If the ventricular septal defect is smaller than the pulmonary valve, the surgeon will enlarge the defect. The surgeon then uses a patch, commonly made of bovine (cow) pericardium or the child's own tissue, to create a tunnel between the ventricular septal defect and the pulmonary valve. This allows for blood to flow from the left ventricle to ...
Ventricular septal defect is usually symptomless at birth. It usually manifests a few weeks after birth. [citation needed] VSD is an acyanotic congenital heart defect, aka a left-to-right shunt, so there are no signs of cyanosis in the early stage. However, an uncorrected VSD can increase pulmonary resistance leading to the reversal of the ...
Heart sounds of a ventricular septal defect patient. The condition consists of atresia affecting the pulmonary valve and a hypoplastic right ventricular outflow tract. The ventricular septal defect doesn't impede the in and outflowing of blood in the ventricular septum, which helps it form during fetal life. [3] [5]
At that time, the procedure was used for patients who had TGA with a ventricular septal defect (VSD). By the late 2000s, the procedure was employed in situations where the right ventricle is bigger than the left ventricle and the left ventricle connects to the pulmonary artery instead of the aorta ; examples include double inlet left ventricle ...
This gives the infant time to grow, increasing the size of, and thereby the ease of operation on, the heart, as well as the ease of recovery. Infants will generally require surgery within three to six months, however, they may be able to go up to two years before the operation becomes necessary, depending on the severity of the defect.

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] With proper care, most people who are affected live to be adults. [4]
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. [3]
This can be accomplished by a ventricular septal defect (VSD) connecting the left ventricle to the pulmonary artery or by a patent ductus arteriosus (PDA) connecting the aorta to the pulmonary artery. In the latter case, prostaglandin E1 is used to maintain the PDA connection until emergency corrective surgery can be completed.
