PR Flashcards
What are three etiologies of pulmonic regurgitation??
-primary valve disease like stenosis or endocarditis
-PHTN
-carcinoid heart disease
Carcinoid heart disease is?
Carcinoid tumors that affect the heart
90% of carcinoid tumors are located in the?
GI tract
What percentage of people with carcinoid disease end up developing carcinoid heart disease?
50%
Pulmonary regurgitation can lead to what 2 things?
-RV fluid overload and dilation
-Right side heart failure
True or false- moderate pulmonary regurgitation may be well tolerated for years?
True
What is the murmur associated with pulmonary regurg?
Low pitched diastolic murmur LSB that may increase with inspiration
True or false- the murmur associated with PR may increase with inspiration
True
What is the Graham Steele Murmur associated with?
PHTN.
What does the Graham Steele murmur sound like?
High pitched blowing diastolic murmur LSB
True or false - with pulmonic regurgitation, tricuspid valve fluttering is common?
False it’s rare
RV dilation with ____of the LV septum ____is a echo sign of PR
Displacement
Posteriorly
With pulmonary regurgitation is there diastolic turbulence in the RVOT?
Yes
How do you calculate the pulmonic artery end diastolic pressure and what is the formula?
You calculate using the right atrial pressure.
The formula is: RAP + EDP
You may need to convert the end diastolic pressure first by using the modified bernouli equation 
What else do you need to estimate pulmonary artery end diastolic pressure?
The RAP
