Before Waylon could receive the heart surgery he so badly needed, his parents learned their surgeon was leaving the area. The Guidrys were suddenly faced with uprooting from their home in Fate, Texas (Rockwall County) and taking their very sick 6-month-old son out of town for surgery, most likely to either Houston or Chicago. Waylon was born at 27 weeks and 3 days with a rare heart condition called Tetralogy of Fallot, which creates obstruction to blood flow to the lung and is associated with a hole between the pumping chambers of the heart .

As they considered their options and prepared to pick up their lives, the phone rang one afternoon. It was Waylon’s cardiologist to tell them a new heart surgeon, Vinod Sebastian, M.D., would take on the case at Cook Children’s Medical Center in Fort Worth.

“Jordan and I didn’t know what to do,” Katie said. “We researched our options and we just couldn’t make up our minds. When we got the phone call, we were so relieved. Dr. Sebastian received all of Waylon’s history and was confident he could repair the Tetralogy of Fallot with one surgery and also spare his pulmonary valve, which traditionally has to be cut open and resected during this repair.”

The family arrived at Cook Children’s on Nov. 28, 2016 and Waylon underwent heart surgery on Dec. 14. Tetralogy of Fallot is a rare heart defect that occurs in about 5 out of every 100,000 babies.The surgery is a complicated one because the congenital heart disease results in four main congenital heart defects:

• Ventricular septal defect (VSD)
• Override of the aorta over the VSD
• Right ventricular outflow tract obstruction
• Right ventricular hypertrophy

ifelong monitoring is required due to the increased incidence of arrhythmia, exercise intolerance and reduced right ventricular function.

Often times when the surgery is performed, surgeons cut open and resect the pulmonary valve in the baby’s heart. If that happens, it usually means a heart surgery later in life to replace the valve. That was not the case for Waylon.

“As far as Waylon’s heart, his long-term prognosis is excellent,” Dr. Sebastian said. “Waylon is unlikely to need any further cardiac surgical intervention. In the past, Waylon’s condition was incurable. Even 10 years ago, the surgical repair routinely involved cutting open and resecting the pulmonary valve. His heart surgery is very gratifying because his heart problems are no longer an issue.”

Waylon and his family will face other non-cardiac health issues in the future, but for now the family feels very fortunate to have found Cook Children’s and Dr. Sebastian.

“He’s doing great now,” Katie said. “We are so grateful and blessed for having this opportunity to come to Cook Children’s and for our son to receive all the help he needs."

Waylon has been at  home now for more than two months and Katie is busy planning his 1 year old birthday party on May 30.

About Dr. Sebastian

Vinod Sebastian was born and raised in India and has pursued specialty training in the US in surgery, cardiothoracic surgery and pediatric cardiac surgery. During training he realized his passion of becoming a pediatric cardiac surgeon and the unique ability to provide life altering treatments to neonates, infants, children and adults with congenital heart disease.

He trained at Stanford University with Frank Hanley and VM Reddy in the field of pediatric cardiac surgery. During this time he trained in techniques of “single stage unifocalisation” and “extremely low birth weight cardiac surgery” at one of the largest practices in the world.

Dr. Sebastian is happy to be back in Texas at Cook Children's and providing pediatric cardiac surgery services in the Dallas/Fort Worth area.

Kenda Hooker was 3 years old when doctors discovered a hole in the top chamber of her heart. Like many congenital heart defect (CHD) patients, she went on with her life assuming her heart had been ‘fixed.’ As memories faded, her medical records were lost and her parents, who knew the most about her condition, passed away. So when she ended up with health problems nearly three decades later, doctors didn’t know where to begin.

“I started feeling dizzy and fatigued. I even passed out a few times,” said Kenda. “Several doctors told me the same thing, ‘You’re a new mom, you’re probably depressed. I even had my husband go with me to tell them that there was something wrong.”

Kenda wasn’t depressed. Instead, she was having issues with arrhythmia and would need a catheter ablation to remove the faulty electrical pathway inside her heart. That was just the first of several unfortunate diagnosis’s Kenda would hear over the coming years.

Next, it was the severe heart defect found in her first daughter, Koralyn.

“Koralyn Marie was born April 9, 2012. We knew prenatally that she had hypoplastic left heart syndrome,” said Kenda. “She spent her whole life at Cook Children’s, we were never able to take her home.”

Koralyn’s cardiologist, Lisa Roten, M.D., said her little heart was severely underdeveloped. As hard as they tried, there was little the doctors and nurses at Cook Children’s could do to save her. She passed away at 4 months old.

With the arrival of Kenda’s second daughter, Karis, in October of 2015 came more unwelcomed news. Another heart defect was diagnosed, again prenatally, but this one was less severe.

“Karis has an atrial septal defect,” said Kenda. “She had another hole in her heart but it has already closed on its own.”

Dr. Roten says there’s no way to know right now if there’s a genetic reason Kenda’s daughters both experienced heart problems. After all, she also has three heart-healthy boys.

“Kenda is part of the first generation of complex CHD patients who are truly thriving,’ said Dr. Roten. “A lot of the surgeries we perform now were not an option before the 1980’s so we’re seeing a new group of patients who have undergone surgery and are able to lead pretty normal lives.”

Dr. Roten says there are so many of these patients that a new subspecialty has even been created. At Cook Children’s, The Adult Congenital Heart Disease program treats patients who have outgrown pediatric care, including women with CHD who are considering becoming pregnant.

For Karis, her future is full of hope. Dr. Roten isn’t sure she will even need surgery. Even if she does, it likely won’t be an open heart operation like the one her mother had. Instead, her heart could be mended in the cardiac catheterization lab at Cook Children’s, with just an overnight stay. But like her mother, she will need to see a cardiologist for lifelong care.

“The fact that people with CHDs are going on to have kids shows just how far we have come,” said Dr. Roten. “At the end of the day, it may not be the life you would have chosen for yourself or your child, but it’s not a bad life. People with CHDs are going on to live good quality lives. The most important thing is to keep going.”
