FREE ARDMS RDCS Pediatric Echo Exam Guide 2026 (PE)

ARDMS RDCS Pediatric Echocardiography Exam Guide 2026: Pass the PE on the First Attempt

The ARDMS Registered Diagnostic Cardiac Sonographer (RDCS) with the Pediatric Echocardiography (PE) specialty is the dominant credential for pediatric cardiac sonographers in the United States and Canada. It is what IAC-accredited pediatric echo labs, children's hospitals, academic medical centers, and pediatric cardiology groups ask for — and the near-universal requirement for a lead pediatric echo tech role or a traveling pediatric cardiac sonographer assignment.

This guide treats the PE exam the way high-scoring candidates actually do: as a segmental analysis + congenital heart disease pattern recognition challenge on top of pediatric-specific Z-score measurement discipline, filtered through SPI Doppler physics. By the end of this page you will know exactly what the exam tests, which prerequisite path fits your background, what CHD anatomy and Z-scores to memorize cold, and how to pace a realistic 12-16 week prep around the Windowed PE schedule.

RDCS PE Exam At-a-Glance (SPI + Pediatric Echo Structure)

The RDCS PE credential is not a single exam. It is a two-exam pathway through ARDMS.

You earn the RDCS (PE) when you have passed both exams AND ARDMS has verified your prerequisite pathway documentation. If PE was passed first, you have 5 years from that date to complete SPI. If SPI was first, you have 5 years from SPI to complete PE. Adding PE to an existing RDCS AE credential does not require a repeat SPI as long as Active Status is maintained — you only take the PE specialty.

The SPI + PE Two-Exam Requirement

The #1 concept new candidates misunderstand: you cannot earn RDCS PE by passing only one exam. ARDMS requires two separate, independently scored exams.

1. SPI (Sonography Principles & Instrumentation) — the universal physics prerequisite for every ARDMS specialty. Covers sound propagation, transducer design, pulsed vs continuous wave Doppler, aliasing and the Nyquist limit, spectral analysis, power/intensity, artifacts, and instrumentation controls.
2. Pediatric Echocardiography (PE) specialty — clinical pediatric cardiac ultrasound, including congenital heart disease (repaired and unrepaired), pediatric cardiomyopathy, Kawasaki disease, rheumatic disease, pediatric Z-score measurements, and fetal echo basics.

Rule of thumb: SPI material is directly reusable on PE — roughly 10-15% of PE items are physics-adjacent (high-frequency transducer selection for neonates, Nyquist management in high-velocity shunts, harmonic imaging for contrast, TI/MI pediatric safety limits). Studying SPI first and taking PE second is the cleanest path for most candidates, especially because PE is Windowed: wasting a rare PE window on physics gaps is a costly mistake.

If you already hold RDCS AE, your SPI pass transfers automatically — you only register for the PE specialty.

Prerequisite Paths (Shared with Adult Echo)

ARDMS PE prerequisite rules mirror the Adult Echocardiography paths, with the clinical experience emphasis shifted to pediatric cardiac ultrasound. Below are the 2026 pathways. Always confirm against the current ARDMS Examination Applicant Prerequisites and Examination Requirements document before submitting your application.

Prerequisite 1: Allied Health Education + 12 Months Pediatric Cardiac Experience

• Complete a 2-year patient-care-related allied health education program (RT, RRT, RDH, paramedic, RN associate, etc.).
• Accumulate 12 months of full-time clinical pediatric cardiac ultrasound experience (1,680 hours over 48+ weeks).
• Documentation: transcript, Clinical Verification (CV) form, CV narrative, government-issued ID.

Prerequisite 2: CAAHEP/CMA-Accredited DCS or DMS Program

• Graduate of (or current student 60 days prior to graduation) in a CAAHEP-accredited (US) or CMA-accredited (Canada) diagnostic cardiac sonography or DMS program, with pediatric rotations documented.
• Program director verification letter required.
• Note: many DCS programs emphasize adult echo; if your rotations were adult-heavy, add documented pediatric case hours before applying for PE.

Prerequisite 3A: Bachelor's Degree (Any Major) + 12 Months Pediatric Cardiac Experience

• Bachelor's degree in any field (or foreign equivalent).
• 12 months of full-time clinical pediatric cardiac ultrasound experience (1,680 hours over 48+ weeks).
• Documentation: official transcript or foreign equivalency report, letter, CV form, ID.

Prerequisite 3B: Bachelor's Degree in Sonography or Cardiac Sonography

• Graduate of (or student in) a bachelor's in sonography or cardiac sonography program with pediatric clinical rotations.
• No additional experience required beyond program curriculum, but pediatric hours must be documented.

Prerequisite 5: Active RDCS AE, CCI RCCS, or ARRT Equivalent

• Hold an active RDCS (AE), CCI RCCS (Registered Congenital Cardiac Sonographer), or applicable ARRT credential in good standing.
• Documentation: copy of current credential in good standing, ID.
• Fastest pathway for already-credentialed cardiac sonographers crosswalking into pediatric.

Physician Prerequisite: MD/DO/MBBS + 500 Cases

• MD, DO, or MBBS (US or foreign equivalent).
• Minimum of 500 clinical diagnostic pediatric echocardiographic studies over a minimum of 6 months.
• Physician applications route through APCA (Alliance for Physician Certification & Advancement).

Documentation rule: ARDMS rejects incomplete applications outright and does not refund application fees beyond the $100 processing fee. For PE specifically, because the exam is Windowed, a rejected application can delay your credential by 6+ months — assemble your transcript, CV form, and pediatric case log as a single PDF packet and apply well before your target window.

PE Content Deep Dive: What the Exam Actually Tests

The Pediatric Echocardiography outline weights five domains: Anatomy & Physiology, Pathology (congenital + acquired), Clinical Care & Safety, Measurement Techniques and Pediatric Sonographic Views, and Instrumentation/Optimization/Contrast. Pathology is the largest single domain — and within pathology, congenital heart disease is the majority of your score.

Pediatric Imaging Planes — What's Different from Adult

Children have thinner chest walls, smaller hearts, and faster heart rates — which changes frame-rate demands, transducer selection (high-frequency phased array 8-12 MHz for neonates; 5-8 MHz for older children), and Doppler settings. Expect items on high-frequency phased-array selection, frame rate optimization for neonatal heart rates >140 bpm, and harmonic imaging trade-offs in small patients.

Segmental Analysis — The Pediatric Echo Backbone

Segmental analysis is the systematic step-by-step approach to any pediatric heart and is the foundation of every CHD diagnosis. Every high-scoring PE candidate can recite it in order, in sleep:

1. Situs — solitus (normal), inversus, or ambiguus (heterotaxy). Check abdominal situs (IVC/aorta position), cardiac position (levocardia, dextrocardia, mesocardia), and atrial appendages.
2. Atrioventricular (AV) connections — concordant (RA-RV, LA-LV), discordant (RA-LV, LA-RV = L-looped), ambiguous (single AV valve, common AV valve = AVSD), or absent (tricuspid or mitral atresia).
3. Ventriculoarterial (VA) connections — concordant (RV-PA, LV-Ao), discordant (RV-Ao, LV-PA = TGA), double-outlet right ventricle (DORV), double-outlet left ventricle, or single outlet (truncus, pulmonary atresia).
4. Associated anomalies — VSD location and size, ASD type, PDA, coarctation, pulmonary/aortic stenosis, anomalous veins, coronary anomalies.

Expect 15-25 items that require segmental-analysis thinking — including hotspot items asking you to click the AV valve that is straddling or to identify the great vessel arising from the morphologic right ventricle.

Congenital Heart Disease You Must Know Cold

Below are the high-yield CHD lesions by frequency on the exam. For each, know: embryologic origin, 2D anatomy, flow pattern, hemodynamic consequences, and surgical repair(s).

Shunt Lesions (Left-to-Right)

• ASD — secundum (most common, fossa ovalis region), primum (part of AVSD spectrum, inferior atrial septum), sinus venosus (superior — near SVC; or inferior — near IVC; often with anomalous pulmonary venous return), coronary sinus unroofed. RV volume overload. Best views: subcostal 4-chamber + high RV inflow.
• VSD — perimembranous (most common), muscular, inlet (AVSD), outlet/conal/subarterial (risk of AR from AV cusp prolapse). Describe by location, size (small <1/3 aortic diameter, moderate, large ≥ aortic diameter), and pressure gradient. Maladie de Roger = small restrictive VSD.
• PDA — persistent ductus arteriosus between descending aorta distal to left subclavian and main PA at the LPA origin. Left-to-right continuous flow (LA/LV volume overload). Imaging: high parasternal short-axis / ductal cut, SSN.
• AVSD (endocardial cushion defect) — complete (primum ASD + inlet VSD + common AV valve), partial (primum ASD + cleft mitral valve), transitional (partial with small inlet VSD). Common in Down syndrome. Look for the loss of normal AV valve offset (apical 4-chamber).

Obstructive Lesions

• Pulmonary stenosis — valvar (most common, doming leaflets), subvalvar, supravalvar, branch PA. Poststenotic dilation of MPA. Critical PS in neonate = ductal-dependent.
• Aortic stenosis — valvar (often bicuspid or unicuspid in neonates), subaortic membrane, supravalvar (Williams syndrome — hourglass narrowing above AV). Watch for LV hypertrophy and post-stenotic dilation.
• Coarctation of the aorta — juxtaductal narrowing at aortic isthmus. SSN long-axis shows discrete shelf; CW Doppler shows continuous diastolic flow ("sawtooth"). Often with bicuspid AV. In neonates, ductal-dependent systemic circulation.
• Interrupted aortic arch — type A (distal to LSCA), type B (between LCCA and LSCA — most common, assoc. with 22q11 DiGeorge), type C (between innominate and LCCA). Ductal-dependent.

Cyanotic CHD

• Tetralogy of Fallot (TOF) — embryologic: anterior malalignment of the conal septum. Four features: large malalignment VSD, overriding aorta, RVOT obstruction (infundibular ± valvar PS), RV hypertrophy. PLAX shows aorta overriding a large VSD; PSAX shows RVOT/PS.
• TOF vs DORV — a classic distinction. TOF = aorta overrides the VSD but is primarily committed to the LV (<50% override). DORV = >50% of both great vessels arise from the RV, and the VSD may be sub-aortic, sub-pulmonary (Taussig-Bing), doubly committed, or non-committed. Both can have PS; segmental approach resolves the distinction.
• Transposition of the great arteries (d-TGA) — VA discordance: aorta from RV, PA from LV. Parallel circulations; ductal- and atrial-level mixing keep the neonate alive until arterial switch (Jatene) operation. PLAX shows parallel great arteries; PSAX at the base shows the classic "circle and sausage" side-by-side pattern.
• Hypoplastic left heart syndrome (HLHS) — hypoplastic LV, mitral and/or aortic atresia/stenosis, hypoplastic ascending aorta. Ductal-dependent systemic circulation. Staged surgical palliation: Norwood (Stage 1) → Glenn (Stage 2) → Fontan (Stage 3).
• Tricuspid atresia — absent RV inflow (TV atresia); obligatory ASD; variable VSD; hypoplastic RV; single-ventricle physiology. Fontan pathway.
• Ebstein anomaly — apical displacement of the septal and posterior TV leaflets (> 8 mm/m² from the MV insertion on A4C). Atrialized RV, severe TR, RA enlargement. Associated with WPW and ASD.
• Single-ventricle physiology — tricuspid atresia, HLHS, unbalanced AVSD, double-inlet LV, severe Ebstein — all pool to the same staged palliation pathway.

Anomalous Venous Return

• TAPVR (total anomalous pulmonary venous return) — supracardiac (to innominate or SVC), cardiac (to CS or RA), infracardiac (to portal vein or ductus venosus — obstructed, neonatal emergency), mixed. All pulmonary veins drain to the systemic venous circulation; obligatory ASD/PFO.
• PAPVR (partial) — one or more (but not all) pulmonary veins drain anomalously. Often with sinus venosus ASD (RUPV → SVC-RA junction).

Pediatric Pulmonary Artery & Aortic Arch Variants

• Right aortic arch — with mirror-image branching (often TOF, truncus) or aberrant left subclavian (vascular ring potential).
• Double aortic arch — vascular ring; tracheal and esophageal compression.
• Pulmonary artery sling — LPA arising from the RPA, coursing between trachea and esophagus; vascular sling.
• Branch PA stenosis — often postoperative (TOF repair, arterial switch LeCompte maneuver).

Postoperative CHD Circulations

You must recognize the hemodynamic signature of each palliation — these are workhorse items.

• Norwood (Stage 1 for HLHS): neo-aorta reconstructed from native PA root + ascending aorta; atrial septectomy; pulmonary flow via a modified Blalock-Taussig-Thomas (BTT) shunt or a Sano RV-to-PA conduit. Echo: neoaortic root with connected PA trunks; BTT shunt flow continuous; single ventricle is the RV.
• Glenn (Stage 2, bidirectional cavopulmonary anastomosis): SVC anastomosed end-to-side to the RPA; IVC still drains to the single atrium. Lower body deoxygenated blood bypasses the lungs. Echo: look at SVC-to-RPA anastomosis in SSN and high parasternal views.
• Fontan (Stage 3, total cavopulmonary connection): IVC connected to the PA (extracardiac conduit or lateral tunnel). Passive pulmonary flow — no ventricle pumps blood to the lungs. Fontan hemodynamics depend on low pulmonary vascular resistance and competent AV valve function. Complications: Fontan-associated liver disease, plastic bronchitis, protein-losing enteropathy, atrial arrhythmias.
• Arterial switch (Jatene) for d-TGA: great arteries transected above sinuses and switched; coronaries reimplanted; LeCompte maneuver brings branch PAs anterior to the neoaorta. Watch for branch PA stenosis and neoaortic root dilation with AR.
• Rastelli / REV / Nikaidoh: for d-TGA with VSD and LVOT obstruction — routes LV through VSD to aorta via intraventricular baffle, with RV-to-PA conduit.
• Ross procedure: native pulmonary autograft replaces a diseased aortic valve; homograft replaces the PA valve. Two valves to watch postoperatively.

Pediatric Cardiomyopathies

• Hypertrophic (HCM) — familial sarcomere mutations most common in pediatrics; can present with severe neonatal HCM (Noonan, Pompe, RASopathies). Assess LV wall thickness Z-score, LVOT gradient at rest and with provocation, SAM.
• Dilated (DCM) — often post-myocarditis, neuromuscular (Duchenne), mitochondrial, or idiopathic. LV dilation, reduced EF, secondary MR.
• Restrictive (RCM) — rare; biatrial enlargement with normal-size ventricles; restrictive diastolic filling.
• LV non-compaction — prominent trabeculations with deep recesses; non-compacted:compacted ratio > 2:1 at end-systole.
• Arrhythmogenic RV cardiomyopathy (ARVC) — RV dilation and regional wall motion abnormalities; rarely seen in young children.
• Myocarditis — acute LV dysfunction, regional or global hypokinesis, pericardial effusion; often post-viral.

Kawasaki Disease & Coronary Aneurysms

Kawasaki disease (KD) is an acquired childhood vasculitis with a predilection for coronary arteries. Coronary Z-score classification is testable material.

Imaging: measure proximal LMCA, proximal LAD, proximal RCA at standard locations in PSAX aortic valve level and apical views; use BSA-indexed Z-scores (Dallaire/Boston). Giant aneurysms carry the highest thrombosis/stenosis risk and require long-term surveillance echo plus anticoagulation.

Pediatric Myocardial Function — Strain and TDI

Pediatric echo relies more heavily on strain imaging and tissue Doppler imaging (TDI) than adult echo, because fractional shortening and Simpson's EF are unreliable when the RV is a workhorse (single-ventricle physiology) or when geometry is abnormal (post-Fontan, TOF repair).

• Global Longitudinal Strain (GLS) — normal approximately −20% in healthy children (slightly more negative than adults in many age groups); abnormal at ≥ −16%. Used for cardiotoxicity surveillance (oncology), sickle cell, Duchenne, Fontan surveillance.
• Tissue Doppler imaging (TDI) — myocardial velocities are age-dependent. Z-scores for S', E', A' at the mitral, tricuspid, and septal annuli must be used — do not apply adult cutoffs.
• E/e' ratio — similarly age-indexed; adult thresholds (E/e' > 14 = elevated) do not directly apply to pediatric patients.
• Single-ventricle function — GLS and 3D EF are preferred because geometry is not a left ventricle.

Boston Z-Score Calculators — The Workhorse Tool

The Pediatric Heart Network (PHN) and Boston Children's Hospital Z-score calculators are the field-standard references and are testable content. You do not need to memorize every formula, but you must know:

• All pediatric cardiac dimensions are indexed to body surface area (BSA) using Haycock or Dubois formulas.
• Common Z-scored structures: aortic root (annulus, sinus of Valsalva, sinotubular junction, ascending aorta), mitral and tricuspid annulus, LV end-diastolic and end-systolic dimensions, RV size, main PA and branch PAs, coronary arteries (LMCA, LAD, RCA).
• Threshold rule: Z ≥ 2.0 is abnormal (>2 standard deviations above mean); Z ≥ 2.5 borderline dilation; Z ≥ 5 overt dilation; Z ≥ 10 severe/aneurysmal.
• The specific calculator matters — Boston vs Detroit vs Pediatric Heart Network produce slightly different Z-scores because of cohort differences. Lab SOPs dictate which to use; the exam expects you to know that lab standardization matters.

Fetal Echocardiography Basics (within PE)

Fetal echo content on the PE exam is introductory — deep fetal content lives in RDCS FE. Expect items on:

• Standard fetal cardiac views (ISUOG/AIUM): situs, 4-chamber, LVOT (5-chamber), RVOT, 3-vessel view (3VV) (PA, Ao, SVC left-to-right), 3-vessel-trachea view (3VT) (PA, ductus, arch, SVC with trachea reference — "V-sign" of ductal + aortic arches).
• Aortic and ductal arch views (sagittal): arch sweep showing candy-cane aortic arch with head-and-neck vessels, and hockey-stick ductal arch.
• Bicaval view: IVC/SVC drainage into RA.
• Flow directions: ductus arteriosus and foramen ovale right-to-left in normal fetal circulation.
• Prenatal diagnoses with classic appearance: HLHS (small LV, retrograde arch flow), TGA ("I" sign parallel outflows on 3VV), coarctation (discordant ventricular sizes with RV > LV and small arch), AVSD (loss of AV valve offset, single AV valve), Ebstein (severe TR, apical TV displacement), TAPVR (no pulmonary veins into LA, confluence behind LA), heterotaxy (abdominal situs abnormal).

Cost Stack (SPI + PE)

Budget the full RDCS PE credential, not just one exam.

Budget total to credential: ~$550 if both exams pass on first attempt (SPI $250 + PE $300). Add ~$300 for each PE retake. Many employers reimburse exam fees — confirm with HR before paying.

Registration via Pearson VUE

1. Create an ARDMS account at ardms.org and complete the online exam application. Upload your documentation packet (transcript, CV form, ID).
2. Pay the application + exam fee. Processing takes 10-15 business days; incomplete packets trigger a Request for Additional Information and delay review.
3. Upon approval you receive an Examination Confirmation Letter (ECL). For PE you must schedule and test within the active PE administration window published by ARDMS (January and spring 2026 windows closed; next PE application period reopens July 21, 2026, with administration running July 21 - November 5, 2026).
4. Schedule at Pearson VUE (pearsonvue.com/ardms). Choose a test center; PE is in-person only at Pearson VUE — there is no online proctored delivery for PE.
5. Bring two valid IDs (one government-issued photo) matching your ECL exactly. Arrive 30 minutes early.

For scheduling changes: Pearson VUE allows rescheduling up to 24 hours prior to the exam for a fee. Cancellations and no-shows forfeit the exam fee.

CME Recert: MOC After January 2026

ARDMS modernized its Maintenance of Certification (MOC) program effective January 1, 2026. The structure:

1. Knowledge Confirmation (KC) quizzes — new annual requirement. All active certificants complete four short specialty-specific KC quizzes each year on the SKILLS Platform (quizzes released quarterly). First set due December 31, 2026. PE holders take PE-specific KC quizzes; dual RDCS AE + PE holders take KC quizzes for each specialty.
2. Reduced CME load. 25 ARDMS/APCA-accepted CME credits per 3-year cycle (reduced from 30 to offset the KC component) for CME periods ending December 31, 2026 and beyond, submitted by December 31.
3. Annual attestation + renewal fee. $105/year for RDCS (same flat fee as RDMS, RVT, and RMSKS) by December 31.
4. No more decennial reexamination for active-status sonographers in good standing. Lapsed credentials require retaking BOTH SPI and the PE specialty exam.

Accepted CME sources: ARDMS.org, APCA, ASE (American Society of Echocardiography), SDMS, ACPC (Alliance for Pediatric Cardiology Continuing education), pediatric cardiology hospital grand rounds (with accreditation), and peer-reviewed journal clubs formatted as AMA PRA Category 1.

Test-Day Strategy

• Arrive 30 minutes early at your Pearson VUE test center. Late arrival >15 minutes forfeits the exam with no refund.
• Bring two forms of ID, one government-issued photo with signature, matching the name on your ECL exactly.
• No personal items in the testing room: no phone, watch, notes, food, drink, hat. Pearson VUE lockers are provided.
• The computer provides an on-screen calculator (basic four-function). Practice mental math for Z-score ranges and Bernoulli anyway.
• Time budget: 3 hours for 145 items = ~74 seconds per item (roughly 1 min 14 sec). Mark-and-return is available.
• Hotspot items on cine loops and segmental anatomy — expect roughly 15-20 of them. Practice clicking the correct valve, vessel, or measurement point before test day.
• Pacing trap: candidates burn minutes on a single tough congenital cine loop. Flag, best-guess, move on, come back at the end.
• Score release for PE is NOT at the test center. Because PE is a Windowed exam, ARDMS releases examination results and a full score report approximately 60 days after the close of the administration window — plan emotionally and logistically for the wait.

Common Pitfalls (and Fixes)

---

Career Value: Pediatric Sonographer + RDCS PE Differential

The RDCS PE credential unlocks roles that are almost exclusively based at tertiary pediatric cardiology programs, academic children's hospitals, and dedicated pediatric cardiology group practices. Because the talent pool is small — far smaller than adult echo — RDCS PE sonographers consistently command premium compensation.

• Pediatric cardiac sonographer (staff, 0-5 years experience): $75,000 - $95,000 at most US children's hospitals.
• Senior / lead pediatric echo tech (5-10 years): $95,000 - $120,000 at academic children's hospitals (Boston Children's, CHOP, Texas Children's, CCHMC, Seattle Children's, Lurie, Nemours, Children's National).
• Dual-credentialed RDCS AE + PE + FE: the most versatile pediatric cardiology sonographer, regularly $110,000+ and rapid advancement to lead tech roles.
• Travel pediatric cardiac sonographer: $2,800 - $4,000/week gross — a small but premium market driven by shortages at regional children's centers.
• Fetal cardiac sonographer (with RDCS FE): maternal-fetal medicine and pediatric cardiology hybrid positions with equally strong compensation.

Why the premium? Pediatric cardiology labs run high-complexity workflows: neonatal ICU bedside echoes, intraoperative monitoring, cath lab support, Fontan surveillance, fetal consults, and outpatient CHD follow-up. Hospitals budget accordingly.

Per the U.S. Bureau of Labor Statistics Occupational Outlook Handbook (SOC 29-2032), median annual wage for the broader CVT category was roughly $67,260 in May 2024 with 3% projected growth through 2034 — but the pediatric subspecialty sits well above the blended median.

Cities with the largest pediatric cardiac sonographer demand (2024-2026 hiring data): Boston, Philadelphia, Washington DC, Cincinnati, Houston, Dallas, Chicago, Los Angeles, Seattle, and other markets with freestanding children's hospitals.

RDCS AE vs RDCS PE vs RDCS FE — Which Track?

Practical strategy by background:

• DCS grad with adult rotations only: RDCS AE first (On Demand), accumulate pediatric hours, then PE.
• DCS grad with pediatric rotations: RDCS PE directly if prerequisites met; many programs recommend AE first for breadth.
• Current pediatric sonographer without credentials: RDCS PE first (core job credential), add AE later for breadth.
• Fetal/MFM sonographer pivoting: RDCS FE via RDMS or RDCS (choose deliberately — once declared the credential area cannot be switched).
• Already RDCS AE: PE requires only the PE specialty exam — SPI transfers while Active Status is maintained.

Important: FE may be pursued under either RDMS or RDCS. Once you apply under one credential area, it cannot be switched — choose deliberately. RDCS FE is the more common choice for cardiac-trained sonographers; RDMS FE is the path for OB/GYN sonographers expanding into fetal cardiac.
