Surgical Excellence in Pediatric Cardiac Care
Recently, a patient story titled “Chenoah and Katie’s Challenging Journey: Overcoming Hypoplastic Left Heart Syndrome” highlighted the journey of a mother facing a high-risk pregnancy after an early diagnosis of a serious congenital heart condition, Hypoplastic Left Heart Syndrome (HLHS)—a rare defect affecting approximately 1 in 3,955newbornsintheUnitedStates.

Overcoming the Odds: Azrael’s Fight Against Hypoplastic Left Heart Syndrome
A story of resilience, precision, and life-saving care
Recently featured on OUHealth.com, Azrael’s journey highlights the realities of navigating Hypoplastic Left Heart Syndrome (HLHS)—a complex congenital conditionrequiringhighlyspecializedsurgicalcarefrom theearliestdaysoflife.
“The lady came up to me after church and said, ‘Your son said something strange,’” Tiara shared. “She had asked them about feeling the presence of God, and he said, ‘I have. When the doctor was fixing my heart, Jesus was there. Dr. Burkhart fixed my heart and Jesus helped him.’”
From the very beginning, Azrael’s care required a coordinated, multidisciplinary approach—bringing togethersurgicalexpertise,criticalcare,andlong-term planningtosupportthebestpossibleoutcome.
AtOklahomaChildren’sHospitalOUHealth,thatlevelof care is led by experts like Harold Burkhart, Pediatric CardiothoracicSurgeonandDivisionChiefofCardiac, Thoracic and Vascular Surgery, who performed Azrael’s firstlife-savingprocedureatjustsevendaysold.
“His heart is doing so well for his condition,” his mother, Tiara, shared. “I know some patients who are in their 30s and 40s who haven’t had to have transplants and are still going strong. I think Azrael will be one of those.” “We love OU Health—it’s truly been amazing.”
The impact of this experience has been profound—so much so that Tiara, already a nurse, is returning to the OUCollegeofNursingtofurtherhereducation,inspired bythecareherfamilyreceived.
Azrael’s story reflects more than a single procedure—it represents the strength of a system built around collaboration, innovation, and a commitment to deliveringadvanced,high-acuitycareforeventhemost complexpediatricconditions.

Faith, Medicine, and Miracles: Angel’s Journey of Survival at OU Health
When 24-year-old Angel Arevalo arrived at OU Health with his heart functioning at just 5% capacity,hisconditionrapidlyescalatedintocardiacarrest—requiringimmediate,life-saving intervention.
Under the leadership of advanced heart failure and transplant cardiologist Mohit Pahuja, a multidisciplinary“shockteam”wasactivatedtostabilizeAngelduringoneofthemostcritical moments of his care. The team brought together specialists across cardiology, critical care, andsurgery,includingcardiothoracicsurgeonShinobuItagaki
As Angel’s condition deteriorated, Dr. Pahuja and the team made the decision to initiate extracorporeal membrane oxygenation (ECMO)—a highly advanced therapy used to temporarily take over heart and lung function. Dr. Itagaki played a key procedural role in implementing this life-sustaining support, helping stabilize circulation and giving Angel a chanceatrecoverywhensurvivalseemedunlikely.
“We knew that he couldn’t survive for much longer… He was so young — we had to give him a chance.”
Despite multi-organ failure and a prolonged period without responsiveness, the care team remainedsteadfast—managingacomplexdiagnosiswhilecloselymonitoringforanysignsof recovery.
In a powerful moment that underscores both the clinical and human sides of care, Angel’s first neurologicalresponsecameunexpectedly:
“As she continued to pray, I suddenly stood up… this was the first sign of brain activity that showed the doctors I was recovering.”
After nine days on ECMO and weeks of intensive treatment,Angelregainedconsciousness.Withintwo and a half weeks, he was discharged home with improvingheartfunctionandarenewedoutlook.
“I am so grateful for the team — they worked so hard to keep me alive.”

Spring Break Safety: What Our Trauma Team
Wants Every Family to Know
InOUHealth’sspringsafetyarticle,Dr.JasonLees,Robert D. Gordon, Jr. Professor of Surgery and Section Chief of Acute Care Surgery at the University of Oklahoma College of Medicine, reinforces a critical message: prevention remainsthefirstlineofdefense.
“Whenitcomestopools,eyesonkidsatalltimesiscritical,” he notes, emphasizing constant supervision during water activities.
Seasonal trends also bring predictable risks. “ATVs are probably our biggest source of injuries as the weather warmsup,” Dr.Leesexplains,pointingtotheimportanceof protectivegearandsafeoperation.
Atthesametime,heremindsusthatpreparationextends beyond prevention. “Would you live in a city that didn't have a fire department or police department?” he asks— highlighting the critical role trauma systems play in every community.
“Our multidisciplinary teams ensure that we can handle all ranges of trauma care,” he adds, reinforcing the strength andreadinessofOUHealth’ssurgicalteams.
In moments of crisis, access to the highest level of trauma care can mean the difference between life and death. As highlighted in “Oklahoma’s Lifeline:WhyLevelITraumaCentersMatter,”OUHealthservesasacritical resource for patients across the state, delivering comprehensive, aroundthe-clockcareforthemostsevereinjuries.
“For the most critically injured patients, access to the highest level of care can determine survival.”
OUHealth’straumaprogramoperates24/7,ensuringthatsurgeonslikeDr. Cross are always available to deliver immediate, life-saving intervention. Supported by a full spectrum of specialists, advanced technology, and dedicated trauma teams, this level of care represents the gold standard in emergencymedicine.
“It’s not just about being available—it’s about being prepared at every level.”
In 2024 alone, more than 9,000 Oklahomans required treatment for lifethreatening trauma—ranging from motor vehicle accidents to catastrophic falls. For these patients, timely access to a Level I Trauma Center significantly impacts survival and recovery—making the expertise of surgeonslikeDr.Crossessentialtooutcomesacrossthestate.
What distinguishes a Level I Trauma Center is not just capability, but consistency.Thesecentersmustmeetrigorousnationalstandardssetbythe American College of Surgeons, including continuous re-verification every threeyearsandadherencetomorethan120performancecriteria.

Through leadership, clinical excellence, and a commitment to patient outcomes, Dr. Cross and the trauma team continue to serve as a vital resource for communities across Oklahoma—advancing trauma care not justfortoday’spatients,butforfuturegenerations.
In An Accident That Nearly Took Everything: Care Excellence With OU Health’s Level I Trauma Center, OU Health highlights the life-saving impact of rapid, coordinated trauma care—where every second counts and every team member plays a critical role.
AtthecenterofthisstoryisDr.CeliaBlair,atraumasurgeonwhoseworkreflectsthe precision,urgency,andleadershiprequiredinthemostcriticalmomentsofpatient care. Her perspective underscores what truly defines a Level I Trauma Center: not justavailability,butreadinessateverylevel.
“We have short response times to help ensure that all of our patients are getting appropriatelytreatedinthat‘goldenhour.’”
ForDr.Blairandthetraumateam,the“goldenhour”ismorethanaconcept—itisa standard of care. From the moment a patient arrives, highly trained specialists mobilize immediately, delivering rapid assessment and intervention designed to maximizesurvivalandrecovery.

Our department continues to lead in advancing transplant science through innovation and collaboration.
Dr. Paulo Martins and Dr. Narendra Battula, in collaboration with the University of Florida, received patent approval for a novel technology focused on improving kidney transplant outcomes.Thismilestonerepresentsasignificant achievement in our ongoing research and developmentefforts.
The patented innovation centers on the quantification of soluble DNA in hypothermic machine perfusion perfusate as a reliable method for assessing kidney transplant quality and predicting post-transplant outcomes. This approach has the potential to enhance clinical decision-making and improve patient outcomes by providing more precise, data-driven evaluationsoforganviability.
This work highlights our department’s commitmenttotranslatingcutting-edgeresearch into meaningful clinical advancements and reinforces our role as a leader in transplant innovation.
