is normally lower than resistance in the systemic vascular system? - ANSWER-
The flow through the aortic valve reaches a peak velocity faster than the flow
through the pulmonary valve
What is another term for hypereosinophilia? - ANSWER- Loeffler endocarditis;

What secretes the pericardial fluid? - ANSWER- Visceral pericardium
What is the first parameter to consider when assessing a patient for diastolic
dysfunction? - ANSWER- The LV EF
What does medial cystic necrosis cause? - ANSWER- Dilated aortic root &
ascending aorta (breakdown or damage of connective tissue in the large arteries)
Most common complication of a septal myectomy? - ANSWER- VSD
What happens to the aortic valve in HOCM? - ANSWER- There will be mid-
systolic notching
