How does Blalock-Taussig shunt work?
How does Blalock-Taussig shunt work?
The Blalock-Taussig (BT) shunt mimics the role of the ductus arteriosus, meaning it allows blood to flow from a major artery through a connection to the pulmonary artery. Not only does this allow more blood to be oxygenated by the lungs, it also encourages the pulmonary arteries to grow, making the next surgery easier.
Is Blalock-Taussig shunt open heart surgery?
This is a closed-heart procedure. The BT shunt mimics the role of the ductus arteriosus. It is often put in place after the ductus closes naturally.
What is a classic BT shunt?
A Blalock-Taussig shunt is a surgical procedure that helps improve oxygenation of the blood. It is used in cases of congenital heart defects that cause inadequate oxygenation of the blood (such as single ventricle or tricuspid atresia).
What is Sano procedure?
A Sano shunt is a shunt from the right ventricle to the pulmonary circulation. In contrast to a Blalock–Taussig shunt, circulation is primarily in systole. It is sometimes used as the first step in a Norwood procedure. This procedure was pioneered by the Japanese Cardiothoracic Surgeon, Shunji Sano (b. 1953) in 2003.
Is the Blalock-Taussig shunt still used?
The Blalock–Thomas-Taussig shunt is used in the first step of the three stage palliation (The Norwood Procedure)….

What is shunt surgery for heart?
A shunt moves blood from one area to another. This is done if the open-heart surgery needs to be delayed because the child is too sick to go through surgery. During a shunt procedure, the surgeon makes a surgical cut in the left side of the chest.
Is the Blalock Taussig shunt still used?
What are palliative shunts?
Palliative Blalock and Taussig Shunts (BT Shunt) is a surgery performed to connect the systemic artery (which carries oxygenated blood to the body from heart) with the pulmonary artery (the artery that carries deoxygenated blood from the right side of heart chamber to the lungs) in infants and children with inadequate …
What is modified Blalock Taussig shunt?
The modified Blalock–Taussig shunt is the palliative procedure most commonly used to augment pulmonary blood flow in single ventricle lesions with pulmonary outflow obstruction and cyanosis. A synthetic tube is placed from the brachiocephalic artery to the pulmonary artery.
What is Potts shunt?
A Potts shunt is a side-to-side connection from the left pulmonary artery to the descending aorta, thus diverting some of the high pressure pulmonary blood to escape out to the body without having to go through the damaged lungs.
What is a Norwood Sano?
The Sano Modification of the Norwood (diagram at right) involves the placement of a conduit (light blue) between the pulmonary artery and the right ventricle instead of the Modified Blalock-Taussig Shunt. Hypoplastic left heart is in the spectrum of single ventricle defects that has a sequence of staged repairs.
What is Glenn heart surgery?
The Glenn procedure is a type of open-heart surgery. The goals are to: Make blood from the upper part of the body (the head, neck, and arms) go directly to the lungs. This lets the blood pick up oxygen without passing through the heart. Take some of the extra work away from the right ventricle.
How does a Blalock Taussig shunt work?
Blalock-Taussig Shunt The first operation, a Blalock-Taussig shunt, creates a pathway for blood to reach the lungs. A connection is made between the first artery that branches off the aorta (called the right subclavian artery) and the right pulmonary artery.
What was Blalock Taussig role in Blue Baby surgery?
The 2004 HBO television movie Something the Lord Made, based on Washingtonian writer Katie McCabe’s 1989 article of the same name, was made about his role in the historic Blue Baby surgery, as was the 2003 public television documentary Partners of the Heart. Blalock Taussig Shunt – Left subclavian artery to left pulmonary artery.
When did Taussig approach Blalock and Thomas?
In 1943, having broached the possibility of a surgical solution to Robert Gross of Boston without success, Taussig approached Blalock and Thomas in their Hopkins laboratory in 1943.
What is the Blalock-Thomas procedure?
The procedure was developed by the two physicians together with Blalock’s laboratory technician Vivien Thomas. Taussig (cardiologist) observed that children with cyanotic heart defect and patent ductus arteriosus (PDA) live longer than those without PDA.
