Hyderabad, Dec 22: A team of doctors from Pediatric Cardiac Surgery Unit at KIMS Hospitals, Secunderabad gave a new lease of life to a baby from Zimbabwe by performing a complex cardiac surgery called Unifocalization.
The 11-month-old baby from Zimbabwe was brought to the hospital with a history of breathing difficulty and inability to feed properly. The weight of the baby was only 6.5 kg. On cardiac evaluation, the baby was found to have a very complex congenital cardiac problem called pulmonary atresia with MAPCAS (major aortopulmonary collaterals). This is a rare congenital heart defect that is found after birth. In this baby, the pulmonary artery from the right ventricle is absent leading to a condition called pulmonary atresia. Because of this, the branches of the pulmonary artery to the right and left lung are very small. Hence, there is no blood going from the heart to the lungs.
On the other hand, the lungs have been receiving blood in an abnormal fashion by vessels called MAPCAS which take origin directly from the aorta that is going behind the heart deep in the chest. There were four of them, two going to the right lung and two going to the left lung. This circulation is not normal and cannot be compatible with life. To restore normal circulation and to give a life to the baby, the doctors performed a very major and difficult operation called Unifocalization on December 3.
In this operation, the MAPCAS must be disconnected from the aorta that is behind the heart and connected to the small pulmonary artery that is coming from the heart. In other words, the routing of the blood to the lungs must be completely changed so that the blood goes from the heart to the lungs, a hospital statement here said on Sunday. Since the native pulmonary artery is small, it has to be enlarged and made big with a specialized patch material after connecting the MAPCAS. (UNI)
