Cardiac catheterization is a specialized procedure in which a long, flexible tube—a catheter—is inserted into a vein or artery and guided into the heart.

  • It’s often used instead of open-heart surgery to treat congenital heart defects.
  • Boston Children’s performs hundreds of cardiac catheterizations a year.
  • Boston Children’s trains more specialists in performing the procedure than any other hospital in the United States.

How Boston Children’s Hospital approaches cardiac catheterization

Boston Children’s interventional catheterization specialists us catheterization to observe a fetus or child’s heart structure, measure blood pressure, close holes, expand narrowed passages and open new passages. The procedure is now used in instances that once required surgery.

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.”
