that your baby has a congenital heart defect no longer means certain
heartbreak. Thanks to intricate surgeries and earlier diagnoses, most
tots with broken tickers don’t just survive: They thrive.
By Katie Sweeney
Jennifer ’84 and Steve Gates
had no reason to suspect anything was wrong with Ryan. He was a pink
and perfectly formed newborn, weighing in at a whopping 9 pounds.
Thrilled, they took him home to join big brother Connor, an active
For about a week everything was fine. Then
troubling signs began to surface. First there was Ryan’s breathing – it
seemed too fast. Concerned, Jennifer called the pediatrician.
It’s typical for newborns to have irregular breathing, the doctor reassured her.
Jennifer hung up the phone. He’s right, she told herself. I’m just overreacting.
But more problems followed. Ryan began to experience eating
difficulties. His weight was dropping. At three weeks, the pediatrician
made an ominous-sounding diagnosis: “failure to thrive.” The term is
commonly used to describe infants who aren’t gaining weight normally.
Jennifer and Steve took their son to a nearby hospital for a battery of
tests, including an echocardiogram – an ultrasound of the heart.
It soon became clear why Ryan was struggling. The baby who had looked
so healthy in the delivery room in fact suffered from a combination of
five serious heart defects – including hypoplastic right heart
syndrome, a condition where one side of the heart is severely
Steve and Jennifer were stunned. Congenital heart defects? How could
this be? No one in their families had ever had such a problem.
“I worried about everything during my pregnancy,” Jennifer recalls. “Except this.”
A generation ago, a baby born
with such a severe set of heart problems would have had a slim chance
of survival. But over the past quarter century, babies like Ryan have
been given a good chance not only to survive, but to live normal lives,
“In the ’60s and ’70s, many of the complex forms of heart
disease were fatal in infancy,” says Roberta Williams, chair of
pediatrics at the Keck School of Medicine of USC and vice president for
pediatrics and academic affairs at Childrens Hospital Los Angeles.
“Now, the vast majority are reaching adult life, and most of them are
While heart transplants are performed in some cases, they aren’t the
norm, due to both a dearth of available donor hearts and the potential
for organ rejection throughout the child’s life. Instead, surgical
advances and improved care have made it possible to repair an infant’s
own heart in the first days or weeks of life.
That’s good news, especially because congenital heart problems are the
most common birth defects, occurring in about eight of every 1,000 live
births. Many of those defects are relatively mild, but some, like
Ryan’s, are life-threatening.
In most cases, there’s no known cause for these defects, although
genetic errors are presumed to be at fault. But when you consider the
complexity of the heart’s development, it seems amazing that it ever
turns out right.
The fetal heart begins to beat about three weeks into gestation, making
it the first organ to function. Initially, it’s a tiny, pulsing tube.
Over the next three months that tube grows quickly, looping around and
folding on itself to create four chambers – two atria and two
ventricles – as well as four valves and the circulatory, coronary,
electrical and lymphatic systems. Throughout this intricate chain of
events, the heart sustains the fetus’s life.
If all goes well, the newborn baby will have a healthy heart. Usually
no bigger than a walnut, this tireless workhorse will pump blood
continuously through the circulatory system. The right ventricle will
send blood to the lungs for fresh oxygen, while the left ventricle will
move the oxygen-rich blood out to the body to nourish tissues and
organs. The valves will open and close to let blood flow in only one
Occasionally, though, something goes wrong during the heart’s
development, resulting in a defect. Defects can range from small
“holes” between the chambers of the heart to major malformations, such
as missing or underdeveloped chambers, or vessels attached to the wrong

“There’s a wide range of things that can happen to the development of
the heart and arteries during the embryology of a developing child,”
says Vaughn A. Starnes, chair of cardiothoracic surgery at the Keck
School and director of the Heart Institute at Childrens Hospital Los
According to Starnes, heart problems vary so
much that no two children will exhibit the exact same defect; nor is
there a standard surgery to correct them all. At the Heart Institute,
surgeons perform a constellation of 20 to 30 different procedures on a
routine basis, operating on more than 800 children a year.
Many of the operations are extraordinarily complex, requiring not just
skilled and experienced surgeons, but also a team of specially trained
nurses, physicians and therapists. For this reason, the delicate
surgeries are performed at specialized pediatric heart centers, such as
the Heart Institute at Childrens Hospital – one of the largest in the
The only times Steve Gates
had been inside a hospital were to witness the births of his two
children. But with Ryan’s diagnosis, he and Jennifer suddenly found
themselves practically living in one, straining to understand their
son’s condition and make life-or-death decisions about his treatment.
The first challenge: choosing a surgeon. Ryan would need a series of
three open-heart operations to repair his defects, they had learned.
And the first one should happen as soon as possible.
“When you have that type of experience with your child, it almost seems
like the world stops,” says Steve. “You don’t know where to turn.”
They got some advice from Jennifer’s brother, Randy Ryan ’87, MD ’92:
Go to Childrens and talk to Vaughn Starnes, he had urged. Both siblings
are USC alumni (as are their parents, Phyllis ’59 and David Ryan
’60) but Randy had the advantage of studying medicine at the Keck
School, so he knew all about Childrens Hospital Los Angeles.
It was the fall of 1995, and Starnes had arrived three years earlier,
lured away from Stanford University by the opportunity to restructure
the heart-lung program at USC University Hospital and create and head a
new Heart Institute at Childrens Hospital. In an April 1995 article, Los Angeles magazine had called him “the foremost pediatric cardiothoracic surgeon in the world.”
Steve and Jennifer had already interviewed one surgeon, and another was
on their list after Starnes. They had a deal: no decisions until
talking to all three.
But once in Starnes’ office, they forgot all about that. He was on the
cutting edge with surgical advances. He was honest and direct. And
there was no time to lose. Ryan’s health was quickly deteriorating; his
lips and skin had taken on a blue tinge from a lack of oxygen in his
They didn’t even have to discuss it.
“It was as if a stone had been lifted off our backs,” Steve recalls. “We knew Ryan was going to get the best of care.”
When one side of the heart is
underdeveloped, a baby is left with essentially a two-chambered heart
instead of a four-chambered one. Surgeons are unable to use tissue to
build two new chambers. Instead they reconstruct the heart to function
using the two working chambers it has.
takes place through a series of three open-heart surgeries. For
hypoplastic right heart syndrome, the first operation is performed
shortly after birth and is called the Blalock-Taussig Shunt. Surgeons
construct a synthetic tube, or shunt, and connect one end to the artery
going to the right arm and the other end to the pulmonary artery, which
goes to the right lung. This allows some of the blood going mainly to
the body to go to the lungs, where it can pick up more oxygen.
But that fix is only temporary. By the time the baby is 6 to 9 months
old, the shunt can no longer supply all the oxygen a baby needs to
grow. At that point, a second surgery redirects all the blood coming
from the upper body to the lungs. At age 2 or 3, a third and final
surgery is performed, redirecting the blood coming from the lower part
of the body to the lungs.
Today a baby has a greater than 90 percent chance of surviving all
three of these surgeries, Starnes says. Lifelong follow-up care will be
needed, and many will have to take heart medicines. Still, most will
lead fairly normal lives.
“We fully anticipate that they’ll be able to go to school, and their
physical activities will be pretty normal,” he explains. “They’re not
going to be competitive athletes. But they can certainly participate in
playground activities and things like playing soccer with their
Some heart defects can be corrected with just one surgery, such as when
a baby’s main arteries – the aorta and pulmonary artery – are connected
to the wrong chambers. (Ryan had this defect as well.) This means that
most of the blood returning from the heart to the body is pumped back
out without first going to the lungs to get oxygen. To correct this
defect, surgeons perform an arterial switch operation in the baby’s
first days of life, in effect “re-wiring,” or redirecting, the arteries
to the proper ventricles.
For still other problems, surgery is unnecessary. Minor defects often
resolve on their own, and others can now be corrected using
catheter-based interventions, says cardiothoracic surgeon Winfield
Wells of Childrens Hospital and the Keck School.
Just as adult hearts are repaired using catheters, a pediatric
cardiologist can guide tiny devices through catheters to various places
within the heart to open valves and close vessels and openings in the
Many procedures that used to require open-heart surgery are now
performed using catheters, Wells says, so children may enter and leave
the hospital in the same day.
No matter what the defect is, the goal is to repair it as early as
possible. In decades past, it was common for surgeons to perform only
palliative cardiac procedures on infants, and then perform the total
repair when the child was older. But that approach meant the baby’s
heart continued to develop abnormally.
“We think intervening earlier is better,” says Keck School pediatrician
Michael J. Silka, who is chief of cardiology at Childrens Hospital.
“For the first year of life, the heart has a lot of ability to adapt
Jennifer can’t remember how
long Ryan’s first surgery lasted: It seemed like forever. Finally,
Starnes emerged from the operating room. Ryan wasn’t out of the woods
yet, he had told them. The first 24 hours would be critical. But the
surgery had gone well.
Two weeks later, they brought their baby
home. Ryan was on so many medications that Jennifer had to create a
computer spreadsheet to keep track of them. By this time, he was nearly
2 months old and weighed just 5 pounds, 8 ounces. Nurses assured his
parents that Ryan would gain weight quickly.
They were right.
“It was like a miracle,” Jennifer says. “He just looked so much better after the surgery. It was incredible.”
Three months later, Ryan went back for the second surgery. This time,
he was in the hospital for only four days. With all his health
problems, Ryan was behind in his development. But with physical
therapy, he caught up by the time he was a year old.
At age 2, he was still doing great, progressing along the path of a
normal toddler. But soon it would be time for another operation – this
one riskier than the ones before.
“It was very hard to put him through surgery when he was looking so
great,” Jennifer says. “He seemed so healthy. But Dr. Starnes explained
to us that [his heart] would eventually wear out. He needed the third
surgery no matter how good he looked now.”
Two weeks after Ryan’s third and final surgery, he was back home. Once
again, Jennifer used a spreadsheet to track his medications. She was
exhausted from worry and lack of sleep. But for the first time in two
years, no operations loomed ahead. Ryan was OK.

Since 1995, the survival rates
for the hypoplastic right heart surgeries have improved about 10 to 15
percent, Starnes estimates. Survival rates for other surgical heart
repairs also have risen steadily, and in some cases dramatically, over
the past two decades.
For example, babies born with hypoplastic
left heart syndrome, a related and more difficult-to-repair condition
where the left side of the heart is underdeveloped, must also undergo a
series of three surgeries. Ten to 15 years ago, babies had only a 50
percent chance of surviving the first operation, the most serious.
Today, those chances are about 85 percent, Wells says.
There are several reasons behind the gains. Better surgical techniques
and materials play a role, although the surgery itself is just one part
of the equation. Also important are improvements in how to best care
for these babies before and after surgery, including better ways to
support their ventilation.
Congenital heart defects also are being diagnosed earlier – often
before birth. Since the heart develops early in pregnancy, problems can
be detected by the time the fetus reaches 18 to 22 weeks, and sometimes
as early as 10 to 14 weeks, says Keck School pediatrician Mark
Sklansky, who is director of fetal cardiology at Childrens Hospital.
If an obstetrician spots an abnormality in the fetal heart during a
routine pregnancy ultrasound exam, the mother is referred to a
specialist for a fetal echocardiogram. This targeted, high-resolution
ultrasound study provides a detailed picture of the fetal heart, so
specific defects can be identified, parents can be counseled and
appropriate delivery plans can be arranged.
Sklansky also is involved in research looking at 3-D and 4-D images of
the fetal heart. With this technology, a specialist can acquire a
complete volume of the fetal heart in just two seconds, interactively
visualize the heart from all viewpoints, including “surgeon’s eye”
views, and then continue to evaluate the fetal heart after the patient
has gone home.
Prenatal diagnosis helps parents emotionally prepare for having a
seriously ill baby and gives them time to evaluate options and make
important decisions about treatment.
It also prevents a baby with a serious heart defect from being sent
home after birth, as Ryan was. Ironically, many babies with severe
heart defects appear healthy at first. That’s because the heart’s
circulation is different in the womb, where the fetus gets its oxygen
from the mother’s placenta. The trouble often begins a few days after
birth, when a passageway between the left and right sides of the heart
closes, as it normally should in all infants. Once that happens, a baby
with a faulty heart will start to struggle.
But fetal screening isn’t perfect. “While more obstetricians are
looking closely at all aspects of the fetal heart during routine exams,
many defects continue to be missed or are nearly impossible to pick up
prenatally,” Sklansky says.
Three years after Ryan’s final surgery, a different kind of surprise came the Gates’ way: Jennifer was pregnant.
“We were ecstatic, but a little worried, too,” she says.
They had hesitated to have a third child, fearing that that baby, too,
might be born with a heart defect or other problem. Doctors had told
them the chances were slim, but it was still a risk.
If something was wrong, though, they wanted to be prepared for it.
Jennifer’s doctor referred her to a specialist for a fetal
echocardiogram. Everything looked good. “We knew it wasn’t a
guarantee,” Jennifer explains. “But it definitely calmed our fears.”
A few months later, their baby girl, Erin, was born. She was beautiful,
but they were taking no chances this time. Jennifer took her to a
pediatric cardiologist for a thorough checkup.
The exam confirmed they had nothing to worry about. Erin had a healthy heart.
and physicians have made huge leaps in treating congenital heart
disease, there’s still room for improvement. One problem that remains
is finding better heart valve substitutes for children.
Currently, when a child needs a new heart valve, surgeons insert one
made from donated human tissue. The problem is that the valve does not
grow with the child. So a child must endure major surgery every few
years to put in bigger replacement valves.
“If you put one of these valves in someone over age 60, it’ll last a
lifetime,” Wells explains. “Put that same valve in a 10-year-old, and
you have to replace it in two years.”
To solve this problem, researchers at Childrens Hospital and USC are
studying how to grow heart valves using the patient’s own cells. The
valve would then grow with the child and potentially last a lifetime.
Also, as an alternative to myriad invasive surgeries, researchers in
Europe have started to deliver heart valve replacements via catheters.
And there is ongoing research into the genetics of congenital heart
disease, with a few defects already linked to a particular chromosome.
“There’s probably a genetic marker for all of these defects,” Wells
speculates. “Somewhere in the code, there’s a typographical error, but
the relationships are complex. I think we will eventually find them,
but it’s going to be in the distant future.”

Ryan is now 10 years old.
Since his last surgery at age 2, he’s never looked back. Today, he’s a
healthy, outgoing fourth-grader and a good student. He likes golf and
tennis and riding his bike and skateboard. He’s in the Boy Scouts and
wants to go out for the volleyball team. His only medication? One
low-dose aspirin a day.
“When he runs, he’s not as fast as the
other kids,” Jennifer says. “But if you saw him playing on the
playground, you would never know the difference. You would never be
able to pick him out as the kid who had the heart problem.”
He doesn’t have specific restrictions, although doctors didn’t
recommend contact sports like football or wrestling. His brother
Connor, now 12, is a competitive swimmer, swimming 60 or more laps at a
time without stopping. Doctors don’t recommend that for Ryan. The
general guideline: He needs to take a break if he feels tired.
Intense team sports aren’t Ryan’s preference, anyway. His biggest love
is acting. He’s starred in school plays and occasionally auditions for
television commercials. He landed one national commercial last year.
One of the things everyone notices about Ryan? His happy, positive attitude.
“You kind of wonder, was that his nature at birth, and was that what
got him through the surgeries?” Jennifer says. “Or is it because in his
own way he’s so appreciative of what he’s been through?”
The family still lives in Tustin, and Erin is now 4. Jennifer is
actively involved in the local schools, and also volunteers to counsel
parents whose babies have been diagnosed prenatally with heart defects.
Steve occasionally talks to parents with her, and he has his own
financial services company.
The surgeries that Ryan went through are still too new for doctors to
predict outcomes spanning an entire lifetime. But his prognosis
continues to be good.
“We consider ourselves very lucky and blessed,” Jennifer says. “This
whole experience changed our thinking a bit. You learn to take life one
step at a time. You really appreciate each day for what you have.”
