Double-Outlet Right Ventricle (DORV) Flashcards
What is DORV?
-RV takes up both the pulmonary artery and the aorta
-RV has a double outlet
-RV is abnormally big
-LV is abnormally small
What does DORV almost always come with?
DORV almost always comes with a VSD
What other health conditions does DORV also come with? (7)
-Endocardial cushion defects (the walls separating the 4 chambers are poorly formed or absent)
-Mitral valve problems
-Coarctation of the Aorta
-Pulmonary atresia
-Pulmonary valve stenosis (narrowing of the pulmonary valve)
-d-TGA
-Right-sided aortic arch (the aortic arch is on the right side instead of the left)
What does DORV stand for?
Double-Outlet Right Ventricle
Is DORV a critical CHD?
Yes
What are some signs of DORV? (4)
-Enlarged heart
-Heart murmur
-Rapid breathing
-Rapid HR
What are some symptoms of DORV? (5)
-Cyanosis
-Trouble breathing
-Sweating
-Pale
-Poor feeding from becoming tired easily
What is cyanosis?
Cyanosis is the condition of having bluish lips, skin, and nails because of low blood oxygen levels.
What are some exams/tests that are used to diagnose DORV? (4)
-Chest x-ray
-Echocardiogram
-Cardiac catherization
-Heart MRI
What is a chest x-ray?
An x-ray of the thorax
What is an echocardiogram?
An ultrasound of the heart
What is cardiac catherization?
Cardiac catherization is an operation in which a thin, flexible tube/wire (catheter) is inserted into the heart to measure BP and inject dye for special pictures of the heart and arteries.
What is a heart MRI?
An MRI (Magnetic Resonance Imaging) of the heart
What does treatment for DORV require?
Treatment for DORV requires surgery.
Why are surgeries required to treat DORV?
Surgeries required to treat DORV in order to close the VSD and direct blood from the LV to the Ao.
What are the factors that influence the type and number of operations the infant needs?
-The type of DORV
-The severity of the defect
-The presence of other problems in the heart
-The infant’s overall condition
What are some possible complications from DORV?
-Heart failure
-High BP in the lungs
-Death
What happens if the high BP in the lungs (one of the complications from DORV) is left untreated?
If the high BP in the lungs (one of the complications from DORV) is left untreated, it may lead to permanent lung damage)
What may children with DORV need before surgeries or dental treatments? Why?
Children with DORV may need antibiotics before surgeries or dental treatments because it prevents infections in the heart.
