---|---|---|---|---|---|
show | the septum opening between the left and right atria d/t the foramen ovale not closing
🗑
|
||||
What happens within the body because of ASD? | show 🗑
|
||||
show | may be asymptomatic, fatigue, delayed growth, CHF, soft-systolic heart murmur
🗑
|
||||
how is ASD diagnosed? | show 🗑
|
||||
show | closed/patched through a surgical process, cardiac catheterization using a septal occluder
🗑
|
||||
show | the ductus arteriosus fails to close and the blood is pushed from the aorta to the pulmonary artery
🗑
|
||||
show | increases the blood flow to lungs causing right ventricle hypertrophy and increased pressure in the pulmonary circulation
🗑
|
||||
What are the signs and symptoms of PDA? | show 🗑
|
||||
If a child has PDA, what are they at a risk for? | show 🗑
|
||||
how is PDA diagnosed? | show 🗑
|
||||
show | prostaglandin inhibitor because it helps to stimulate the closure of the ductus arteriosus
🗑
|
||||
What occurs with a Ventricular Septal Defect (VSD) ? | show 🗑
|
||||
show | most are asymptomatic, dyspnea, tachypnea, delayed growth patterns, reduced fluid intake, CHF
🗑
|
||||
show | chest x-ray, ECG, echocardiogram
🗑
|
||||
show | many spontaneously close in the 1st year of life. If not, defects are usually repaired between 6-8 months
🗑
|
||||
What is Tetralogy of Fallot (TOF)? | show 🗑
|
||||
show | narrowing of the pulmonary valve
🗑
|
||||
What occurs within the body with TOF? | show 🗑
|
||||
show | can be cyanotic and hypoxic, delayed growth, metabolic acidosis, clubbing of fingers, exercise intolerance
🗑
|
||||
How is TOF diagnosed? | show 🗑
|
||||
How is TOF treated? | show 🗑
|
||||
show | a narrowing of the aorta
🗑
|
||||
show | it restricts flow of blood to the body, causing the Left ventricle to work hard to force blood through narrowed aorta. Over time, will lead to CHF.
🗑
|
||||
show | the blood pressure will usually be higher in the arms and lower in the legs. Pulses are strong and bounding in the arms, neck and head and lower pulses are weak or absent.
🗑
|
||||
How is coarctation diagnosed? | show 🗑
|
||||
show | Is usually repaired during the first year of life via balloon dilation, anastomosis, or surgical resection.
🗑
|
||||
What is transposition of the great arteries? | show 🗑
|
||||
show | cynosis(that may not improve with oxygen), hypoxia, acidosis, CHF, tachypnea, delayed growth
🗑
|
||||
show | chest X-ray, echocardiogram
🗑
|
||||
show | Prostaglandin E is given IV immediately to maintain patency of the ductus arteriosus prior to surgical intervention.
🗑
|
||||
show | it decreases cardiac output
🗑
