Tricuspid insufficiency associated with severe left-sided valvular heart disease carries a poor prognosis. Twenty-two patients with severe pulmonary hypertension and tricuspid insufficiency underwent a tricuspid valvuloplasty in addition to left-sided single or double valve replacement. The tricuspid valvuloplasty was performed after weaning the patient from cardiopulmonary bypass. The efficacy of ...
Barber G - - 1988
Palliation of hypoplastic left-heart syndrome involves use of the morphologic right ventricle as the systemic ventricle and the tricuspid valve (in cases of mitral atresia/stenosis) or the common atrioventricular valve (in cases of malaligned atrioventricular canal) as the systemic atrioventricular valve. To determine the relationship between tricuspid or common atrioventricular ...

The clinical diagnosis of congenital left ventricular-right atrial (LV-RA) communication is difficult. Echocardiography appears to be a useful method in the diagnosis of this congenital cardiac defect. In previous reports authors have described M-mode echocardiographic findings of this anomaly. We present here two-dimensional echo findings in a patient with congenital ...
Knight W B - - 1988
A cyanosed neonate was diagnosed as having concordant atrioventricular connection and single cardiac outlet and aorta from right ventricle with atresia of the pulmonary valve. She underwent a systemic to pulmonary artery shunt and is now thriving. Additionally, the tricuspid valve was imperforate and a large ventricular septal defect caused ...
Veille J C - - 1988
Endocardial fibroelastosis is characterized by a porcelain-like thickening of the endocardium, resulting in a marked increase in echodensity of the endocardium, as well as ventricular dilatation and aortic atresia. With improvement in prenatal ultrasound, this condition can be suspected in utero on the basis of ventricular enlargement, poor ventricular contractility, ...
Walmsley R - - 1988
This study of the newborn child heart is based mainly on observations made on thin (0.2 mm) serial transverse sections of an entire thorax. Several features of the cardiovascular system associated with the fetal circulation are discussed. Despite considerable differences between the cardiac form in the newborn child and that ...

Waldman J D - - 1988
In three patients with complex cyanotic congenital heart disease, the conus was found to have no arterial outlet. The semilunar valves were at similar, caudad levels, and there was malposition of the great arteries. The aorta was related to the body--not the outflow portion--of the right ventricle in two patients ...
Leung M P - - 1988
Eight heart specimens were examined that had concordant connections of the cardiac segments and exhibited Ebstein's malformation. The displacement of the leaflets of the tricuspid valve from the atrioventricular junction varied from minimal and isolated involvement of the septal leaflet to involvement of the mural and anterosuperior leaflets as well. ...
Anderson R H - - 1987
Two congenitally malformed hearts are described, one studied in life and the other at autopsy, in which the topology of the ventricular mass was not as expected for the atrioventricular (AV) connection present. In Case 1, studied at autopsy, there was the usual atrial arrangement with a concordant AV connection. ...
Sharma S - - 1987
The veno-atrial connections, atrial morphology, atrioventricular (AV) junction, ventricular mass, ventriculoarterial (VA) connection and great arteries in 22 autopsied hearts, diagnosed as having bilateral left-sidedness because of the morphology of the atrial appendages, were studied. The findings were correlated with the arrangement of the thoracic-abdominal organs. A solitary spleen was ...
Ascuitto R J - - 1987
A 3-month-old infant is described in whom a persistent left superior vena cava impinged on the posterior wall of the left atrium, producing a subdivided left atrium with left-to-right shunting and congestive heart failure. To our knowledge, this anomaly has not previously been reported. The preoperative diagnosis, surgical management, and ...
