Abnormal Color Doppler Flashcards
What is MITRAL STENOSIS
MV does not open wide. Restricted in its opening and blood volume has to go thru smaller space at higher velocity
What views can we detect MITRAL STENOSIS?
- A4
- A3
- A2
What would velocity would indicate MITRAL STENOSIS?
> 1.3 m/s
Draw EKG and Waveform for MITRAL STENOSIS
What causes a loss of steepness in MITRAL STENOSIS waveform?
since blood is moving through a smaller hole, volume needs to be continuously pushed to maintain the continuity of flow
CW, PW OR BOTH for MITRAL STENOSIS?
CW
( both for normal )
What is MITRAL REGURGITATION?
MV is leaking when it’s closed, due to hole/defect
In what views can you find MITRAL REGURGITATION?
A4 , A3, A2
Draw EKG and Waveform for MITRAL REGURGITATION
REMEMBER MV WILL BE CLOSED
CW, PW OR BOTH FOR MITRAL REGURGITATION?
CW
What is LVOT OBSTRUCTION
opening in LVOT is narrowed, could be due to hypertrophy of septum
In what views do we find LVOT OBSTRUCTION?
A5 or A3
What would the velocity be if LVOT OBSTRUCTION?
> 1.1m/s
Draw EKG and Waveform of LVOT OBSTRUCTION
PW, CW OR BOTH FOR LVOT OBSTRUCTION
PW for location but then CW for velocity
What is AORTIC STENOSIS
obstructed AV, narrow opening
What is the velocity when there is AORTIC STENOSIS?
> 1.7 m/s
In what views do we find AORTIC STENOSIS?
A5, A3, SSN
Draw EKG and WAVEFORM FOR AORTIC STENOSIS
(remember SSN)
CW, PW OR BOTH FOR AORTIC STENOSIS
CW
What is AORTIC INSUFFICIENCY
AV is leaking when closed due to hole/defect
In what views can we find AORTIC INSUFFICIENCY?
A5 , A3, SSN
Draw EKG and WAVEFORM for AORTIC INSUFFICIENCY.
remember SSN
What is TRICUSPID STENOSIS
TV is restricted in its opening, stenosed
What velocity indicates TRICUSPID STENOSIS?
> .7 m/s
In what views can we find TRICUSPID STENOSIS?
A4, AV Level, RVIT
CW, PW OR BOTH for TRICUSPID STENOSIS?
CW
Draw EKG and Waveform for TRICUSPID STENOSIS
What is TRICUSPID REGURGITATION?
TV is leaking when closed due to defect
In what views can we see TRICUSPID REGURGITATION?
A4 , AV LEVEL, RVIT
Draw EKG and Waveform of TRICUSPID REGURGITATION
What is PULMONIC STENOSIS?
PV is restricted
What velocity indicates PULMONIC STENOSIS?
> 1.3 m/s
What views can we see PULMONIC STENOSIS?
RVOT, AV LEVEL
Draw EKG and Waveform of PULMONIC STENOSIS
What is PULMONIC INSUFFICIENCY
PV is leaking when closed due to a defect
What views can we see PULMONIC INSUFFICIENCY?
AV LEVEL, RVOT
Draw EKG and Waveform of PULMONIC INSUFFICIENCY
CW, PW OR BOTH FOR PULMONIC INSUFFICIENCY?
CW
