Adult Echocardiography (AE) study guide
Adult Echocardiography (AE) · Work through your exam, one topic at a time.
The Registered Diagnostic Cardiac Sonographer (RDCS) credential is one of the four ARDMS credentials, and ARDMS is described in its own materials as "an Inteleos member community" that has, in its words, set standards for sonography since 1975 - "certification by sonographers, for sonographers." Adult Echocardiography is the RDCS specialty exam for sonographers and physicians who perform and interpret echocardiograms on adult patients, and it is listed by ARDMS alongside Fetal, Pediatric, and other cardiovascular specialties. Because Inteleos describes itself as offering four credentials across eleven unique specialties, candidates should treat Adult Echo as one specialty track rather than a stand-alone certificate. The Adult Echocardiography (AE) study guide has 5 sections and about 1,438 words.
01Cardiac Anatomy and Physiology: Chambers, Segments, and the Cardiac Cycle
Begin with the fibrous skeleton: the aortic valve sits centrally, the anterior mitral leaflet is continuous with the aortic root, and this relationship explains why root disease can produce mitral pathology. The LV is a truncated ellipsoid whose subendocardial fibers run longitudinally - they are the first to fail in ischemia, which is why longitudinal strain drops before ejection fraction does.

Sound travels at approximately 1540 m/s in soft tissue. Higher frequency means shorter wavelength, better axial resolution, and worse penetration - the central trade-off behind most physics items.

Acquisition items test whether you know which window answers which question. Parasternal long axis: LV dimensions, aortic root, valve morphology, pericardial effusion, and the LVOT diameter.

Valve questions reward a systematic approach. Aortic stenosis: integrate peak velocity, mean gradient, continuity-derived area (AVA = 0.785 × D² × VTI LVOT ÷ VTI AV), and dimensionless index (VTI ratio <0.25 indicates severe).

Hypertrophic cardiomyopathy: asymmetric septal hypertrophy ≥15 mm (≥13 mm in relatives), systolic anterior motion of the mitral leaflet, dynamic LVOT obstruction (gradient ≥30 mmHg at rest or with provocation), mid-systolic aortic valve notching, and apical hypertrophy with a spade-shaped cavity. Dilated cardiomyopathy: LV dilatation with EF <45%, global hypokinesis, and functional regurgitation.
