SUMMARY Echocardiographic studies were performed on six patients with autopsy-proved aortic atresia and hypoplastic left ventricle and two patients with surgically proved tricuspid atresia and hypoplastic right ventricle. The findings were compared to those from the echograms of 50 normal newborns who served as a control group. The ultrasound measurements obtained in the normal newborns were as...
There is no trustworthy estimate of the incidence of congenital heart disease as a whole, still less of tricuspid atresia. Doubtless many infants have died with tricuspid atresia, on whom no post-mortem examination was made, with merely a diagnosis of congenital heart disease or even unrelated diagnoses, since many of them succumb to infections such as pneumonia, meningitis, septicaemia. The fi...
There is still disagreement concerning the precise nature of the anterior ventricular chamber in "tricuspid atresia". Some argue that it is a right ventricle, while our own previous studies have suggested it is comparable to the outlet chamber seen in classical "single ventricle". We have compared the morphology of the anterior ventricular chambers in 48 examples of tricuspid atresia (absent ri...
holt-oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. they range from clinodactyly, absent or digitalised thumb, hypoplastic...
Three patients with normal hearts and no pulmonary abnormality had neonatal tricuspid regurgitation causing cardiorespiratory distress and cyanosis. The signs of tricuspid regurgitation resolved over a few weeks. In the acute phase echocardiography showed gross dilatation of the right atrium and ventricle. The interatrial septum bulged into the left atrium during the whole cardiac cycle. Dopple...
Thirty-one left ventricular (LV) biplane angiograms were performed in 28 patients with tricuspid atresia. Measurements of left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume were obtained by the modified Simpson's rule and systolic ejection fraction (EF) calculated. Left ventricular volumes and ejection fractions were also obtained in 19 control patients with ...
Clinical, angiographic and pathologic features are described in a 36-hour-old male infant with mixed (discordant) levocardia, aortic valve atresia, absent tricuspid (left atrioventricular) valve and resultant massive cardiomegaly. This is the first reported case of this type of complex in a heart with discordant chambers. A possible embryologic explanation is offered for the concomitant presenc...
AGENESIS of the tricu.spid valve may occur in two forms: (1) tricuspid atresia and (2) "tunguarded tricuspid orifice." In the latter, althouigh the normal orifice between the right atritum and right ventricle exists, there is no tricuspid valvtular tissue. The purpose of this report is to describe the clinical, radiologic, and pathologic findings of suich a case in which ptulmonary atresia coex...
