High Tech, All Heart

“It looks like something out of Star Trek!” That’s what visitors have been saying as they tour the control room of the new CHOC Children’s Cardiac Catheterization Laboratories, which open next month. And yes, our state-of-the-art facilities are quite impressive. In fact, the CHOC Heart Institute is one of the few pediatric facilities in Southern California equipped with completely brand-new, state-of-the-art, pediatric-focused medical technology.

CHOC Children’s treats virtually all forms of congenital and acquired heart disease, from before birth through adolescence. Our pediatric cardiologists are pioneering catheter-based techniques that replace conventional open-heart surgery for some complex disorders. What’s happening at CHOC is far more exciting than science fiction.

Congenital heart disorders occur in about nine of every 1,000 newborns. Of these, 25 percent will require invasive treatment within the first year of life. CHOC pediatric cardiologists perform 400 interventional procedures each year with outcomes exceeding the national average for quality and safety.

Many heart conditions that formerly required open-heart surgery may now be treated using less-invasive, catheter-based techniques. The CHOC Children’s Heart Institute features two cardiac catheterization labs, including a “hybrid” lab that may incorporate aspects of conventional surgery, as needed. Each cardiac catheterization lab is equipped with the most advanced medical imaging technology available:

• Toshiba Infinix-i biplane cardiac catheterization system, providing multiple views of the heart while reducing radiation exposure to the patient.
• Philips iE33 3-D echocardiography, for noninvasive 3-D images of the heart.
• 1.5 and 3.0 TESLA 3-D magnetic resonance (MR) and computed tomographic (CT) angiography, showing blood flow within arteries and veins around the heart and lungs.

And if one picture is worth a thousand words, how about 16 clear images displayed on a 65-inch, medical-grade, LED screen? Our cardiology team will be able to view any diagnostic image, plus other vital information live from a patient’s electronic medical record while performing procedures.

New “Home” For All CHOC Heart Services
Opening in mid-March, the CHOC Heart Institute in the Bill Holmes Tower provides all cardiology services within one convenient, pediatric-focused environment. This includes our specialty outpatient cardiology programs:

Heart Murmurs in Children

 

Nita Doshi, M.D., pediatric cardiologist at CHOC Children’s

As Heart Month comes to a close, check out these helpful facts about heart murmurs in children from Dr. Nita Doshi, pediatric cardiologist at CHOC Children’s.

My pediatrician heard a “heart murmur” in my child.  What is a heart murmur?

A “heart murmur” is an extra noise or sound which can be heard when listening to the heart with a stethoscope.  When blood travels through the veins, arteries, and valves of the heart, the flow of blood can create a sound.  This sound has often been described as having a “swishing” or “whooshing” quality. This sound is frequently referred to as a “heart murmur.”

Does the finding of a heart murmur mean that something is wrong with my child’s heart?

It is very important to remember that a “heart murmur” is simply a noise or a sound.  It is a finding detected by listening through a stethoscope during an examination.  Most of the time, heart murmurs are normal and do not indicate anything is wrong with the heart.

How commonly are heart murmurs diagnosed in children?

Studies have estimated that up to 90% of infants and children will have a heart murmur at some point during infancy or childhood.  But of all heart murmurs, only about 1-3% of children will be found to have a congenital heart problem.

What is an “innocent” murmur?

Innocent heart murmurs have also been called:  “benign,” “physiologic,” “functional,” or “flow-related,” meaning that normal blood flow creates a sound which can be heard during examination.  In younger children, it is often easier to hear a murmur because the distance between the heart and the chest wall is typically closer.  Because innocent heart murmurs are related to blood flow as well as changing chest configuration and heart rate, heart murmurs may disappear and reappear at various times.  As an example, periods of increased activity and fever are common times when a heart murmur may be heard.

What is a “non-innocent” murmur?

Heart murmurs can be termed “non-innocent” or “pathologic,” meaning that the sound may represent an abnormality of the heart muscle, walls, valves, or arteries.  For instance, a pathologic murmur can represent the sound of blockage of outflow from the pumping chambers, which dispenses blood to the lungs and the body.  It may also signify a hole within the wall inside the heart, narrowing or malformation of one of the heart valves, leakage of one of the heart valves, or narrowing of one of the arteries supplying blood to the lungs or body.

What may further evaluation of a heart murmur involve?

Your pediatrician may choose to refer your child with a heart murmur to a pediatric cardiologist.  A pediatric cardiologist is a specialist of heart disease in fetuses, infants, children, and young adults.  Your pediatrician or pediatric cardiologist may decide to order an “electrocardiogram,” which is a non-invasive test that measures the electrical activity or rhythm of the heart.  Your pediatrician or pediatric cardiologist may decide to order an “echocardiogram” otherwise known as an ultrasound of the heart, which is another type of non-invasive test that can further evaluate the structure and function of the components of the heart.

Heart Imaging Goes 3-D

And no special 3-D glasses are required. Magnetic resonance (MR) angiography gives our CHOC pediatric cardiac specialists an unprecedented, crystal-clear view into our patients’ hearts and surrounding blood vessels.

If a single picture is worth a thousand words, consider the value of a complete 3-D reconstruction of the heart and the major blood vessels that may be viewed from any angle. These images may also be magnified, flipped, rotated, color-enhanced and even animated into a movie, showing every precise detail in motion.

In children with complex, congenital heart disease, no two hearts are alike. MR angiography has become an indispensable diagnostic tool, providing unparalled views into the deepest abnormal, anatomic structures within a child’s heart. And best of all, this procedure is noninvasive and free of radiation. It is better tolerated by patients than diagnostic cardiac catheterization and does not usually require sedation or anesthesia.

Pierangelo Renella, M.D., CHOC Pediatric Cardiologist

“When standard imaging is not enough, MR angiography offers a way to obtain critical information needed to make complex cardiac diagnoses,” says Pierangelo Renella, M.D., pediatric cardiologist and advanced cardiac imaging specialist at CHOC Children’s. This technology helps surgeons plan safer and more effective procedures, and can be used to follow patients over time as it provides details for making decisions about medication and possible future surgeries.”

“State of the Art” is Our Standard of Care

The CHOC Children’s Heart Institute is the only center in Orange County providing pediatric MR angiography. Our hospital has two magnetic resonance imaging systems, featuring 1.5 and 3 power Tesla magnets — the strongest magnets available for MR magnetic resonance imaging. Just two more reasons why when it comes to caring for infants, children and adolescents with complex, congenital heart conditions — there’s no place like CHOC.

Chest Pain – What Parents Should Know

In honor of American Heart Month, check out these important guidelines to help you determine whether your child’s chest pain could be associated with heart disease. In this Q&A, Dr. Pierangelo Renella, a pediatric cardiologist at CHOC Children’s, explains the signs and causes of this common condition, rarely associated with the heart.

Q: What causes chest pain in children?
A:  The most common cause of chest pain in children is pain in the muscles that make up the chest wall and not the heart itself.  This type of pain is usually referred to as “musculoskeletal pain.”  Another common cause of childhood chest pain is costochondritis, which is inflammation in the cartilages at the ends of the ribs.  Other causes may include respiratory infections, asthma, acid reflux (“heartburn”), or a partially collapsed lung, for example.  These are usually not life-threatening.  However, in rare situations, there are serious forms of heart disease that can cause chest pain, and these usually require a pediatric cardiologist’s assistance to diagnose and treat.

Q: How often is chest pain in children due to a heart problem?
A:  Although childhood chest pain is the second most common reason for referral to a pediatric cardiologist, it only rarely means the child has actual heart disease.

Q: How do I know when my child’s chest pain needs medical attention?
A:  Chest pain that occurs with, or immediately after, exercise should be evaluated further, starting with your child’s pediatrician.  In addition, for chest pain that is associated with fast heartbeat, dizziness, or fainting, or if there is a family history of sudden cardiac death, your pediatrician may refer your child to a pediatric cardiologist.

Q: How can I help prevent my child’s chest pain?
A:  Again, the vast majority of childhood chest pain is not heart-related.  Since the most common causes involve the muscles and bones of the chest wall, the pain should improve with rest and anti-inflammatory medications such as acetaminophen or ibuprofen.  If these treatments do not work, and if the pain is significant, worsening, or associated with other signs and symptoms such as dizziness, fainting, shortness of breath, fast heartbeat, or exercise, make an appointment with your child’s pediatrician immediately.
