You might worry if you’re told your child has a heart murmur. But lots of kids are found to have heart murmurs at some point. And most won’t affect a child’s health at all. So What Is a Heart Murmur? The term “heart murmur” isn’t a diagnosis of an illness or disorder. The doctor might hear an extra sound in addition to the “lub-dub” we recognize as the heartbeat. A heart murmur is an abnormal sound (like a blowing or whooshing) that’s usually detected by a doctor who’s listening to the heart with a stethoscope during a routine examination. What’s an “Innocent” Heart Murmur? The most common type of heart murmur is an “innocent murmur” (also called a “benign” or “functional” murmur). This type of murmur is harmless. An innocent heart murmur is the sound of blood moving through a normal, healthy heart in a normal way. Just as you might hear air moving through an […]

Sudden cardiac arrest is nothing new, but it still gets plenty of attention when it affects a young athlete—usually because it’s so rare, unexpected and tragic. We’re all familiar with the stories of seemingly healthy teenagers collapsing on the field or court and succumbing to cardiac arrest. It’s estimated that between 6,000 and 8,000 young people experience sudden cardiac arrest (or SCA) each year, and only about one in 10 survive. The exact causes of SCA vary widely. Abnormalities in the heart or genetic conditions are often to blame, though there are times in which a definite cause is never found. In all cases, something causes the heart to unexpectedly beat out of control or stop beating altogether. Sudden cardiac arrest is so dangerous because it’s so hard to predict. But if the symptoms are recognized immediately, lives can be saved. Symptoms of SCA include: Collapse Lack of pulse No […]

When Jill’s third child, Emmy, was born with a hole in her heart, Jill wasn’t too worried. Her two older sons also had the condition—called Atrial Septal Defect (ASD)—and theirs had cleared up over time. In children with ASD, blood recirculates inside the heart, and doesn’t reach the rest of the body as well as it should. Dr. Mary Mehta, Pediatric Cardiologist at Nemours Children’s Specialty Care, Pensacola, worked with the family to track Emmy’s condition. It didn’t improve, and it soon became clear that Emmy would need complex and invasive surgery to repair the hole in her heart. When Emmy was just three years old, the right side of her heart began to enlarge, presenting more risks: asthma-like symptoms and other coronary issues.  It was time to prepare for open heart surgery. Emmy’s family met with Dr. Peter Wearden, Cardiothoracic Surgeon at the Nemours Cardiac Center at Nemours Children’s Hospital […]

February is Heart Month, a time when we traditionally hear many messages about adults at risk for heart disease. Now it’s time to focus this message toward kids, as medical research has shown that cardiovascular disease has its roots in childhood. According to the Centers for Disease Control and Prevention (CDC), one in five U.S. teens have abnormal cholesterol. This means either their good cholesterol (HDL) is too low or their bad cholesterol (LDL and triglycerides) is too high. As a parent, you may not be thinking about what cholesterol means for your kids. But with the dramatic increase in childhood obesity, more and more kids are at risk. Obesity can not only cause abnormal cholesterol, it can lead to increased risk of heart disease, diabetes, high blood pressure and stroke. So, here are four steps you can start taking — today — to help keep your kids’ hearts healthier […]
