Which valve seperates the areas of greatest pressure difference?
Mitral
Which valve separates the areas of lowest pressure differences?
Tricuspid valve
What vessel lies in the anterior interventricular groove or sulcus?
LAD
Which aortic leaflet is the superior one in the parasternal long axis view?
the right leaflet
which aortic leaflet is the posterior one in the parasternal long axis view?
the noncoronary
from the left parasternal window which of the following are you most likely to get accurate velocity measurements?
a) LVOT
b) Mitral stenosis
c) Pulmonary artery
d) mitral regurgitation
C) Pulmonary artery
The coronary arteries come off the:
Sinuses of valsalva
During which phase do the coronaries fill?
Early diastole
the best images of the ascending aorta are often obtained from which transducer window?
Suprasternal
Name the vessels coming off the arch and most proximal to distal
Innominate(proximal)
Left common carotid
left subclavian artery (Distal)
What cardiac pathology is associated with bicuspid aortic valves?
Coarctation of the aorta
which window do you use to look for the secondary finding in bicuspid valves?
Suprasternal arch
where do most aortic coarctations occur?
the aortic isthmus ( after takeoff of the left subclavian artery)
from the apical 4ch view where are the pulmonary veins located?
rt and lt lower(inferior) pulmonary veins
from the apical 4ch view how do you rotate the transducer to obtain the apical LAX?
Counterclockwise 120 degrees
Where is the coronary sinus located?
Posterior AV groove
TO visualize the coronary sinus in the apical 4ch view you should tilt the transducer”
Posterior
where is the chiari network located?
in the right atrium
what portion of the pulmonary venous PW Doppler represents atrial systole? /
a wave
at what temperature is it unsafe to use a TEE probe?
40-45 degrees celcius
which has the fastest intrinsic rates?
SA node
What is the absolute refractory state?
that period when a muscle cell is not excitable- from phase 1 until phase 3;
what is the relative refractory period?
is during phase 3 and the muscle cell might contract if the stimulus is strong
What is the Frank - Starling law
(length- tension relationship) Incrased volume (preload) = increased contractability
Increased myocardial fiber length= Increased tension (rubber band theory)
