What is pulmonary venous baffle?

Pulmonary venous pathway obstruction is a late complication of the atrial switch operation for transposition of the great arteries. Gaining peripheral access to the pulmonary venous baffle obstruction to treat the obstruction with stent deployment is difficult if not impossible.

What is a double switch heart surgery?

A double switch operation is used to correct congenitally corrected transposition of the great arteries (or L-TGA). In congenitally corrected transposition of the great arteries, both the ventricles (pumping chambers) and great vessels (aorta & pulmonary trunk) are transposed (on the opposite side).

What is a baffle in cardiac surgery?

A baffle is a surgically-created tunnel or wall within the heart or major blood vessels used to redirect the flow of blood. They are used in some types of heart abnormalities that a child is born with known as congenital heart defects.

What is baffle obstruction?

Baffle Obstruction: The baffles, that were created to switch the blood flow in the heart, are usually made from a synthetic material, called GorTex. With time, the baffles can scar which causes difficulty with blood flow (obstruction) in the heart.

What is D transposition of the great arteries?

Dextro-Transposition (pronounced DECKS-tro trans-poh-ZI-shun) of the Great Arteries or d-TGA is a birth defect of the heart in which the two main arteries carrying blood out of the heart – the main pulmonary artery and the aorta – are switched in position, or “transposed.”

Can transposition of the great arteries be fixed?

The most common type of surgery to correct transposition when identified in babies is the arterial switch operation. During this operation, the surgeon moves the great arteries so they are connected to the correct pumping chamber. The arteries that supply the heart (coronary arteries) must also be moved.

What is Senning repair?

The Senning repair is one of two “atrial switch” procedures used to functionally correct transposition of the great arteries (the other being the Mustard repair). The two repairs share a similar fundamental principle. Systemic blood flow is redirected away from the right ventricle and toward the left ventricle.

What is the mustard Senning procedure?

In a Senning procedure, the surgeon uses the patient’s own tissue to create the baffle. In the Mustard procedure, a synthetic material is used. Both are called “atrial switch procedures” because there is a baffle through the heart’s top part, or atria, which allows the blood to reach the ventricles.
