Congenital Heart Disease Flashcards
PVR drops to its minimum around
6-8 weeks of age
Heart on CXR should be
should be less than 50% of diameter, without pulmonary vascular markings
Poor feeding in infants with CHF is due to
fatigue, dyspnea
Signs of CHF
delayed milestones, change in activity level, dyspnea, tachypnea, frequent respiratory infections
Signs of systemic congestion
Hepatomegaly
Peripheral edema
Evaluation of CXR
Heart size/silouette
Pulmonary blood flow
Common consequence of congenital heart disease
Volume overload lesions
What to auscultate on CHF baby?
Heart rate/regularity
Heart murmurs
What to inspect on CHF baby?
General appearance, nutritional state Color: cyanotic, pale? Resp rate/retractions: full minute --> 40 breaths/min normal Cold sweat on forehead --> sympathetic compensation for decreased CO Signs of diminished myocardial performance --> Precordial bulge --> hyperdynamic precordium
Key labs for CHF baby
CXR: heart size/silhouette, pulmonary blood flow
Electrocardiogram: heart rate, rhythm, if LVH
Echocardiagram: visualize anatomy, function
When PVR is lower than SVR, flow begins across
Ventricular septic defects
–> CHF happen 2-3 months of age when PVR at lowest level
How to manage CHF baby
Enhance caloric intake
Digitalis, diuretics
Surgical management
What to palpate on CHF baby?
Peripheral pulses
Peripheral edema
