In a rare case of common atrioventricular canal mimicking tricuspid atresia the clinical, radiographic, electrocardiographic, and M mode echocardiographic features were indistinguishable from those of classic tricuspid atresia. The cross sectional echocardiographic appearance and right atrial cineangiographic features were distinctive, however, and can be used to discriminate between this anoma...

The electrocardiograms from 28 unselected autopsied cases of tricuspid atresia, and eight autopsied cases of single ventricle were analysed: only those cases of single ventricle which showed left axis deviation were included. Electrocardiographic evidence of left ventricular preponderance in the precordial and unipolar limb leads was found in 27 of the 28 cases of tricuspid atresia, and three o...

Fourteen patients with double inlet left ventricle and nine patients with tricuspid atresia had biplane left ventricular angiography with simultaneous measurement of left ventricular pressure by micromanometer. Age distribution, haemodynamic function, and previous palliative operation were similar in the two groups. Left ventricular volumes were calculated frame by frame throughout the cardiac ...

We analyzed the flow velocity pattern in the main pulmonary artery after Fontan operation in patients with tricuspid atresia (n = 10) or with single ventricle (n = 10) by means of a catheter-mounted velocity probe. The area underneath the velocity signal of the forward flow was integrated, and ratios of the portions during atrial systole and during the diastolic phase to the total area (Fa and ...

We report the accurate prenatal diagnosis at 22 weeks gestation of right atrial isomerism in association with tricuspid atresia. Several distinctive sonographic features of isomerism of the right atrial appendages were present in this fetus: complex cardiac abnormality, ventriculoarterial discordance, juxtaposition of the aorta and the inferior vena cava to the right side, pulmonary atresia, an...

OBJECTIVE To compare the atrial and ventricular myoarchitecture in the normal heart and the heart with tricuspid atresia, and to investigate changes in the three dimensional arrangement of collagen fibrils. METHODS Blunt dissection and cell maceration with scanning electron microscopy were used to study the architecture of the atrial and ventricular musculature and the arrangement of collagen...

Left ventricular dimensions and contractility were determined by echocardiography in 33 patients with tricuspid atresia in 1985 and again in 1988. Eight patients remained palliated throughout the 3-year period; neither the left ventricular end-diastolic diameter (153±15% of normal vs. 157+19%o, p=NS) nor a load-independent index of contractility (rate-corrected velocity of shortening [VCFc]/end...

Five neonates with congenital tricuspid incompetence due to severe tethering of the tricuspid valve to the right ventricle by abnormal chordal and papillary muscle attachments are described. The abnormality was called tricuspid valvular dysplasia (TVD) if the basal insertion of the valve was normal and the Ebstein malformation if it was displaced into the sinus portion of the ventricle. In the ...
