An echocardiographic pattern of normal tricuspid valve motion in a patient with tricuspid atresia, and pulmonic valve motion in a patient with transposition of the great vessels and pulmonary atresia were documented. The recordings of the valve motion resulted in an initial erroneous diagnosis. Although M-mode echocardiography is very useful for the initial diagnostic evaluation of critically i...
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...
Natural history of the ventricular septal defect in tricuspid atresia and its surgical implications.
We have previously reported isolated cases of anatomical and functional closure of ventricular septal defects in tricuspid atresia. To study this phenomenon further, clinical, angiographic, and pathological findings in 20 consecutive cases of tricuspid atresia were reviewed. Sixteen cases were found to have normally related great arteries (type I) and 4 had transposition (type II). In 6 of thes...
THE GENESIS OF COMMUNICATIONS between the right ventricle and coronary arteries commonly associated with pulmonary atresia remains uncertain. Edwards' attributed the persistence of these communicating sinusoids to increased right ventricular pressure and emphasized the importance of right ventricular outflow obstruction, intact ventricular septum, and competence of the tricuspid valve. Other au...
Congenital tricuspid atresia has been classified into two groups, those with and those without transposition of the great vessels (Kiihne, 1906). Each of these groups is further subdivided according to whether there is an increase or a decrease in the pulmonary blood flow (Edwards and Burchell, 1949). Tricuspid atresia with transposition of the great vessels and an increase in pulmonary blood f...
Doppler echocardiography was used to evaluate blood flow in the pulmonary artery in 14 patients 2 to 42 months (mean (SD) 17 (12) months) after a modified Fontan operation incorporating a direct atriopulmonary anastomosis. Preoperatively six patients had tricuspid atresia, six had a double inlet left ventricle, and two had pulmonary atresia with an intact ventricular septum. The postoperative r...
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 ...
