The Nikaidoh procedure

The Nikaidoh procedure is an innovative aortic translocation operation for treating transposition of the great arteries when a VSD and pulmonary stenosis are present—a rare combination of defects. The procedure is performed at only at Boston Children’s and a handful of other specialty centers.

In this procedure, the aorta is switched, along with the aortic valve, and is placed in the pulmonary position — avoiding leaks of the abnormal pulmonary valve on the right side.

To follow our patients long term, Boston Children’s uses one of the only MRI scanners dedicated to pediatric cardiology. With our scanner, we can observe features like ventricular size and function, and we can look for the development of valve leakiness, obstruction of the great arteries or coronary artery obstruction.

We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
