Diastology

Question 1

What is the rule with reduced EF?

LA size’s rp;e

Answer 1

Immeditaly moves them to abn diastolic function which makes it at thr 4 grades (only have to look at E:A)

Dont need to look at tissue dopplar

LAE means some higher pressures seen in the past.

Question 2

5 things one can look at for diastology

Answer 2

1. Mitral inflow E:A (most important, and if reduced EF all you need to look at)
2. Pulmonary Veins
3. Dynamic changes
4. Tissue Dopplar
5. LA size

(there is also diastoli strain fyi)

Question 3

First thing really used to assess diastology aside from mitral inflow

3 wave forms of it

How did this perform?

Answer 3

Pulmonry veins

Big peak, smaller peak (kind of like E to A but called A and B and then a downward peak called D

Terribly, atrial duration correlates better.

• too hard

Question 4

What is the thought process for E to e’ ratio

Answer 4

For normal and grade one the E and E’ as well as A and A’ mirror each other not until you get to grade two and grade 3 does the E/E’ go way up if there is increased filling pressures. see figure. e’is the divisor (numerator_)so the ratio goes up if it gets small
