What are the congenital defects known to have an inherited basis and what breeds are associated?
PDA- poodles
Subaortic stenosis- Newfoundlands
Tetralogy of Fallot- Keeshonds
Pulmonic stenosis- beagles
What are the top three most common cardiac congenital defects in dogs (from one to three)
PDA,SAS, and pulmonic stenosis
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
