Adult Echocardiography Practice Exam

In echocardiography, which transducer position is typically used to assess the left ventricle?

1. Suprasternal

2. Apical

3. Abdominal

4. Subcostal

The correct answer is: Apical

The apical transducer position is the most commonly used approach to assess the left ventricle in echocardiography. This position allows for a comprehensive evaluation of the left ventricle’s size, wall motion, and overall function. When the transducer is placed at the apex of the heart, typically at the fifth intercostal space at the midclavicular line, it offers a clear view of the left ventricle in multiple imaging planes, such as the apical four-chamber view, which visualizes all four cardiac chambers simultaneously and provides crucial information about both systolic and diastolic function. In contrast, the suprasternal position primarily focuses on the aortic arch and great vessels rather than the heart’s chambers. The abdominal position is more suitable for assessing structures below the diaphragm, such as abdominal organs and inferior vena cava, rather than the left ventricle. The subcostal position, while useful in certain situations, is generally not the first choice for detailed left ventricular evaluation, as it may not provide as optimal a view as the apical position. Overall, the apical position is favored for its direct and clear imaging of the left ventricle, thereby making it the correct choice for this question.
