Cardiology Flashcards
0
Q
- decreased perfusion/pulses in LE
- Sx of CHF, shock, acidosis, lethargic
- Tx: Prostin
A
Coarctation of the Aorta
1
Q
- difficulty feeding, FTT, tachypnea, tachycardia
- Tx: diuretics
A
CHF
2
Q
- TGA
- TOF
- TA
- TAPVR
A
Cyanotic heart disease
3
Q
- iron in the Hb molecule is defective making it unable to effectively carry O2 to the tissues
- congenital or acquired
- cyanosis
- child having formula mixed with well water
- acidosis, tachycardia, and shock (no resp distress)
- Tx: methylene blue
A
Methemoglobinemia
4
Q
- none of the 4 veins that drain blood from the lungs to the heart are attached to the LA
- oxygenated blood drains into the RA instead
- incompatible with life w/o PDA, PFO
- veins may pass through the diaphragm causing obstruction
- FT infant with incr RVV activity, cyanosis & pulm edema, single S2, short systolic murmur
- Xray: normal sized heart + pulm congestion
A
TAPVR
5
Q
- good APGARs at birth
- cyanosis on day 2
- tachypnea and decr pulm markings on CXR
- Tx: Prostin
A
Ductal dependent lesions
6
Q
- pulmonary stenosis
- overriding Ao arch
- VSD
- RVH
- palpable RV impulse, single S2
- EKG: RVH
- CXR: boot shaped heart
- MC heart condition OVERALL
A
TOF
7
Q
- hypercyanotic hypoxic episodes
- Triggers: anemia
- results from incr R to L shunting
- Tx: push knees to chest (incr PVR), morphine, phenylephrine, propranolol, volume expansion
A
Tet spell
8
Q
- underdevelopment of the LV, Ao, and Ao valve
- severe CHF, marked cardiomegaly, precordial hyperactivity, loud S2
- no murmur (pulm and Ao pressures are equal)
- Tx: prostin
A
HPLHS
9
Q
- Ao connected to the RV and the RA to the LV
- MC CHD presenting with cyanosis in the first week of life
- blood must mix either through PFO ro PDA (ductal dependent)
- tachypnea, SINGLE S2
- CXR: egg shaped heart, incr pulm vascularity
- Tx: prostin, balloon septostomy
A
TGA
10
Q
- generalized facial swelling, fatigue, wt loss, night sweats, dusky color from venous stasis
- normal sats
A
SVC syndrome
11
Q
- newborn in resp distress shortly after delivery
- SpO2 LE<UE
- incr workload RV, precordial lift
- PVR>SVR
- R to L shunt
- common with pulm disease
A
Persistent Fetal Circulation
12
Q
- 1-2 week h/o lethargy, low grade fever
- splenomegaly, petichiae, tender lesions on pads of fingers and toes, systolic ejection click at apex, diastolic murmur on the right
- confirm with blood culture
- MC S. aureus in ABE
- MC Strep viridans in SABE
A
Endocarditis
13
Q
- recent URI leading to tachycardia
- enlarged liver, gallop
- MC causeL cocksackie B
- pulsus paradoxus, EKG low voltage, abnl T waves, ST depression
- Dx: viral serology
- steroids are controversial
A
myocarditis
14
Q
- inflammation of pericardial sack involving epi and pericardium
- causesL viral or collagen vascular disease
- may be accompanies by effusion
- muffled heart sounds, pericardial friction rub, low grade fever, JVD
- L sided chest pain worse supine
- CXR: cardiomegaly**
- echo: pericardial fluid
- Tx: pericardiocentesis
A
Pericarditis
