A case of congenitally-corrected transposition of the great arteries is presented with the correlation of thallium scintigraphic results with catheterization data. The essential features of the thallium scintigrams were marked counterclockwise rotation of the heart with perfusion abnormalities of the inferior wall and apex. Since patients with congenitally-corrected transposition of the great a...

T7 °a ASSESS a patient with complete transposition of the great arteries (TGA) for corrective surgery,1 it is necessary to have accurate and complete physiologic data. Measurement of pressure and oxygen saturation in the pulmonary artery is essential in many cases. Difficulty in catheterization of the pulmonary artery in transposition of the great arteries has led to the development of several ...

Transposition of the great arteries or TGA is a potentially fatal congenital heart malformation where the pulmonary artery and the aorta are switched. The switch means that the aorta, which normally carries oxygenated blood, carries deoxygenated blood. There are two types of the malformation, d-TGA where no oxygen reaches the body and l-TGA where some oxygenated blood circulates. In the US, the...

OBJECTIVES To describe the various surgical options, perioperative management strategies, and outcomes for this complex lesion. DATA SOURCE MEDLINE and PubMed. CONCLUSIONS L-transposition of the great arteries is a relatively rare defect, comprising less than 1% of all congenital heart defects. There is considerable heterogeneity in clinical presentation depending on the presence of associa...

It has long been doubted whether or not it is possible for a transposed aorta to arise from a morphologically left ventricle, and for a transposed pulmonary artery to originate from a morphologically right ventricle, this having been designated anatomically corrected transposition by Harris and Farber in 1939. Such cases have been regarded as errors in observation (Lochte, 1898), as inexplicabl...
