echocardiography

List the four chambers of the heart. Which receives blood from the body? Which receives blood from the lungs? - ANS These are the left atrium, the left ventricle, right atrium, and right ventricle. The right atrium receives blood from the body (IVC CVC CS), while the left atrium receives blood from the lungs (4 pulmonary veins). Which chamber sends blood to the body? Which chamber sends blood to the lungs? - ANS The left ventricle sends blood to the body, and the right ven...

What does partial closure of the aortic valve in mid-systole suggest? This is a classic feature of subvalvular obstruction caused by either the dynamic gradient of HCM or fixed obstruction of a subaortic membrane How can you distinguish aortic stenosis flow from MR or TR flow on continuous wave doppler? Look for the abrupt bright spikes in the CW spectral Doppler signal. Aortic stenosis flow should only start after the aortic valve opens Name a condition in which the modified Bernou...

What is the normal value for coronary flow reserve? 4 What does this mean? Flow can increase 4-fold in response to vasodilators, such as adenosine. What is TAPSE? What does it indicate? Tricuspid Annular Plane Systolic Excursion is an indication of RV function with better inter- and intraobserver accuracy than wall motion. How can TAPSE be measured by TEE? TAPSE can be measured in 2D or MMode. What is the normal value for TAPSE? > 20 mm What is another use for TA...
