Imaging Studies for Cardiovascular System II:Types of Echocardiography

323
Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Summary

Blocked practice, involving repeated performance of a fixed sequence, was more effective for learning resuscitative transesophageal echocardiography (TEE) on a simulator than variable practice. This finding suggests a specific training method may improve TEE skill acquisition.

Area of Science:

  • Medical Education
  • Emergency Medicine
  • Cardiovascular Imaging

Background:

  • Resuscitative clinician-performed transesophageal echocardiography (TEE) is an emerging ultrasound skill.
  • Optimal teaching methodologies for TEE remain undetermined.
  • Previous research suggests variable practice (VP) may enhance procedural skill acquisition compared to blocked practice (BP).

Purpose of the Study:

  • To compare the effectiveness of blocked practice (BP) versus variable practice (VP) for teaching resuscitative TEE to emergency medicine residents using a simulator.
  • To evaluate skill retention and transfer after a 2-week period.

Main Methods:

  • Emergency medicine residents without prior TEE experience were randomized to BP or VP training groups.
  • The BP group practiced a fixed five-view TEE sequence, while the VP group practiced varied sequences on a simulator.
  • Performance was assessed immediately post-training and via a transfer test 2 weeks later, with simulator data capturing image quality and motion metrics.

Main Results:

  • The BP group demonstrated a significantly higher percentage of successful views on the transfer test (93.6%) compared to the VP group (77.6%; p=0.002).
  • BP also resulted in superior image quality (3.3 vs. 2.9; p=0.01) and reduced probe angular motion (2982.5 vs. 4239.8 degrees; p=0.04).
  • No significant differences were found in diagnostic accuracy, confidence, or scan time between groups.

Conclusions:

  • Practicing a fixed sequence of views (blocked practice) was more effective for learning resuscitative TEE on a simulator than practicing varied sequences (variable practice).
  • These findings indicate that blocked practice may be a superior training strategy for acquiring foundational TEE skills in an simulated environment.
  • Further validation in clinical settings is recommended to confirm these results.
