This lecture discusses basic systolic function.

Note: Myocardial perfusion is variable in patients (we are all unique) and the perfusion of the various 17 segments presented in this lecture was the same as the perfusion used by the ASE/SCA/AHA/NBE for many years. In 2013 the ASE produced a NEW BASIC EXAM guidelines PDF with slightly different wall segment perfusion.

IT IS CRITICAL THAT YOU DOWNLOAD AND READ THIS PDF. Here is the link:http://www.asecho.org/wordpress/wp-content/uploads/2013/05/Basic-Perioperative-TEE-Exam.pdf

On page 449 of this article there is a figure describing perfusion of the myocardial segments. This is the perfusion I would use for the basic exam. Sorry for any confusion this has created. Myocardial perfusion varies from patient to patient and the guidelines are a moving target as well. Please give me a shout if you have questions: tommy@ptemasters.com

ERROR: At around the 35:00 mark. The area of the LVOT is calculated using π x (diameter)^{2} instead of Pi (π) x r^{2}. There is a similar point earlier in the lecture the diameter of the main PA is used to calculate the CSA of the PA without multiplying by 1/2 to get the radius.

Special thanks to Scott Davis who alerted us to the error.

We will re-record the lecture and remove the error when time permits. Sorry for the mistake.
