congenital cardiovascular disease Flashcards
what is the most common congenital cardiovascular disease
VSD
then ASD, PDA
are the following diseases cyanotic?
ASD, VSD, PDA
no
are the following cyanotic?
fallots
transposition of great vessel
yes
will these be cyanotic?
pulmonary stenosis
valve atresia
hypoplastic left heart
yes
what are possible signs of CHD
murmur tachycardia tachypnoea cyanosis heart failure clubbing squatting syncope SOB failure to thrive
what are possible complications of CHD
infective endocarditis (abnormal endothelium) paradoxical embolism polycythaemia so thrombosis
what Is eisenmengers complex
reversed shunt due to pulmonary hypertension in VSD
what investigations might confirm CHD
echocardiography
cardiac cathertisation
what type of ASD is most common
ostium secundum - mid septum , less serious
what are the signs of an ASD
dilation of pulmonary artery
murmur over pulmonary valve
acyanotic
may lead to right heart overload
what are the signs of a VSD
pansystolic murmur
may be heart failure
what murmur would you hear in a PDA
machinery murmur
bounding pulse
What drug treats PDA
indomethacin- inhibits prostaglandin
what are the 4 parts of fallots tetralogy
VSD
over riding aorta
pulmonary valve stenosis
RVH
how does squatting help
diverts blood to pulmonary arteries by raising aortic and systemic pressure
