Which of the following is an indication for a Blalock-Taussig shunt?
BT shunts can be used to treat conditions such as pulmonary atresia, pulmonary stenosis, Tetralogy of Fallot, hypoplastic left heart syndrome and tricuspid atresia.
How long does a BT shunt last?
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.
What is modified Blalock-Taussig shunt?
(MBTS) Most often a modified Blalock-Taussig shunt (MBTS) is placed in the neonatal period to correct low oxygen saturation due to insufficient blood flow to the lungs, resulting from the new- born’s particular form of congenital heart disease.
Is a heart shunt serious?
Left-to-right shunts do not cause cyanosis at birth but can ultimately result in heart failure because of volume overload. The clinical significance of left-to-right shunts depends largely on their size and the volume of blood flow through them.
Is cardiac shunt normal?
Intracardiac shunts are abnormal pathways for blood flow in the heart that form either in addition to or in place of normal pathways for blood flow. They are the most common congenital heart defects.
What is the difference between the left and right pulmonary artery?
The right pulmonary artery supplies the right lung while the left pulmonary artery supplies the left lung. The left pulmonary artery passes anterior to the descending aorta and lies superior to the left mainstem bronchus.
How long can a shunt last?
Shunting is successful in reducing pressure in the brain in most people. VP shunts are likely to require replacement after several years, especially in small children. The average lifespan of an infant’s shunt is two years. Adults and children over the age of 2 may not need a shunt replacement for eight or more years.
