Can someone with coarctation of the aorta get a body piercing or a tattoo?

Sure: You might be worried about an infection of a repaired coarct. I would speak with your heart doctor or surgeon before proceeding, because you may need antibiotics if there was another heart issue fixed at the same time (coarct is often linked to other problems). In most cases, you should be fine, though. A quick call is important before you do anything invasive.

Yes, It Depends.: Once a coarctation is repaired, surgically or by balloon dilation or stent placement the inside of the vessels grow and cover any foreign material (called endothelialization) once this has occured getting a tattoo or body piercing should be safe. However, an unrepaired coarctation with stenosis and turbulent flow has some risk for being a site where bacteria can land.

Yes... Carefully: Be careful and only go to a certified and approved site. People who have had cardiac surgery may be at increased risk for developing heart infections. Please discuss this with your doctor as they may recommend specific retailers that they know in your area.

Tattoo: Would not risk infection by getting a tattoo.
