H, Macartney, F J

Ninety two patients with both atrioventricular valves attached to the atrial septum, roofing a perimembranous inlet ventricular septal defect, were assessed by cross-sectional echocardiography. In...

Cross-sectional echocardiographic diagnosis of systemic venous return.

Huhta, J C, Smallhorn, J F, Macartney, F J, Anderson, R H, De Leval, M

To determine the sensitivity and specificity of cross-sectional echocardiography in diagnosing anomalous systemic venous return we used the technique in 800 consecutive children with congenital heart...

Morphological characterisation of ventricular septal defects associated with coarctation of aorta by cross-sectional echocardiography.

Smallhorn, J F, Anderson, R H, Macartney, F J

Cross-sectional echocardiograms of 18 neonates and infants with coarctation of the aorta and ventricular septal defect were retrospectively assessed. With a combination of subcostal and precordial...

Cross-sectional echocardiographic assessment of coarctation in the sick neonate and infant.

Smallhorn, J F, Huhta, J C, Adams, P A, Anderson, R H, Wilkinson, J L, Macartney, F J

To establish an integrated non-invasive method for diagnosing coarctation, cross-sectional echocardiographic appearances of 48 neonates and infants with coarctation were combined with clinical...

Two-dimensional echocardiographic assessment of common atrioventricular valves in univentricular hearts.

Smallhorn, J F, Tommasini, G, Macartney, F J

Twelve patients with univentricular heart and common atrioventricular valve were identified by two-dimensional echocardiography. Seven had an ostium primum atrial septal defect and five a common...

Detection and assessment of straddling and overriding atrioventricular valves by two dimensional echocardiography.

Smallhorn, J F, Tommasini, G, Macartney, F J

Sixteen patients with a straddling tricuspid and two with a straddling mitral valve were identified by two dimensional echocardiography. In all but one the atrioventricular valves appeared at the...

Assessment of total anomalous pulmonary venous connection by two-dimensional echocardiography.

Smallhorn, J F, Sutherland, G R, Tommasini, G, Hunter, S, Anderson, R H, Macartney, F J

Twenty-three patients with total anomalous pulmonary venous connection were studied by two-dimensional echocardiography. In all cases the diagnosis was made before invasive procedures, with surgical...

Abnormal cardiac signs after Fontan type of operation: indicators of residua and sequelae.

Leung, M P, Benson, L N, Smallhorn, J F, Williams, W G, Trusler, G A, Freedom, R M

Among 74 survivors of the Fontan type of operation abnormal cardiac signs were detected in 46 (62%) at postoperative examination. The findings were analysed in relation to the state of the...

Distinguishing between anomalous origin of the left coronary artery from the pulmonary trunk and dilated cardiomyopathy: role of echocardiographic measurement of the right coronary artery diameter.

Koike, K, Musewe, N N, Smallhorn, J F, Freedom, R M

Patients with anomalous origin of the left coronary artery from the pulmonary trunk usually have a large right coronary artery. This study examines the diagnostic value of measuring the diameter of...

Balloon dilatation of congenital aortic valve stenosis in infants and children: short term and intermediate results.

Vogel, M, Benson, L N, Burrows, P, Smallhorn, J F, Freedom, R M

Percutaneous balloon dilatation of the aortic valve was attempted in 25 consecutive patients with stenosis. The aortic valve diameters were normal for age. The balloon catheters were placed...
