following is the least likely cause for this symptom?
a. TS
b. constrictive pericarditis
c. aortic coarctation
d. pulmonary HTN - answer✔✔b. constrictive pericarditis
a. HCM
b. constrictive pericarditis
c. moderate AR
d. aortic coarctation - answer✔✔b. constrictive pericarditis
atrial depolarization is represented by what part of the EKG?
a. QRS wave
b. R wave
c. P wave
d. T wave - answer✔✔c. P wave
which echo finding is most consistent with Holt Oram syndrome?
a. dilated aortic root
b. LVH
c. global dysfunction of the LV
d. ASD - answer✔✔d. ASD
which doppler measurement of flow through a stenotic valve best correlates with the same value
obtained during a heart catheterization?
a. maximum peak instantaneous gradient
b. mean pressure gradient
c. peak aortic velocity
d. peak to peak gradient - answer✔✔b. mean pressure gradient
how is the contraction velocity of the LA appendage evaluated?
a. M-mode sample line positioned approximately across the LA and the body of the LAA
b. PW doppler sample volume positioned 1 cm proximal to the entry of the appendage into the
body of the LA
c. m-mode sample line positioned approximately 1 cm proximal to the entry of the appendage
into the body of the LA
d. PW doppler sample volume positioned in the center of the LAA - answer✔✔c. m-mode
sample line positioned approximately 1 cm proximal to the entry of the appendage into the body
of the LA
what is the major advantage of using color doppler in TEE evaluation of a prosthetic valve over
color doppler evaluation of the same value on a TTE exam?
a. TEE can identify turbulence caused by valvular stenosis which cannot successfully be
diagnosed on TTE
b. TEE can use doppler to assess PISA radius of MR which is usually limited by valve masking
on TTE
c. TEE can identify paravalvular leakage which is usually very limited on a TTE
d. TEE can identify valvular dehiscence while TTE usually cannot diagnose this abnormality
with color doppler - answer✔✔c. TEE can identify paravalvular leakage which is usually very
limited on a TTE
you are performing an apical view during the administration of UEA. you notice swirling of the
microbubbles in the apex area. how can you adjust the controls to reduce this artifactual
swirling?
a. inject UEA at a faster rate
b. turn off harmonic imaging
c. decrease the near field gain
d. decrease the mechanical index setting - answer✔✔d. decrease the mechanical field setting
note: increasing the near field gain, reducing the output power also work. injecting at a faster rate
also works but this isn't a control setting
at what point in the cardiac cycle is the LV at its greatest dimension?
