Imaging Studies for Cardiovascular System II:Types of Echocardiography01:20

Imaging Studies for Cardiovascular System II:Types of Echocardiography

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 diagnosing...

Area of Science:

  • Anesthesiology
  • Hematology
  • Medical Device Technology

Background:

  • Point-of-care testing is crucial for rapid clinical decisions.
  • Accurate blood coagulation monitoring is vital in surgical and critical care settings.
  • Thromboelastography offers a comprehensive assessment of hemostasis.

Purpose of the Study:

  • To evaluate the TEG thromboelastograph and ROTEM thromboelastometer.
  • To compare ease of use, complexity, and cost between the two devices.
  • To gather user feedback from clinical specialists.

Main Methods:

  • A one-week comparative evaluation of TEG and ROTEM devices.
  • Training of consultant and trainee anaesthetists and a haematologist by manufacturers.
  • System setup, calibration, and usage by trained personnel.
  • Data collection via questionnaires on user experience and technical support.

Main Results:

  • Both TEG and ROTEM are point-of-care blood coagulation monitoring systems.
  • Devices exhibit differences in operational complexity and user-friendliness.
  • Variations exist in the initial purchase and ongoing running costs between TEG and ROTEM.

Conclusions:

  • TEG and ROTEM are comparable point-of-care coagulation devices with distinct usability profiles.
  • Cost-effectiveness and specific clinical workflow needs should guide device selection.
  • Further investigation into long-term performance and support is warranted.
