Left to right atrial shunting in tricuspid atresia.
In tricuspid atresia, an obligatory right to left shunt occurs at the atrial level. We have observed several patients with left to right interatrial shunts. Data from cardiac catheterisation in 40 consecutive patients were reviewed to determine the frequency and mechanism of left to right shunting in tricuspid atresia. An increase of 6% or more in oxygen saturation between the superior vena cav...
متن کاملFetal Heterotaxy with Tricuspid Atresia, Pulmonary Atresia, and Isomerism of the Right Atrial Appendages at 22 Weeks
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...
متن کاملFate of right ventricle to pulmonary artery conduits after complete repair of pulmonary atresia and major aortopulmonary collaterals.
BACKGROUND Surgical repair of pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals (PA/VSD/MAPCAs) requires insertion of a conduit from the right ventricle to the reconstructed pulmonary arteries. Although there is extensive literature on conduit longevity for many forms of congenital heart defects, there is currently limited information for PA/VSD/MAPCAs. It is...
متن کاملResults of systemic-to-pulmonary artery anastomosis for tricuspid atresia with reduced pulmonary blood flow.
Fifty-six patients with tricuspid atresia and decreased pulmonary blood flow received a systemic-to-pulmonary artery anastomosis as a preliminary operation. Thirty-five had a Waterston shunt, 12 a Blalock-Taussig anastomosis, and nine various other procedures. The age at operation ranged from 2 days to 10 years (median 4.5 months). Pulmonary atresia was present in eight newborn infants. Four pa...
متن کاملTricuspid Atresia with Increased Pulmonary Blood Flow
a finding not duly emphasized in previous reports. Comparison of the two groups revealed significant clinical and laboratory differences. Group II patients typically presented with severe congestive heart failure and expired within the first 2 months of life. Group I patients usually presented with mild congestive heart failure which responded to therapy. Five of the latter demonstrated progres...
