Conditions Treated with Pulmonary Root Translocation

Pulmonary root translocation is a complex biventricular reconstruction that is performed for the following conditions:

• D-TGA with pulmonary stenosis. Dextro-transposition of the great arteries (d-TGA) occurs when the two main arteries, the pulmonary artery and the aorta, are switched in position. Pulmonary stenosis complicates this condition because the blood vessel to the lungs is smaller than normal, and the standard repair cannot be performed.

• DORV with pulmonary stenosis. Double outlet right ventricle (DORV) is a rare congenital heart defect where the pulmonary artery and the aorta both come from the right side of the heart, or ventricle, rather than the aorta coming from the left ventricle. When there is pulmonary stenosis, an RV-PA conduit (artificial tube) is necessary in the repair and will require surgical replacement over time. A pulmonary root translocation instead of an RV-PA conduit avoids the need for future surgical conduit replacements.

• Congenitally corrected transposition of the great arteries (CCTGA) with pulmonary stenosis. CCTGA is a rare heart defect where the two heart ventricles are reversed, as are their roles, leaving the weaker right ventricle to pump blood to the body. When there is pulmonary stenosis, an RV-PA conduit (artificial tube) is often necessary in the repair and will require surgical replacement over time. A pulmonary root translocation instead of an RV-PA conduit avoids the need for future surgical conduit replacements.
