When a parent learns their child has been diagnosed with congenital heart valve disease, it can be terrifying. First, they want to know if their child will be alright, but as time goes by, they inevitably ask how or why, and then, what this means for their child’s future. Gaining as much information as possible and working with a great team of cardiologists can be the best solution to calming fears and answering the seemingly endless questions any parent has.

To help parents and patients learn more about congenital heart valve disease, Adam Pick met with Dr. Melita Viegas, a leading cardiac surgeon at the Guerin Family Congenital Heart Program at Cedars-Sinai Medical Center in Los Angeles, California. Dr. Viegas explained the top six facts that patients and their parents should know about congenital heart valve disease.

Key Facts About Congenital Heart Valve Disease

Here are the key insights shared by Dr. Viegas:

  • The disease is present at birth. “Congenital heart valve disease means that you were born with it,” said Dr. Viegas. “It’s something that happened when the baby was developing. So, it’s not something that anybody did or any type of medication. It was present at the time of birth.”

  • It is not a rare disease. “Another thing that people should know is that congenital heart disease is actually quite common. It occurs in 1 out of 100 births,” said Dr. Viegas.

Baby Tested for Congenital Heart Valve Disease with Stethoscope
  • Congenital heart disease doesn’t always require intervention. “Not everyone diagnosed with congenital heart disease will need an operation. Having congenital heart disease just means there is something abnormal; sometimes those things may not need an intervention, other times they do. For example, one percent of the population has a bicuspid aortic valve. Some people can live their entire lives without intervention, while others may need intervention later in life. So, congenital heart disease lives on a spectrum.”

  • Many patients don’t have any symptoms when they have congenital heart disease. “It is widely misunderstood, and often it’s because people don’t know they even have it. Symptoms can be non-existent and quite insidious.” Dr. Viegas explained that patients often find out they have congenital heart disease after having tests to diagnose other illnesses. “Certain exams that could pick these up could be chest x-rays, a CT scan, even when patients have no symptoms of the disease.”

Stress Test Evaluating Congenital Heart Valve Disease
  • The symptoms and progression of congenital heart valve disease can vary from patient to patient. “Not only is congenital heart disease misunderstood, but it can often progress and affect different systems within the heart for each patient. For example, one patient may have an irregular rhythm while another may have fluid around the heart.”

  • Advancements in cardiac medicine offers patients hope. “The good news is there are multiple interventions we can offer patients to help deal with their valve disease,” Dr. Viegas said. “It may be surgical or interventional, but we really look at the patient to decide what is best, depending on age, what the valve looks like, and several other characteristics of the disease. To ensure our patients live as normal a life as possible, long-term follow-up is extremely important. Our adult congenital cardiologists do an amazing job of following our patients to ensure they receive the care they need when they need it.”

Adam Pick: Hi everybody. It's Adam with HeartValveSurgery.com, and we're in Los Angeles, California at Cedar-Sinai Medical Center. I'm thrilled to be joined by Dr. Melita Viegas, who is a leading cardiac surgeon at the Guerin Family Congenital Heart Program here at Cedars. Dr. Viegas, it is great to see you again and thanks for being with me today.

Dr. Melita Viegas: Thank you so much, Adam.

Adam Pick: Yeah, so we have many patients and parents of patients who've been recently diagnosed with congenital heart valve disease. Mm-hmm. I'm really curious to know what are the top facts that all these folks in our community should know about congenital heart valve disease?

Dr. Melita Viegas: Number one, congenital heart valve disease means that you were born with it. It's something that happened when the baby was developing. So, it's not something that anybody did or any type of medication. It was present at the time of birth.

Another thing that people should know is that congenital heart disease is actually quite common. It happens in one out of a hundred births. That doesn't necessarily mean that everyone that is diagnosed with congenital heart disease needs an operation. It just means that there is something abnormal. Sometimes those things may fix it on their own or may not need an intervention, and then some of them do. For example, 1% of the population has a bicuspid aortic valve. Some people can go on to live their entire lives without having an intervention, and others later in life may need an intervention. Congenital heart disease lives on a spectrum.

Another thing that people should know is that congenital heart disease is widely misunderstood. Oftentimes it's because people don't expect that they even have it. Symptoms can be non-existent and quite insidious. and oftentimes it's out of the blue that something may happen or incidentally found when working up other illness these things are found. So, certain exams that could pick these up could be chest x-rays, or if for some reason a CT scan is done, we can find things that maybe aren't symptomatic in the patient at all.

Not only is congenital heart disease misunderstood, but it can often progress differently from patient to patient. it can affect different systems within the heart. For example, an irregular rhythm or fluid around the heart.

The good news is there have been many advancements in our field and there are multiple interventions that we can often offer patients, in order to deal with their valve disease. This may be surgical. It may be interventional, but really looking at the patient and deciding which is best, depending on age, what the valve looks like, and several other characteristics is very important.

To ensure that our patients live as normal of a life as possible, long-term follow-up is extremely important. Our adult congenital cardiologists do an amazing job of following our patients. And making sure that they get the care that they need when they need it.

Adam Pick: Dr. Viegas. Those are six wonderful tips for patients and parents who are managing congenital heart valve disease and on their behalf, on patients all over the world. Thanks to you for everything that you and your team are doing here at the Geurin Family Congenital Heart Program at Cedars. Thanks for being with me today.

Dr. Melita Viegas: Thanks, Adam.
