Hyderabad: Heart surgeons from Krishna Institute of Medical Sciences (KIMS) have performed a complex cardiac procedure known as ‘Double Switch Operation’ on a 6-year-old girl from Sudan.
The young girl had a rare congenital heart disorder ‘Corrected transportation of great arteries’ in which the heart’s lower two chambers, the ventricles are in reverse positions. As a result, the major pumping chamber of the heart i.e. left ventricle is weak because it is pumping blood to lungs instead of the body.
To correct the disorder, the weaker left ventricle must be trained over a period to improve its strength so that it can pump blood to the entire body. After that, second stage of operation called Double Switch is performed.

According to pediatric cardiac surgeon in KIMS, Dr. Anil Kumar Dharmapuram, the young girl underwent the first stage of the operation a year ago called the Pulmonary Artery Band, which involves placing a circular constricting band in the pulmonary artery that is coming off from the left ventricle, making the left ventricle of the heart work against resistance and train it to be eligible for the second stage of the surgery.
After a year, the girl along with her parents came back for the second stage of the surgery. After a marathon surgery, the girl has recovered gradually and was recently discharged.
