What does the congenital heart defect coarctation usually affect?
Coarctation of the aorta is generally present at birth (congenital). Although the condition can affect any part of the aorta, the defect is most often located near a blood vessel called the ductus arteriosus. Symptoms can range from mild to severe.
What is associated with coarctation of aorta?
In the current era, coarctation of the aorta mortality is often determined by patient age, patient size, and associated major cardiovascular anomalies. Associated problems that may contribute to death or morbidity include hypertension, intracranial hemorrhage, aortic rupture or dissection, endocarditis, and CHF.
How is coarctation of the aorta diagnosed in newborns?
Pulse oximetry is a simple bedside test to determine the amount of oxygen in a baby’s blood. Low levels of oxygen in the blood can be a sign of a CCHD. Newborn screening using pulse oximetry can identify some infants with a CCHD, like coarctation of the aorta, before they show any symptoms.
Which of the following defects result in increased pulmonary blood flow?
Increased pulmonary blood flow at increased pulmonary artery pressure: Ventricular septal defect (VSD) Atrioventricular septal (canal) defects. Patent ductus arteriosus (PDA)
How is coarctation of the aorta diagnosed?
Coarctation of the aorta is usually diagnosed by echocardiogram (ultrasound pictures of the heart). Cardiac magnetic resonance imaging), cardiac CT (computerized tomography scan), and cardiac catheterization angiography also show aortic narrowing.
Does coarctation of aorta cause murmur?
The murmur associated with coarctation of the aorta may be nonspecific yet is usually a systolic murmur in the left infraclavicular area and under the left scapula. Additional murmurs that result from the presence of associated abnormalities, such as VSD or aortic valve stenosis, may also be detected.
Is coarctation of aorta curable?
Coarctation of the aorta can be cured with surgery. Symptoms quickly get better after surgery. However, there is an increased risk for death due to heart problems among those who have had their aorta repaired.
What is the coartación of the aorta?
La coartación de la aorta es un defecto de nacimiento en el cual una parte de la aorta, el tubo que lleva la sangre oxigenada al cuerpo, es más estrecha que lo usual. ¿Qué es la coartación de la aorta? La coartación de la aorta es un defecto de nacimiento en el cual una parte de la aorta es más estrecha que lo usual.
When is coarctation of the aorta suspected?
Suspicion for coarctation of the aorta is usually raised when there is ventricular disproportion in fetal life (with a smaller left than right ventricle) (Fig. 2).
What is the prognosis of coarctation of the aorta?
The condition can range from mild to severe, and might not be detected until adulthood, depending on how much the aorta is narrowed. Coarctation of the aorta often occurs along with other heart defects. While treatment is usually successful, the condition requires careful lifelong follow-up.
What is the prenatal diagnosis of fetal coarctation?
The prenatal diagnosis of fetal coarctation is still challenging. It is mainly suspected by ventricular disproportion (smaller left ventricle than right ventricle). The sensitivity of ventricular discrepancy is however moderate for the diagnosis of coarctation and there is a high false positive rate.
