Every year, approximately 2,000 seemingly healthy people under the age of 25 die from sudden cardiac arrest (SCA), a tragic statistic that Cook Children's Health Care System is working to change.

In recognition of National Sudden Cardiac Arrest Awareness Month this October, Cook Children's is highlighting its year-round commitment to ensure schools and communities are prepared for such a medical emergency through its Project ADAM program, which provides life-saving training and resources.

Sudden Cardiac Arrest occurs when the heart stops beating, which leads to loss of breath or irregular breathing and prevents blood flow to the brain and other vital organs.

“With the proper training, anyone can do CPR and use an AED, and with enough of us trained and empowered to do so, we have the ability to potentially save someone’s life,” said Sarah Thieroff, Project Adam Program Coordinator.

Project ADAM (Automated Defibrillators in Adam's Memory) is a program named after 17-year-old Adam Lemel. In 1999, while playing high school basketball, Lemel collapsed and went into Sudden Cardiac Arrest. His family learned that he could have been saved with the right preparation and equipment. An automated external defibrillator (AED) was not available. His parents helped start the Project ADAM program at the Children’s Hospital of Wisconsin in his memory. Cook Children’s was the first in Texas and is now one of 52 hospitals and program sites to provide free cardiac resources, including training and AED devices. 

Thieroff recalled the motivating force behind the program's founding: "What we learned now is that Adam could have had a chance. I was faced with a choice. I couldn't save my son, but maybe I can save yours," Adam's father said.

More than 780 schools and 28 school districts are recognized to be Heart Safe. A designated Heart Safe school and district have completed a quality AED training program that includes a CPR/AED trained emergency team, an emergency plan for their AED and required AED drills.

“Knowledge of what to do, and muscle memory from practicing the appropriate steps may correspond to earlier action and in turn lead to a more successful outcome,” said Danielle Moyé, M.D., at Cook Children’s Heart Center.

Beginning the 2026-2027 school year under Senate Bill 865, also known as the Landon Payton Act, public and private schools will be required to implement a cardiac emergency response plan, mandate CPR and AED certification for specific school employees and volunteers, and require drills to test their emergency response.

“With the SB 865 bill, we have legislative support to encourage schools to act now and prepare,” said Dr. Moyé. “And we are ready to help them. We are here and happy to walk through what this looks like and ease some of the burden from the school’s administration, nursing team, and district.”

An AED is supported by the FDA to detect ventricular fibrillation. It has been designed and tested in both children and adults. Cardiac arrest is reversible in most victims if it is treated within a few minutes with an electric shock to the heart to restore a normal heartbeat. This process is called defibrillation. A shock delivered by an AED within 3-5 minutes can save a life and for every minute that passes, survival rates drop by 10%.

Through the Cook Children’s Project ADAM program, anyone can be trained. The program provides schools across Texas with the necessary tools and education to plan and develop their public access defibrillation (PAD) program.

“The expectation is that schools will be prepared for if it happens, not just putting it off or waiting to establish an emergency team, plan and/or drill if/when it happens,” explained Thieroff.

Signs and Symptoms of Sudden Cardiac Arrest

• Not breathing or irregular breathing (i.e. agonal gasps)
• Unresponsive and/or sometimes there are “seizure-like” movements.
• If someone witnesses a collapse:
  • Check for responsiveness.
  • Tap/lightly shake the person and ask if they’re okay, then if they’re not responsive, call for help/have someone call 911 immediately
  • Send someone to get the AED. If they’re unsure where the AED is, when they call 911, the 911 dispatcher should tell them the location of the nearest registered AED in the area.

Cook Children’s provides free Hands Only CPR/AED training, cardiac emergency response planning, and AED drill assistance to any school in Texas.

Liam lived from March 25 to Nov. 1, 2013, and spent much of his brief life at Cook Children’s with critical issues ranging from an operation to repair his intestines, to heart problems, to feeding concerns.

He seemed to be constantly fighting until it was too much for his little body to overcome.

Now a little over a year later, Vickie Phathaphone, Liam’s mother, looks back on her time at Cook Children’s with an emotion that may be surprising to some – gratitude.

Recently, Phathaphone reached out to Cook Children’s Facebook page. She wanted to thank the staff who treated her little boy.

“My family and I, including Liam, loved the medical staff at Cook Children’s and you guys gave us the most amazing experience and educated us well,” Phathaphone said. “The staff at Cook Children’s helped my family and me by teaching us how to not be afraid to hold our little Liam.”

Phathaphone said doctors and nurses updated her family every day and Cook Children’s updated her by cellphone as needed. She said the NICU nurses taught her so much, ranging from the importance of breast milk and how to pump it, to how to carefully bathe, feed and hold her fragile baby.

“Although being a parent is natural, with Liam’s condition it was quite frightening,” Phathaphone said. “We did not want to hurt him, but we were reassured by the nurses what not to do and what to do. I loved how the staff treated Liam, as he was a part of their family, and I am thankful that Liam was under such amazing care.”

After letting a group of the physicians know about the letter, they were appreciative of Phathaphone’s kind gesture and began to reflect on the loss of not only Liam, but other children who have died too soon.

Surgeons Vincent Tam, M.D., James Miller, M.D., and Lisa Roten, M.D., a cardiologist, share with us what their life is like after the loss of a child.

Dr.Tam

He tries to stay in control as he fights back the tears.

But on this day, as hard as he tries, Vincent Tam, M.D., a pediatric heart surgeon at Cook Children’s, struggles to keep his composure. He’s thinking about Liam.

Dr. Tam performed two heart operations on Liam. All the procedures were successful, but other underlying problems were simply too much for the baby, who was born premature, to overcome.

In practice for 23 years, Dr. Tam copes with the death of a patient by compartmentalizing the loss. He tries his best not to dwell on it, so it won’t impact his performance in the operating room or his role as husband and father. Then, every once in a while, he receives a note or hears from a parent whose child has died, like the one from Phathaphone. The parents don’t want to express grief or even anger, but simply to say thanks.

“It’s hard because if somebody dies or somebody has a bad complication, I think, ‘Oh gosh, could I have done something differently?” Dr. Tam trails off and after a long pause continues to speak. “There’s all kinds of questions that you can ask as a Monday morning quarterback, but personally I’ve dealt with it in a way that I feel like I’ve … um …”

Again, a long pause as he composes himself. “I do the best I can with every surgery and that’s all I can do.”

Dr. Miller

Shortly after Liam’s birth, James P. Miller, M.D., a pediatric surgeon at Cook Children’s, operated on him to repair gastroschisis, a condition where the baby is born with the intestines on the outside of the body.

Even after 17,000 surgeries and 27 years as a surgeon, it only takes a quick glance at a child’s chart for the memories to come flooding back. He remembers Liam and his mom. He says he knew from being around her for a short period of time and the love and compassion she always showed to her child, Phathaphone would be a great mom.

Dr. Miller has gotten to know some patient families well over the years. Throughout his career, he’s been to many of their weddings, but he’s also seen death.

“It can devastate you for weeks,” Dr. Miller said. “It can be like reopening a wound when you realize it’s the first anniversary of a child’s death. You hope you have somebody in the hospital that you have helped or made a difference in their lives, just to get out of your rut. I don’t think people realize how much doctors do feel. When you do what we do with these kids, you do get attached to them.”

Dr. Roten

For the patient families who are cared for by Lisa Roten, M.D., a cardiologist who specializes in fetal echocardiography at Cook Children’s, they see someone who cares deeply for her patient families. But they also may be surprised to know that she understands Dr. Tam’s need for compartmentalization.

“The truth is, you have to do that,” she said. “You wouldn’t be a physician if you couldn’t do that. We have a work life and we have a personal life. I can’t carry that home with me. I do talk about the loss of my kids, but with the people who can empathize with me. I talk to my colleagues and staff, the other doctors and nurses, who cared for the child.”

Still, Dr. Roten admits to developing a special bond with most of her families and says a gesture like the one from Phathaphone and other parents means a lot to her. As much as the families sometimes need closure by writing a note or speaking to the doctors, Dr. Roten also needs to find a way to say thank you to the parents for entrusting their child’s care to her and goodbye to the children.

Dr. Roten makes every effort to reach out to families who have had a child pass and to go to the funerals whenever possible. It allows her to complete the circle of care.

“At the end of the day, we’re all humans. We are people who have families and we are touched by these families we see,” Dr. Roten said. “Even after the child dies, they never really leave our lives. There are ways that we continue on together. We take our cues from the family. If they ever want to reach out or touch base with us, that’s comforting to us. It is the end of a relationship that sometimes you’ve had for years and years with families and sometimes like in Liam’s case, it’s been shorter.

“But they are all so special to us.”
