Pediatric Cardiac Catheterization

Cardiac catheterization is a non-surgical procedure. It can be used to diagnose a heart defect like coronary artery disease, heart valve disease, congenital heart disease and cardiomyopathy. It can also be used to fix a heart defect by placing a closure device, replacing a valve or widening an artery or vein with a stent. More recently, our doctors have started performing lymphatics interventions in the catheterization lab for patients with lymphatic abnormalities. Doctors may also use cardiac catheterization to evaluate a previously repaired heart defect to make sure everything is as healthy as possible.

At Children’s Health℠, we are constantly finding ways to raise the bar on care. For example, we were one of the first centers in Texas with a dedicated patent ductus arteriosus occlusion program that focuses only on fixing holes/abnormal connections in the hearts of babies weighing less than two pounds. We also participate in national research aimed at improving cardiac catheterization outcomes. Medical device companies actively seek our expertise to test new technology and equipment. Our team publishes reports and studies in major medical journals and is invited to speak at medical meetings and conferences across the U.S.

Typically, before your child has a cardiac catheterization, they will have an echocardiogram. This is a painless, one-hour test that makes images of your child’s heart. This helps us prepare for your child’s cardiac catheterization by showing how their heart is structured and how the blood flows through it. Occasionally the team may perform advanced imaging including CT scan and MRI for better planning of the procedure.

There are a few risks associated with cardiac catheterization, but these are uncommon, and our team’s experience helps us keep them to an absolute minimum. Risks include:

• Pain
• Bleeding
• Infection
• Risk from anesthesia
• Abnormal heart rhythms

Our interventional cardiologists, cardiac anesthesiologists, nurses and other experts work together to make all cardiac catheterization procedures go as smoothly as possible.

What to expect before a Pediatric Cardiac Catheterization

Our cardiac scheduling team will call you to give you a date for your child’s procedure. If needed, we’ll do a pre-catheterization consultation beforehand to talk to you and your child about the procedure. A cardiac nurse will call you the day before the procedure to go over instructions for your child's anesthesia, like what medications are OK to take, and when your child should stop eating and drinking. Having an empty stomach before the procedure helps prevent your child from vomiting during the procedure and possibly breathing food or liquid into their lungs.

Each of our three, state-of-the-art cardiac laboratories has the most advanced equipment and features the lowest levels of radiation available. The laboratories are designed so our team can perform each procedure in a streamlined way to reduce the amount of anesthesia a child is given.

What to expect during a Pediatric Cardiac Catheterization

During a cardiac catheterization procedure, a small, thin tube (known as a catheter) is inserted into veins and arteries to reach the heart. Cardiac catheterization uses X-rays to create images of the heart. Often, a dye is injected through a catheter that has been placed in the heart or major blood vessels. Additionally, measurements of pressures and oxygen levels within the heart chambers, veins and arteries are taken to assess the function of the heart and lungs.

Pre-procedure activity is usually scheduled between 6 a.m. and 10 a.m. The first procedure of the day usually starts between 7:30 am and 8:30 am. First, you’ll meet with a nurse and anesthesiologist who will answer your questions. Then, we’ll move your child to the catheterization lab. You’ll be escorted to the waiting area. Each hour, our team will text you updates on how your child is doing. After the procedure is over, we’ll print pictures of your child’s heart so you can see what we found or what we were able to fix.

What to expect after a Pediatric Cardiac Catheterization

Your child will be in a recovery room for a few hours until the anesthesia wears off. We’ll continue to monitor their heart rate, oxygen level, breathing rate and blood pressure while they recover. During this time, they’ll be able to drink clear fluids and eat. They shouldn’t feel any pain. Most children can go home either the same or the next day.
