CVT Echocardiography Techniques 3

Question 1

In the modified Simpson's biplane method for ejection fraction calculation, images from which two views are required?

Accepted Answer

Apical four-chamber and apical two-chamber

Answer

Simpson's biplane method requires tracing the left ventricular cavity in both the apical four-chamber and apical two-chamber views.

Question 2

Which echocardiographic finding is most characteristic of cardiac tamponade on two-dimensional imaging?

Accepted Answer

Right ventricular diastolic collapse

Answer

Right ventricular diastolic collapse occurs when pericardial pressure exceeds right ventricular diastolic pressure, indicating hemodynamically significant tamponade.

Question 3

The proximal isovelocity surface area (PISA) method estimates regurgitant volume by analyzing which flow phenomenon?

Accepted Answer

Hemispheric flow convergence proximal to the regurgitant orifice

Answer

PISA measures the radius of the hemispheric flow convergence zone proximal to the regurgitant orifice to calculate effective regurgitant orifice area.

Question 4

Which transesophageal echocardiographic (TEE) view is optimal for evaluating the left atrial appendage for thrombus?

Accepted Answer

Mid-esophageal two-chamber view at 60–90°

Answer

The mid-esophageal two-chamber view at 60–90° provides the best visualization of the left atrial appendage due to its proximity to the esophagus.

Question 5

Which Doppler pattern of mitral inflow indicates Grade III (reversible restrictive) diastolic dysfunction?

Accepted Answer

E/A ratio > 2 with deceleration time < 160 ms that normalizes with Valsalva

Answer

Grade III reversible restrictive filling shows E/A > 2 with shortened deceleration time that reverts to a lower E/A ratio during Valsalva maneuver.
