✍️ Sample ARDMS ECHO Questions & Answers

1. The RVOT acceleration time (AT) is used to estimate mean pulmonary artery pressure. Which formula applies?

✓ mPAP = 79 − (0.45 × AT)

mPAP ≈ 79 − (0.45 × RVOT AT in ms) is a validated formula; shorter AT corresponds to higher pulmonary artery pressure.

2. What is the advantage of using transesophageal echocardiography (TEE) over transthoracic echocardiography (TTE)?

✓ TEE provides clearer images of posterior cardiac structures

Transesophageal echocardiography (TEE) offers a significant advantage over transthoracic echocardiography (TTE) by providing superior image quality, particularly for posterior cardiac structures. Placing the transducer in the esophagus positions it much closer to the heart, bypassing the ribs, lungs, and chest wall. This proximity and lack of acoustic impedance result in higher resolution images, which are crucial for evaluating structures like the left atrium, mitral valve, and aorta.

3. What does the velocity-time integral (VTI) of the LVOT represent?

✓ Stroke distance (distance blood travels per beat)

LVOT VTI represents the stroke distance — the column of blood ejected per heartbeat — and when multiplied by LVOT CSA gives stroke volume.

4. What is the most common etiology of isolated severe tricuspid regurgitation in the United States?

✓ Functional (secondary to RV dilation/annular dilation)

Functional TR caused by RV dilation and tricuspid annular dilation (from pulmonary hypertension or LV dysfunction) is the most common cause of severe TR in the US.

5. Which parameter best differentiates severe mitral regurgitation from moderate on echocardiography using the PISA method?

✓ EROA ≥ 0.40 cm² and regurgitant volume ≥ 60 mL

Severe primary MR criteria include EROA ≥0.40 cm² and regurgitant volume ≥60 mL per ASE/AHA/ACC guidelines.

6. A ventricular septal defect (VSD) with left-to-right shunt produces which hemodynamic finding on echo?

✓ LV and LA volume overload

Left-to-right VSD shunting causes increased pulmonary flow returning to the left heart, resulting in LV and LA volume overload.
