Test #2 (PDA, PPHN, Cardiac probs, Hydrops) Flashcards
(72 cards)
Which of the following lesions results in active congestions of the pulmonary vasculature?
Truncus arteriosus
The most common heart defect presenting in the first 24 hours of life with cyanosis and increased vascularity is
transposition of the great arteries
Other defects associated with d-transposistion of the great arteries include?
aortic arch defects
Congestive heart failure develops early in d-transposition of the great arteries in the presence of?
PDA or VSD
What shape of the heart is characteristic of TGA on chest x-ray?
egg
In cases of d-TGA, the aortic arch is usually?
left-sided
Heart Failure typically presents at ____ days in cases of coarctation of the aorta
7-14day
Which type of coarctation is typically identified in the neonatal periods?
preductal
In coarctation of the aorta with a discrete constriction the constriction typically occurs at the opposite side of the insertion of the
ductus arteriosus
Congestive heart failure causes by coartation of the aorta is exacerbated by the presence of
VSD or PDA
X-ray findings consistent with coarctation of the aorta include which of the following heart shapes?
Globular
In the presence of T of F with pulmonary atresia, pulmonary perfusion may be supplied by flow through a
PDA
The timing of the presentation of TOF is dependent on the degree of
Right ventricular outflow obstruction
Initial signs of TOF in the NB period inculde
respiratory distress, cyanosis, murmur
TOF includes which of the following findings?
Pulmonary stenosis
Chest x-ray findings in TOF include pulmonary arteries which appear>
thin and stringy
The heart size in an infant with TOF is typically
Normal or slightly enlarged
Infant with TOF, the heart assumes which shape?
Boot
Congestive heart failure accompanies TOF in the presence of
Tricuspid regurgitation
Clinical presentation of pulmonary atresia with intact septum include which of the following?
severe cyanosis, mild tachypnea, murmur
In cases of pulmonary atresia with intact Ventricular septum the cardiac size is dependent on the
amount of tricuspid regurgitation
In obstructive lesions, cardiomegaly occurs because of
hypertrophy
The greatest source of error in interpreting cardiac size is
poor inspiration
the neonate’s heart is normally globular at birth because the
right ventricular is enlarged (in adults its smaller than the left ventricular)
