CCI's RCCS exam is the congenital and pediatric counterpart to the adult-focused RCS. The exam is a multiple-choice computer-based test administered at Pearson VUE centers using a scaled 200-900 score with 700 typically required to pass. Content covers cardiac embryology and normal anatomy, segmental analysis, septal defects (ASD/VSD/AVSD), conotruncal anomalies (TOF/TGA/truncus/DORV), single-ventricle physiology and Norwood/Glenn/Fontan staging, outflow obstructions, anomalous venous/arterial connections, pediatric acquired disease (Kawasaki, rheumatic, cardiomyopathies, myocarditis), ACHD residual lesions, pediatric quantitative metrics, and ALARA/IAC professional standards. Eligibility is via clinical experience routes per the CCI candidate handbook.

1During cardiac embryogenesis, the primary heart tube undergoes 'D-looping' (rightward looping) in the normal heart. What is the developmental consequence if 'L-looping' occurs instead?

A.Atrial situs inversus with normal ventricles

B.Ventricular inversion (the morphologic right ventricle ends up on the left)

C.Persistent truncus arteriosus

D.Total anomalous pulmonary venous return

Explanation: Normal cardiac looping (D-loop, dextro) places the morphologic right ventricle on the right. L-looping (levo) reverses ventricular orientation, placing the morphologic right ventricle on the left side. In congenitally corrected transposition (ccTGA, also called L-TGA), L-looping combines with abnormal great-vessel relationships so that systemic venous blood still reaches the lungs and pulmonary venous blood still reaches the body, but the morphologic RV functions as the systemic ventricle.

2In normal fetal circulation, oxygenated blood from the placenta is shunted preferentially across which structure to supply the fetal brain?

A.Foramen ovale

B.Ductus arteriosus

C.Ductus venosus only

D.Coronary sinus

Explanation: Oxygenated blood returns from the placenta via the umbilical vein, bypasses the liver through the ductus venosus, and enters the right atrium via the IVC. The Eustachian valve directs this oxygenated stream across the foramen ovale into the left atrium, then to the LV and ascending aorta to perfuse the coronary arteries and brain. This streaming is why the fetal brain receives the most oxygenated blood available.

3Which of the following typically closes FUNCTIONALLY within the first 24-72 hours of life and ANATOMICALLY within 2-3 weeks in a healthy term newborn?

A.Foramen ovale

B.Ductus arteriosus

C.Umbilical vein

D.Falciform ligament

Explanation: The ductus arteriosus closes functionally within ~24-72 hours after birth (driven by rising PaO2 and falling prostaglandin E2) and anatomically within 2-3 weeks, becoming the ligamentum arteriosum. The foramen ovale closes functionally within hours but remains probe-patent in ~25% of adults (PFO).

4Using the segmental approach to congenital heart disease, what is the FIRST step?

A.Determine ventriculoarterial (VA) connection

B.Determine atrioventricular (AV) connection

C.Determine atrial situs (arrangement)

D.Determine the great-artery relationship

Explanation: The segmental approach proceeds in order: (1) atrial situs/arrangement (solitus, inversus, ambiguus), (2) AV connection (concordant, discordant, ambiguous, univentricular), (3) VA connection (concordant, discordant, double-outlet, single-outlet). Atrial situs is established first because morphologic right and left atria are identified by their appendage shape and the position of the IVC and abdominal viscera.

5On the parasternal long-axis view, which of the following structures is NORMALLY visualized?

A.Right ventricular outflow tract, pulmonary valve, and main pulmonary artery

B.Left atrium, mitral valve, left ventricle, aortic valve, and ascending aorta

C.Apical four-chamber view of all four chambers

D.Aortic arch and head/neck vessels

Explanation: Parasternal long-axis (PLAX) demonstrates the LA, mitral valve, LV, LV outflow tract, aortic valve, and proximal ascending aorta in a single plane. A small portion of the RV outflow tract appears anteriorly. PLAX is the foundational starting view for assessing LV size, septal continuity, and aortic root dimensions.

6ALARA in pediatric echocardiography most directly addresses which principle?

A.Maximizing image resolution at any cost

B.Keeping ultrasound exposure (output power, time) As Low As Reasonably Achievable for diagnostic quality

C.Always using the highest mechanical index

D.Standardizing exam length to 60 minutes regardless of indication

Explanation: ALARA (As Low As Reasonably Achievable) is the bioeffect-mitigation principle for ultrasound. Sonographers minimize acoustic output (mechanical index, thermal index) and dwell time while still acquiring diagnostic-quality images. This is especially important in fetal and neonatal imaging where tissues and developing structures may be more vulnerable to thermal/cavitation effects.

7A pediatric patient has a secundum atrial septal defect (ASD). What is the underlying embryologic origin of this defect?

A.Failure of the septum primum to fuse with endocardial cushions

B.Excessive resorption of septum primum or deficient septum secundum at the fossa ovalis

C.Persistence of a left-sided superior vena cava

D.Failure of the conotruncal septum to spiral

Explanation: Secundum ASD — the most common ASD type (~75%) — occurs at the fossa ovalis. It results from excessive resorption (fenestration) of the septum primum or insufficient growth of the septum secundum, leaving the fossa ovalis incompletely covered. Surgical or transcatheter device closure is typically successful.

8Which echocardiographic finding BEST distinguishes a primum ASD from a secundum ASD?

A.Location at the fossa ovalis with intact AV valve attachments

B.Defect in the inferior atrial septum with abnormal AV valve attachments at the same level (cleft mitral valve common)

C.Defect at the SVC-RA junction with anomalous right-upper pulmonary vein

D.Defect in the floor of the coronary sinus

Explanation: A primum ASD (ostium primum/partial AV canal) is located in the inferior portion of the atrial septum, where mitral and tricuspid valves attach at the SAME level (loss of the normal apical offset of the tricuspid valve). A cleft anterior mitral leaflet is commonly present, often producing mitral regurgitation.

9A complete (balanced) atrioventricular canal defect (also called complete AVSD) consists of which combination of lesions?

A.Primum ASD + inlet VSD + common AV valve

B.Secundum ASD + perimembranous VSD + cleft mitral valve only

C.Primum ASD + cleft mitral valve only (no VSD)

D.Sinus venosus ASD + muscular VSD

Explanation: A complete AV canal defect (CAVC, complete AVSD) has three components: (1) ostium primum ASD, (2) inlet VSD, and (3) a single common AV valve straddling the septum (Rastelli A/B/C classification by chordal attachments). Strongly associated with trisomy 21 (Down syndrome) — ~40% of children with Down syndrome have congenital heart disease, and AV canal is the most common.

10Which type of VSD is the MOST common, accounting for approximately 70-80% of all ventricular septal defects?

A.Muscular (trabecular) VSD

B.Perimembranous VSD

C.Inlet (canal-type) VSD

D.Doubly committed subarterial (supracristal) VSD

Explanation: Perimembranous VSDs are located in the membranous septum just below the aortic valve and adjacent to the tricuspid valve septal leaflet. They are the most common VSD type (70-80%). Aneurysmal tissue from the tricuspid septal leaflet can partially close them spontaneously over time.

RCCS Study Tips from Top Performers

1Use the segmental approach religiously: situs → AV connection → VA connection. Most complex CHD becomes manageable when broken down this way.

2Memorize syndromic-cardiac associations: Down = AV canal; 22q11 (DiGeorge) = TOF/truncus/IAA-B; Williams = supravalvar AS; Turner = bicuspid AV/coarctation; Noonan = pulmonary stenosis (often dysplastic) + HCM.

3Master single-ventricle staging order: Norwood/Sano (or BT shunt) → bidirectional Glenn → Fontan. Know expected saturations (Glenn ~80%, Fontan ~92-95%).

4Drill modified Bernoulli (4V²) and when the FULL Bernoulli is needed (proximal velocity >1 m/s, e.g., subaortic + AV stenosis).

5Practice Z-score interpretation: |Z|>2 abnormal; coronary Z>2.5 in Kawasaki; AHA 2017 thresholds (5-10, ≥10) for aneurysm classification.

6Recognize ALCAPA on every infant 'dilated cardiomyopathy' echo: bright papillary muscles, MR, dilated/dysfunctional LV, retrograde flow in LCA into PA on color Doppler.

7Practice ALARA: minimize MI/TI, narrow sector, raise focus, shorten dwell time — especially for fetal/neonatal scanning.

Frequently Asked Questions

What is the CCI RCCS exam?

RCCS (Registered Congenital Cardiac Sonographer) is CCI's specialty credential for sonographers focused on pediatric and congenital cardiac echocardiography. It is distinct from RCS (adult cardiac echo) and RCIS (cardiac catheterization).

How is RCCS different from ARDMS RDCS-Pediatric?

RCCS is from CCI; RDCS-PE is from ARDMS. Both certify pediatric/congenital cardiac sonography, and many sonographers hold one or both. Choice often depends on lab/employer preference and existing credentials in your state.

How many questions are on the RCCS exam?

The CCI RCCS exam contains approximately 170 multiple-choice questions delivered in 3 hours through Pearson VUE. Always verify current question count in the CCI Candidate Handbook before scheduling.

What is the passing score for RCCS?

CCI uses a scaled scoring system from 200 to 900 with a passing score of 700. Scaled scores account for question-difficulty variations between exam forms.

What congenital lesions should I prioritize for RCCS?

Master septal defects (ASD, VSD, AVSD), conotruncal defects (TOF, TGA, truncus, DORV), single-ventricle physiology and Norwood/Glenn/Fontan staging, and outflow obstructions. Know syndromic associations (Down/AV canal, 22q11/TOF/truncus/IAA-B, Williams/supravalvar AS, Turner/coarctation/BAV, Noonan/PS).

How long should I study for RCCS?

Plan 150-250 hours over 16-24 weeks. Prioritize segmental analysis, congenital lesion patterns by view, Doppler physics (modified Bernoulli, Qp:Qs), Z-scores, and Fontan-stage hemodynamics.

Is the RCCS exam offered remotely?

CCI exams are typically delivered at Pearson VUE test centers rather than via remote proctoring. Confirm current options on the CCI website before scheduling.
