Cardiology Flashcards
What are the 4 components of the “tetralogy” of Tetralogy of Fallot?
Overriding aorta, VSD, RVOT obstruction, RVH
You are telling the cardiology fellow about a patient with a newly-detected systolic murmur. Being academic and because she likes teaching, she asks you what the S2 sounds like. Why did she ask that?
Loud S2 suggests pulmonary HTN. Some causes of murmurs, such as VSD’s, if untreated and significant, can eventually lead to the dangerous sequela of pulmonary hypertension.
What do ASDs, VSDs, and PDAs have in common? (What physiologic significance do they share?)
They all allow for shunting between the “left” and “right” heart. The overall degree of shunting could be worse if a patient has several of these lesions (vs. just one of them) because of having more avenues for shunting.
