Which of the following conditions is most commonly associated with left ventricular hypertrophy in echocardiography?
Aortic stenosis causes increased resistance to blood flow from the left ventricle, leading to hypertrophy of the left ventricular muscle as it works harder to pump blood through the narrowed valve.
What echocardiographic finding is typically seen in a patient with dilated cardiomyopathy?
Dilated cardiomyopathy is characterized by dilation of the left ventricle with systolic dysfunction, leading to a reduced ejection fraction, which is a key finding on echocardiography.
In echocardiography, what is the most indicative finding of a pericardial effusion?
A pericardial effusion appears as an echo-free space between the heart (epicardium) and the pericardium, indicating the presence of fluid.
Which echocardiographic feature is most commonly associated with mitral regurgitation?
Mitral regurgitation often causes retrograde blood flow into the left atrium during systole, which can lead to flow reversal in the pulmonary veins, visible on echocardiography.
What pathophysiological change is most likely to be observed in a patient with hypertrophic cardiomyopathy on echocardiography?
Hypertrophic cardiomyopathy is characterized by asymmetric hypertrophy of the interventricular septum, which is a hallmark finding on echocardiography, often associated with left ventricular outflow tract obstruction.
