Our doctors have access to, and experience with, the entire spectrum of specialized tools to repair heart defects during a catheterization.

  • Angioplasty balloons are used to open narrowed blood vessels.
  • Cutting balloons and ultra-high pressure balloons are specialized angioplasty balloons
  • Stents can be placed to keep narrowed blood vessels open.
  • Covered stents can be used to restore the integrity of torn or weakened vessels
  • Valved stents can be implanted to replace a non-functioning valve
  • Stainless steel and platinum coils can be used to block blood flowing through a misdirected vessel or a shunt that is no longer needed.
  • Several types of closure devices can seal a hole between heart chambers or in the heart wall.

Your child’s treatment team will choose the best option for your child's particular situation.

The future of pediatrics will be forged by thinking differently, breaking paradigms and joining together in a shared vision of tackling the toughest challenges before us.”
