The incidence of univentricular heart malformations is estimated at 0.1 to 0.4 per 1,000 live births. [3] In the neonatal period, these patients depend on an aortopulmonary shunt that is maintained medically with prostaglandin and then surgically with an initial cardiac shunt procedure.
Atrial septal defect with left-to-right shunt. The left and right sides of the heart are named from a dorsal view, i.e., looking at the heart from the back or from the perspective of the person whose heart it is. There are four chambers in a heart: an atrium (upper) and a ventricle (lower) on both the left and right sides. [1]
The Fontan Kreutzer procedure is used in pediatric patients who possess only a single functional ventricle, either due to lack of a heart valve (e.g. tricuspid or mitral atresia), an abnormality of the pumping ability of the heart (e.g. hypoplastic left heart syndrome or hypoplastic right heart syndrome), or a complex congenital heart disease where a bi-ventricular repair is impossible or ...
The most common shunts are the Modified Blalock Taussig shunt (MBTS) or right ventricle- to pulmonary artery shunt (RVPA or Sano shunt). Most patients who undergo a Norwood procedure will proceed to further stages of single ventricle palliation. A second surgery, also known as the Glenn procedure, occurs at 4–6 months
Pulmonary Artery Banding (PAB) was introduced by Muller and Dammann in 1951 as a surgical technique to reduce excessive pulmonary blood flow in infants suffering from congenital heart defects. [1] PAB is a palliative operation as it does not correct the problems, but attempts to improve abnormal heart function, relieve symptoms and reduce high ...
By the time the first shunt was attempted on her, she was in danger of dying. Eileen Saxon's surgery was re-enacted in the documentary Partners of the Heart, produced by Spark Media, and broadcast on American Experience in 2003. [5] The 2004 movie produced by HBO, Something The Lord Made, is a dramatic feature based on the Saxon baby operation.
The timing of surgery depends on the baby's symptoms and size. [8] The procedure involves increasing the size of the pulmonary valve and pulmonary arteries and repairing the ventricular septal defect. [8] In babies who are too small, a temporary surgery may be done with plans for a second surgery when the baby is bigger. [8]
The Blalock–Thomas–Taussig shunt (BTT shunt), [1] previously known as the Blalock–Taussig Shunt (BT shunt), [2] is a surgical procedure used to increase blood flow to the lungs in some forms of congenital heart disease [3] such as pulmonary atresia and tetralogy of Fallot, which are common causes of blue baby syndrome.
