Basic Transthoracic Echocardiography (Cardiac Ultrasound) - TTE Made Simple
POCUS 101・2 minutes read
Basic trans thoracic echocardiography includes various imaging windows and pathologies, with probe positioning and mode selection being crucial for accurate assessment. Differentiating between pericardial and pleural effusions, estimating ejection fraction, and evaluating IVC measurements are essential in guiding fluid management and making critical patient care decisions.
Insights
- Proper probe positioning and mode selection are crucial in trans thoracic echocardiography, with standard mode indicating the patient's right hip and cardiac mode pointing to the right shoulder, ensuring accurate imaging and diagnosis.
- Utilizing echocardiography for fluid management involves assessing IVC measurements, including diameter changes and the collapsibility index, to guide appropriate fluid administration based on CVP levels, ultimately aiding in patient care decisions and optimizing preload reserve.

Recent questions
What is the probe of choice for basic trans thoracic echocardiography?
The cardiac probe, also known as the phased array probe, is the preferred probe for basic trans thoracic echocardiography.
How is the indicator positioned in standard mode for echocardiography?
In standard mode, the indicator is on the left of the screen, with the probe marker pointing to the patient's right hip in a long AIS view.
What is the first step in obtaining cardiac views during echocardiography?
The first step in obtaining cardiac views is the parasal long axis view, followed by rotating the probe for short axis and apical four chamber views.
How can ejection fraction be estimated during echocardiography?
Ejection fraction can be estimated visually or quantitatively using E Point Septal Separation (EPSS) during echocardiography.
How can pericardial effusion and pleural effusion be differentiated during echocardiography?
Pericardial effusion and pleural effusion can be differentiated by specific ultrasound markers indicating each condition, with the presence of RV collapse and symptoms of hypoperfusion indicating pericardial effusion.
