How is it treated?

It is a major heart anomaly that may require more than one procedure. The specialists at Medanta may employ the following surgical procedures:

..

  • Atrial septostomy

     This procedure enlarges the opening between the heart’s upper chambers to allow more blood flow.

  • Shunting

    Under this procedure a bypass or shunt is created from the main blood vessel leading out of the heart to the pulmonary artery, allowing adequate blood flow to the lungs.

  • Pulmonary artery band placement

     In this procedure, the surgeon may place a band around the pulmonary artery to reduce the flow of blood through it.

When do I contact the doctor?

The defect is diagnosed in the first complete examination of the baby. But, if you observe symptoms like breathlessness or discolouration, you need to seek medical help as early as possible to know the possible cause.
