Cardiovascular (10%) Flashcards
What are two examples of very serious complications of Kawasaki dz?
Coronary artery aneurysm
Myocardial Infarction
What is the recommended managment of tetralogy of fallot?
Surgical correction
Prostaglandin E1 prior to surgery to maintain patency of the ductus arteriorsis
What are some clinical manifestations a pt with hypertrophic cardiomyopathy may present with?
Often asymptomatic, 1st sx may be sudden cardiac death
Dyspnea MC initial complaint (90%)
Fatigue
Angina pectoris (75%)
Syncope (pre syncope, dizziness)
Arrhythmias (A fib, V Tach/V Fib)
Sudden cardiac death: adolescent/preadolescent children, esp. during times of extreme exertion –> usually d/t V Fib
What is the mainstay of tx for a pt with Kawasaki dz?
IV Immunoglobulin + High dose ASA
What diagnostic test should be ordered if a pt is suspected to have hypertrophic cardiomyopathy?
Echocardiogram: asymmetrical wall thickness (especially septal) and systolic anterior motion of the mitral valve
CXR: cardiomegaly
ECG: LVH
T/F: Restrictive VSD (left > right-sided pressure) is associated with a poor prognosis
False, it has a GOOD prognosis :)
A patient with ASD may develop a stroke due to _______ _______
Paradoxical emboli
Until what age are ASDs usually asymptomatic?
30 y/o
What kind of murmur is associated with hypertrophic cardiomyopathy?
What does it decrease with?
Increase with?
Harsh systolic ejection murmur
Decrease: Hand grip, squatting, laying supine (increased venous return)
Increase: valsalva and standing (decreased venous return)
A pt with PDA usually has what kind of pulses?
Bounding
wide pulse pressure
Describe the murmur that is associated with VSD
Loud high-pitched harsh, holosystolic murmur at the lower left sternal border (LLSB)
What heart sound, other than a murmur, may be heard in a pt with ASD?
Widely fixed, split S2 that does NOT vary with respirations
What are the three types of Atrial Septal Defects?
Where are they located?
Ostium Primum
Ostium Secundum
Sinus venosus
What kind of murmur is usually associated with ASD?
Where is it best auscultated?
Systolic ejection murmur
Pulmonic area
What does a pt (infant vs older children) with tetralogy of fallot present with?
Cyanosis in infants
Tet spells in older children (periodic episodes of cyanosis relieved with squatting or putting an infant’s knees to chest)
What are the two types of coarctation of the aorta?
Preductal and postductal
What will be seen on CXR in a pt with tetralogy of fallot?
Boot shaped heart
What are the components of tetralogy of fallot?
- RV outflow obstruction
- RV hypertrophy
- VSD (large and unrestrictive)
- Overriding aorta
Hypertrophic cardiomyopathy is a disorder of inappropriate ____ and/or ____ hypertrophy (especially _____)
Left ventricular
Right ventricular
septal
With hypertrophic cardiomyopathy, what is obstructed?
Subaortic outflow obstruction
What is the most common type of VSD?
What are the other three types?
- Supacristal (outlet): 5%, beneath the pulmonic valve. ± aortic valve insufficiency
- Perimembranous: MC type (80%), hole in LV outflow tract near the tricuspid valve
- Inlet (posterior): 10%, located posterior to the septal leaflet of the tricuspid valve
- Muscular: 5-20%, usually multiple holes in a “swiss cheese” pattern
Kawasaki disease causes necrotizing vasculitis in what blood vessels?
Medium and small vessels
Cornoary arteries
