How long can a baby live with transposition of the great arteries?

According to the National Heart, Lung, and Blood Institute (NHLBI), TGA affects roughly 5 out of every 10,000 babies. The defect is found more frequently in Caucasians. Untreated, more than 50% of infants with transposition will die in the first month of life, 90 % in the first year.

How many babies are born with transposition of the great arteries?

The Centers for Disease Control and Prevention (CDC) estimates that about 1,153 babies are born with TGA each year in the United States. This means that every 1 in 3,413 babies born in the US is affected by this defect.

Can transposition of the great arteries be passed down?

Abstract. Background Transposition of the great arteries (TGA) is considered to be associated only rarely with genetic syndromes and to have a low risk of precurrence among relatives of affected patients.

When a newborn has a transposition of the great arteries The only chance for survival is?

Untreated, over 50 percent of infants with transposition will die in the first month of life. Ninety percent will die in the first year.

What causes baby TGA?

TGA is a congenital heart defect. This means it’s a problem with the heart’s structure that your child was born with. The exact cause is unknown, but most cases seem to occur by chance.

Can TGA be detected before birth?

TGA is sometimes diagnosed by fetal ultrasound before the baby is born. First trimester screening for chromosomal abnormalities is a good screening tool to identify patients who might be at an increased risk for cardiac defects.

How much does TGA surgery cost?

The median costs were $60,000, in 2012 dollars (range: $25,000 to $549,000). The median age at operation was 5 days (range: 1 to 12 days).

Can transposition of the great arteries be misdiagnosed?

Often misdiagnosed as transposition of the great arteries in utero, malposition of the great arteries results in a conotruncal inverted twist with normal ventricular looping (ventricular dextro-loop)(8).

Are babies with heart defects fussy?

They can cause symptoms such as: Rapid breathing or shortness of breath. Heart murmurs or irregular heartbeat. Unusual fussiness.

How is transposition of the great arteries repaired in a baby?

Surgery: Within a baby’s first two weeks, transposition of the great arteries is surgically repaired through a procedure called an “arterial switch.” While supported by a heart-lung machine, the aorta and pulmonary arteries are disconnected, then “switched” and reconnected to their proper ventricles.

How common is transposition of the great arteries?

Transposition of the Great Arteries (TGA) There are two types of the malformation, d-TGA where no oxygen reaches the body and l-TGA where some oxygenated blood circulates. In the US, the Centers for Disease Control estimate that about 1,901 infants are born each year with TGA, or about one for every 2,000 births.

What is dextro-Transposition of the great arteries?

The condition is also called dextro-transposition of the great arteries. A rarer type of this condition is called levo-transposition of the great arteries. Transposition of the great arteries changes the way blood circulates through the body, leaving a shortage of oxygen in blood flowing from the heart to the rest of the body.

What is levo transposition of the great arteries?

Levo-transposition of the great arteries. Adults often also have abnormal function of the valve guarding the right ventricle (tricuspid valve). Abnormal valve and ventricular function can cause heart failure. Treatment such as valve replacement, ventricular assist devices or a heart transplant may eventually be needed.
