  1. Which finding on a standard echo report is most consistent with cardiac amyloidosis?

    Answer: Concentric biventricular hypertrophy with a sparkling or granular myocardial texture and diastolic dysfunction

    Cardiac amyloidosis classically shows concentric LV and RV hypertrophy, granular/sparkling myocardial appearance, diastolic dysfunction, and small LV cavity with preserved or mildly reduced EF.

  2. What does a 'relative wall thickness (RWT)' of >0.42 with increased LV mass indicate?

    Answer: Concentric LV hypertrophy

    RWT = (2 × posterior wall thickness) / LVEDD; RWT >0.42 with increased LV mass = concentric hypertrophy; RWT >0.42 with normal mass = concentric remodeling.

  3. In an echo report describing valvular disease, 'effective regurgitant orifice area (EROA) ≥0.40 cm²' for mitral regurgitation indicates:

    Answer: Severe MR

    Per ASE guidelines, EROA ≥0.40 cm² (primary MR) or ≥0.20 cm² (secondary/functional MR) defines severe mitral regurgitation.

  4. Which echocardiographic finding in the report is most suggestive of non-compaction cardiomyopathy (LVNC)?

    Answer: Prominent trabeculations with deep recesses, non-compacted-to-compacted ratio >2.0 in systole

    LVNC is characterized by a two-layered myocardium with excessive trabeculations and an NC:C ratio >2.0 in systole (Jenni criteria) or >2.3 in diastole (Petersen MRI criteria adapted).

  5. The ARDMS Echo specialty credential is maintained through continuing medical education. How many continuing education credits (CEs) are required per 3-year renewal cycle?

    Answer: 30 CEs

    ARDMS requires 30 continuing education credits every 3 years for credential renewal, with specific requirements for echo-related content.

  6. Which echocardiographic finding supports a diagnosis of hypertrophic obstructive cardiomyopathy (HOCM) on a routine report?

    Answer: Asymmetric septal hypertrophy (ASH) ≥15 mm with SAM of mitral valve and LVOT gradient >30 mmHg

    HOCM is characterized by ASH (septal-to-posterior wall ratio ≥1.3–1.5), systolic anterior motion (SAM) of the mitral valve causing LVOT obstruction, and elevated resting or provokable LVOT gradient.
