Resources (access to ultrasound machines, sim
machines, standardized patients)
• Target audience/level of learners
• For this sample module, we are assuming learners
are MS 1/2 (preclinical) with basic understanding of
knobology, basic principles of ultrasound, some
scanning exposure, basic knowledge of cardiac
anatomy and physiology

Goals and Learning Objectives
• Goal: Understand the basic structure of the heart
through the use of standard ultrasound.
• LO’s:
– Identify the major structures (chambers and valves) in
ultrasound images of the heart.
– Properly orient the patient to obtain (or recognize
and describe) the standard views of transthoracic
cardiac ultrasound and identify the utility of each
view.
– Demonstrate sensitivity to the patient while
performing cardiac ultrasound. (Assumes students are
scanning).
Potential LO’s for Future Sessions
• Physiology (including introduction to Doppler on
ultrasound)
– Correlate events in the cardiac cycle with their appearance
on ultrasound.
• Physical Diagnosis
– Effectively communicate findings to patient, other student,
or other healthcare professionals
– Relate echocardiographic views to cardiac auscultations
• Pathology
– Understand how valvular dysfunction alters normal
doppler flow on ultrasound.
Prework
• Goal: Review cardiac anatomy and physiology,
basic components of ultrasonography
– Possible approaches to accomplish goal:
• Online modules (with or without assessment quiz)
• Lecture based session
• Textbook readings
– Possible formative assessment of prework
completion/understanding
Module Structure
• Review of prework
– TBL session, clicker questions integrated into a
large group session
• Break into smaller groups for ultrasound
component
– Scanning session or demonstration by faculty or
simulation session
– Approach implemented determines students’ skill

Assessment of Students
• Computer module to test students’ ability to
properly identify probe placement and/or 3
dimensional plane of echo images.
• Case vignette to ask students which cardiac
view would be appropriate to evaluate
necessary structures.
Sample Student Assessment (MS 1)
• 35 year old woman with mitral valve prolapse
• Which cardiac ultrasound view(s) is/are most
appropriate to visualize the pathologic
structure(s)? Explain your reasoning.
Sample Student Assessment (MS 2)
• 35 year old woman presents to the ER with
atypical chest pain and shortness of breath.
She is found to have a murmur and click on
cardiac auscultation. (could also give
presentation and have students listen to the
heart sounds with headphones and identify the
murmur and click themselves).
• Which cardiac ultrasound view(s) is/are most
appropriate to visualize the pathologic
structure(s)? Explain your reasoning.
