Final answer:
Right-sided contrast echocardiography focuses on the right side of the heart and pulmonary circulation, while left heart contrast echocardiography focuses on the left side of the heart and systemic circulation.
Step-by-step explanation:
Right-sided contrast echocardiography and left heart contrast echocardiography are two different types of contrast echocardiograms that focus on different areas of the heart. Right-sided contrast echocardiography involves injecting a contrast agent into the right side of the heart to assess the function and structure of the right atrium and ventricle, as well as the pulmonary circulation. Left heart contrast echocardiography, on the other hand, involves injecting a contrast agent into the left side of the heart to assess the function and structure of the left atrium and ventricle, as well as the systemic circulation.
When performing right-sided contrast echocardiography, the contrast agent is injected into the right atrium and then flows into the right ventricle and pulmonary arteries. This allows for the visualization of the pulmonary circulation and the detection of any abnormalities or blood clots. On the other hand, left heart contrast echocardiography involves injecting the contrast agent into the left atrium, allowing for the visualization of the left ventricle, aorta, and systemic circulation.
