Adult Echocardiography Practice Exam

During pregnancy, there are significant physiological changes that occur in a woman's body, particularly affecting the cardiovascular system. One of the most notable changes is the increase in blood volume, which can be as much as 30-50% above pre-pregnancy levels. This increase in blood volume is essential for supporting fetal development and preparing for the demands of labor and delivery.

As a result of this increased blood volume, echocardiographic findings typically show alterations in cardiac dimensions and function. These changes include an increase in left ventricular volume, wall thickness, and overall size to accommodate the higher blood flow requirements. Additionally, there's typically an increase in stroke volume and cardiac output to meet the metabolic demands of both the mother and the developing fetus.

In summary, the correct understanding emphasizes that pregnancy results in physiological changes reflected in echocardiographic findings, particularly through adaptations in cardiac dimensions and function due to increased blood volume.
