Sudden Arrhythmias – What Causes SADS?

The conditions responsible for SADS cause a cardiac arrest by bringing on a ‘ventricular arrhythmia’ (a disturbance in the heart’s rhythm), even though the person has no structural heart disease. There is a group of relatively rare diseases called ion channelopathies that affect the electrical functioning of the heart without affecting the heart’s structure. ThisContinue Reading

Special Bypass Procedure Used During Infant Heart Surgery Does Not Impair Later Neurological Outcomes in Children

Congenital heart defects (CHD) are the most common birth defects in humans, affecting 8 per 1000 live births with one third of affected children requiring intervention in early infancy. Increasing numbers of survivors combined with developmental expectations for independence, behavioral self-regulation and academic achievement have led to a growing identification of neurobehavioral symptoms in someContinue Reading

Vocal Cord Paresis Can Occur After Open Heart Surgery

One of the complications Chloe endured after the Arterial Switch Operation was Left Vocal Cord Paresis (weakness in the left vocal fold). Cardiac surgery represents a risk to normal voice function as the nerves serving the larynx (voice box) are routed near the heart. Damage to this nerve during open heart surgery is not uncommon.Continue Reading

What is Cytogenetic Testing?

Cytogenetic testing examines the number and structure of a person’s chromosomes. Chromosomes are tightly bundled packages of DNA present in almost every cell in our bodies. Most people have 46 chromosomes in nearly every cell of their bodies. These chromosomes exist in two sets: we inherit one set of 23 chromosomes from our mother andContinue Reading

CHDs Attribute to Acquired Scoliosis

Complications of the heart at birth are a frightening experience for new parents. In nearly one percent of all births, children are born with congenital defects of the heart that can lead to prolonged hospital stays and increased medical costs throughout childhood. For some children, the congenital heart complication will require surgical intervention which mayContinue Reading

CHD Affects Baby’s Brain Development In Utero?

The brains of full-term infants with congenital heart disease appear more similar to those of premature newborns than to the brains of normal term infants, a study conducted by researchers at UCSF has found. The study suggests that the mental and physical impairments in children with congenital heart disease may also have their origins inContinue Reading

4-D Heart Imaging (PC VIPR)

Heart disease is the number one killer in the U.S, and congenital heart disease is the most common birth defect around the world. About five million people in the U.S. have heart failure, and it kills 300,000 people a year. Current lengthy MRI heart imaging technology has led to long waiting lists but remarkable newContinue Reading

Organ Donation Policies Vary Amoung Children’s Hospitals

Children’s Hospitals have widely varying policies on organ donation after cardiac death (DCD), according to researchers, who asked 124 hospitals in the United States, Puerto Rico and Canada about their policies in 2007 and 2008. The study authors received responses from 105 hospitals. They found that 72 percent of them had DCD policies, while policiesContinue Reading

Milrinone Tied to Tachyarrhythmia After Congenital Defect Repair

After repair of congenital heart defects, children are at higher risk for significant tachyarrhythmias early after surgery if they’re given milrinone, according to a study from Tennessee. Milrinone is often used to reduce the risk of low cardiac output syndrome, the investigators noted in a report published online September 7 in the American Journal ofContinue Reading

Preclinical Tests Funded for Pumps for Kids, Infants and Neonates (PumpKIN)

The National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, has awarded four contracts totaling $23.6 million to begin preclinical testing of devices to help children born with congenital heart defects or those who develop heart failure. The four-year program is called Pumps for Kids, Infants, and Neonates (PumpKIN). EachContinue Reading
