Pulmonary Regurg Flashcards
Pulmonary Regurg: Etiology
- Primary valve disease
- Pulmonary hypertension
- Carcinoid heart disease
- Trivial/mild regurg is common
Pulmonary Regurg: Etiology–> Primary valve disease
- Stenosis
2. Endocarditis
Pulmonary Regurg: Pathophysiology
- RV volume overload
- Severe regurg may cause right heart failure
- Even moderate regurg will be well tolerated for years
- Increased risk for endocarditis
Pulmonary Regurg: Pathophysiology–> RV volume overload may lead to?
RV dilation
Pulmonary Regurg: Pathophysiology–> Severe regurg may cause?
Right heart failure
Pulmonary Regurg: Murmur
Low pitched diastolic murmur (LSB) may increase with inspiration
Pulmonary Regurg: Physical signs–> With pulmonary hypertension murmur
A high pitched blowing diastolic murmur (Graham-Steele) may be heard (LSB)
Pulmonary Regurg: Echo
- RV dilation with displacement of LV septum posteriorly
2. TRicuspid valve fluttering is rare
Pulmonary Regurg: Doppler RVOT
Diastolic turbulence in the RVOT
Pulmonary Regurg: Doppler–> Map the regurg area with?
Pulsed or color flow doppler
Pulmonary Regurg: Doppler–> Severe PI spectral trace is
NOT holodiastolic
How would you calculate pulmonary artery end diastolic pressure?
Pulmonic insufficiency velocity
PAEDP equation
PAEDP= RAP+ EDP(converted from the EDV)
