The proposed technique will control the flow of blood in a shunt inserted as a replacement of artery between heart and the pulmonary artery in a new born's that will prevent excessive sudden blood flow so that new born baby can get an increased survival rate in the first surgical procedure in a congenital heart desease of Hypoplastic Right Heart Syndrome and Pulmonary Atresia.

Technique to provide solution for a congenital heart disease

The problem that we aim to solve via our invention is to help current issues with a newborn child diagnosed with a congenital heart disease Hypoplastic Right Heart Syndrome and Pulmonary Atresia. They are diagnosed with a single ventricular heart . As a result they have only one functional ventricle present and pulmonary blood flow will get reduced . Their right ventricle would pump the blood into the pulmonary artery and blood will reaching the aorta through a Patent Ductus Arteriosus (PDA). However as a normal process defined by mother nature the PDA is supposed to be closed within few days of birth as children are supposed to start using their own pulmonary artery. However, for these children doctors will keep the PDA open with an expensive injection until they could determine further medication process.

This defect isn't correctable, but some babies can be treated with a series of surgical procedure. In order to give the child more time to survive and gain weight and get ready for next stage of surgical procedure, the very first stage is to perform a life threatening high risk surgery where doctors will follow the Blalock -Taussig or BT-Shunt method. With this surgical procedure they implant a small shunt so that the blood is directed to the lungs through a Blalock-Taussig shunt.

This operations creates a connection between the veins returning low -oxygen (bluish) blood to the heart and the pulmonary artery. The goal is to allow the right ventricle to pump only oxygenated blood to the body and to prevent or reduce cyanosis so that the kid can survive and grow for the next stage of the operation.

Experienced doctors are successfully able to insert the shunt and immediate echo cardiogram shows that the shunt is functioning very well. However in next few hours most of these new borne kids die. They would die as the single ventricle heart is not able to handle the sudden increased volume of blood that flows in due to the insertion of this shunt. Their heart is not capable to pump out this increased volume of blood and as a result the child dies in cardiac arrest in next few hours.

The idea of our invention is to introduce a work around to this problem and we propose the...
