The electrocardiogram in tricuspid atresia and pulmonary atresia with intact ventricular septum.

چکیده
MOST PATIENTS with cyanotic congenital heart disease show right axis deviation and right ventricular hypertrophy of more or lesser degree in the electrocardiogram. Left axis deviation by contrast has long been recognized as the cornerstone of the diagnosis of tricuspid atresia.1 Although occasionally the A QRS is between 0° and +90° or may deviate slightly to the right in this condition, anatomic left ventricular hypertrophy is always noted at postmortem examination and the chest leads invariably indicate an adult R/S pro-

Prenatal Diagnosis of Pulmonary Atresia with Intact Ventricular Septum
Hypoplasia of the right ventricle is uncommon as an isolated entity. It may result from tricuspid atresia, but is most commonly secondary to pulmonary atresia with intact ventricular septum. Pulmonary atresia with intact ventricular septum is rare, accounting for 1-3% of cases of congenital heart disease. It occurs in 0.1 to 0.4 in 10,000 live births. Pulmonary atresia with intact ventricular s...
متن کاملEchocardiographic assessment of neonates with pulmonary atresia and intact ventricular septum.
In this prospective study, 27 consecutive neonates suspected to be suffering from pulmonary atresia and intact ventricular septum underwent detailed two-dimensional echocardiographic examination before cardiac catheterization. Of the 27 neonates 25 had pulmonary atresia and intact ventricular septum and the remaining 2 had "functional pulmonary atresia" secondary to severe Ebstein's anomaly of ...
متن کاملAn unusual case of congenitally unguarded tricuspid valve orifice associated with pulmonary valve atresia and intact ventricular septum.
We report on a premature neonate who presented with cyanosis soon after birth. She was found on echocardiography to have an unguarded tricuspid valve orifice associated with pulmonary valve atresia and an intact interventricular septum. Owing to the small-sized pulmonary arteries, she was initially managed conservatively with prostaglandin infusion, and at one year of age underwent a successful...
متن کاملComparison of the offset distance of the tricuspid septal leaflet in neonates with Ebstein's anomaly and neonates with pulmonary atresia with intact ventricular septum.
An indexed offset distance of the tricuspid septal leaflet ⩾8 mm/m2 is a quantitative criterion for the diagnosis of Ebstein's anomaly. The purpose of this study was to investigate the validity of this criterion for the discrimination of Ebstein's anomaly from pulmonary atresia with intact ventricular septum in neonatal patients. A total of 122 neonatal patients, 56 with Ebstein's anomaly and 6...
متن کاملTricuspid atresia: analysis of coronary artery distribution and ventricular morphology.
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...
