When is BT shunt used?

By Liam Parker

BT shunts can be used to treat conditions such as pulmonary atresia, pulmonary stenosis, Tetralogy of Fallot, hypoplastic left heart syndrome and tricuspid atresia.

What is a central shunt?

A central shunt is an anastomosis between the ascending aorta and the main pulmonary artery made of PTFE. A central shunt uses a short PTFE connection between the ascending aorta and the main pulmonary artery.

What is BT shunt in TOF?

Blalock-Taussig shunt, also known as Blalock-Thomas-Taussig shunt, is a palliative procedure designed to increase pulmonary arterial blood flow in patients with right ventricular outflow tract obstruction (e.g. tetralogy of Fallot) or during initial staged repair of hypoplastic left heart syndrome.

Is BT 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. Shunts are usually used for four to five months, until the child outgrows them and a second operation or definitive repair is needed.

Is Blalock Taussig shunt open heart surgery?

Did Vivien Thomas go to medical school?

The life of Vivien Thomas is an inspiring story of an African-American pioneer who overcame the barriers imposed by a segregated society. With no formal medical training, he developed techniques and tools that would lead to today’s modern heart surgery.

What medical condition is Dr Blalock experimenting on?

At Vanderbilt, both Blalock and Thomas conducted experiments pulmonary hypertension and traumatic shock. Out of their research came the revelation that shock was associated with loss of fluid and a decrease in blood volume.

What does a BT shunt do for a child?

The high-pressure arterial system will force blood through the BT shunt to the lungs to pick up more oxygen. The shunt helps to return healthy color to a child whose skin, lips or fingernails may have appeared blue (cyanosis) because of low oxygen levels in the blood.

What is a Blalock-Taussig (BT) shunt?

What Is a Blalock-Taussig (BT) Shunt? A Blalock-Taussig (BT) shunt is a small tube, only a few millimeters wide, that is used to create a pathway for blood to go from the arterial circulation to the lungs. It is used to treat congenital heart defects that affect blood flow to the lungs.

What is the duration of a shunt procedure?

The shunt is inserted in a closed-heart procedure. Shunts are typically used for four to five months until definitive repair is required. Blalock-Taussig shunts, or BT shunts, are used for defects that affect the flow of blood from the right ventricle, through the pulmonary artery, and to the lungs.

How do you perform a bidirectional shunt?

The bidirectional shunt is performed by connecting the superior vena cava to the right branch of the pulmonary artery using fine sutures and by dividing or tying up the pulmonary artery (Fig. 5). It decreases volume load on the single ventricle while improving oxygen saturation.
