Name the tricuspid leaflets Ans- Posterior and Anterior
The coronary arteries come off of the.. Ans- Sinus of Valsalva
Name the vessels coming off the arch and the most proximal or distal. Ans- Innominate (proximal), left carotid, and the left subclavian (distal)
What cardiac pathology is associated with bicuspid aortic valves? Ans- Coarctation of the Aorta
Where do the most aortic Coarctation occur? Ans- After the take-off of the left subclavian artery, or within the aortic isthmus
Where are the pulmonary veins loca? Which ones are seen in this view? Ans- Rights and left superior (upper) pulmonary veins
Where is the coronary sinus located? Ans- Posterior AV groove
To visualize the coronary sinus in the apical 4 chamber view you should tilt the transducer.. Ans- Posterior
During which phase do the coronaries fill? Ans- early diastole
Where is the chiari network located? Ans- RA
What portion of the pulmonary venous PW Doppler represents atrial systole? Ans- A wave
Know frequency for TEE probes versus TTE Ans- TTE probes are usually higher 5-
7MGz, while TTE probes are 2-7MHz
At what temperature is it unsafe to use a TEE probe? Ans- 40-45C
Know TEE views by esophageal level (know mid esophageal- ME and transgastric) and degrees. Ans- 4ch- 0 degrees
2ch- 90 degrees LAX- 120 degrees
Why is the SA node the primary pacemaker? Ans- The SA node has the highest intrinsic rate of any cardiac tissue.
The save of contraction (depolarization) moves from the endocardium to the epicardium. Ans- Inside to outside. Look at the purkinje fibers above.
What is the absolute refractory state? Ans- That period when a muscle cell is not excitable- from phase 1 into phase 3; the 'relative refractory period' is during phase 3 and the muscle cell might contract if the stimulus is strong.
