Question | Answer |
---|---|
Aortic insufficiency is indicated by a/an: | wide pulse pressure |
PCW= 12/43/20. You suspect: | mitral regurgitation |
AO= 180/50/93. You suspect: | Aortic regurgitation |
Why is the Diastole low in aortic regurgitation? | The AO has a second room (LV) to deposit the blood |
LV = 188/9/15. AO= 140/90/107. You suspect: | Aortic stenosis |
PCW= 36, LV edp = 18. What abnormality could cause such a gradient? | mitral stenosis |
A pullback gradient between LV apex and LV outflow tract suggests: | HOCM |
Large "a" waves in the LA waveform suggest: | Mitral stenosis |
In atrial fibrillation, which of the following cannot be measured? LV EDP, PCW, PA mean, RA a waves | RA a waves |
Which measurement best indicates right heart preload? PCW mean, PA diastolic, RA v waves, RV edp, RV mean pressure | RV edp |
Which of the following occurs in tricuspid stenosis? elevated RV systolic, Canon "v" waves, large "a" waves in the RA, elevated PA mean pressure, All of the above | Large "a" waves in the RA |
The square root sign in an RV waveform suggests | Restrictive cardiomyopathy or constrictive pericarditis |
In cardiac tamponade: | Right heart pressures elevate and equalize |
In pulmonary embolus: | PA diastolic pressure exceeds PCW |
In pulmonic stenosis: | There is a systolic gradient from RV to PA |
In acute VSD | RV pressures elevate |
PA= 64/38/47. What condition is consistent with this pressure? | PULMONARY HYPERTENSION |
SVC Sat _ 65%, RA = 66%, RV = 76%, PCW = 99% | VSD |
Stenosis of semilunar valves would be indicated by: | a systolic gradient |
Stenosis of atrioventricular valves would be indicated by: | a diastolic gradient |
A patient's pulmonary capillary wedge pressure shows a deep Y descent. All diastolic pressures were equal and show a plateau. What diagnosis do these pressure reading suggest? | Constrictive pericarditis or restrictive cardiomyopathy |
