|
|
|
What is the most common congenital defect in cats?
|
ventricular septal defect (aka- endocardial cushion defect)
|
|
|
what is PDA and when does it occur?
|
PDA occurs when the fetal ductus arteriosus fails to close within 2-3 days after birth
|
|
|
What type of shnting and overload is seen with PDA?
|
left-to-right shunting of blood, with a volume overload in the left atrium and ventricle. may lead to left sided CHF
|
|
|
describe the mumur auscultated with PDA
|
continous or "machinery" mumur that is loudest on the left side and often is accompanied by a precordiall thrill
|
|
|
how will a reverse pda patient present
|
normal or pink oral mucous membranes and cyanotic membranes elsewhere
|
|
|
when is surgical ligation of the shunt recommended for a pda
|
at 2 to 4 mo of age
|
|
|
when is surgery recommended for a reverse pda
|
surgery is contraindicated b/c closure of the duct will result in acute right ventricular failure and death
