ARDMS Content Outline
The ARDMS Fetal Echocardiography (FE) specialty exam has approximately 145 multiple-choice questions over 3 hours with a passing score of 555 (scaled). The exam requires SPI certification as a prerequisite and carries a $350 fee. Content emphasizes normal fetal cardiac anatomy (four-chamber view, outflow tracts, three-vessel view), congenital heart disease detection (VSD, TGA, HLHS, TOF), arrhythmias, and measurement techniques (M-mode, Doppler, Tei index). First-time pass rates are approximately 75% for well-prepared candidates.
About the RDCS Fetal Echo Exam
The RDCS Fetal Echocardiography specialty exam assesses knowledge of fetal cardiac anatomy, physiology, and pathology using ultrasound techniques. The exam covers clinical care (7%), referral information review (7%), performance of fetal echo exams (46%), and evaluation of pathology/pathophysiology (40%). Candidates must first pass the SPI (Sonography Principles & Instrumentation) exam.

Frequently Asked Questions
What is the RDCS Fetal Echocardiography exam?
The RDCS (Registered Diagnostic Cardiac Sonographer) Fetal Echocardiography specialty exam is administered by ARDMS to certify sonographers in fetal cardiac imaging. The exam tests knowledge of fetal heart anatomy, normal development, congenital heart disease detection, and ultrasound techniques specific to prenatal cardiac assessment. Passing earns the RDCS credential with Fetal Echocardiography specialty designation.
What are the prerequisites for the RDCS Fetal Echo exam?
Candidates must first pass the SPI (Sonography Principles & Instrumentation) exam before taking the Fetal Echocardiography specialty exam. Additionally, you must meet one of ARDMS's eligibility pathways: (1) Completion of a cardiac sonography program, (2) Bachelor's degree with specific clinical experience, (3) Active RDCS Adult credential plus fetal echo clinical experience, or (4) Other ARDMS-approved pathways.
How many questions are on the RDCS Fetal Echo exam?
The ARDMS Fetal Echocardiography exam contains approximately 145 multiple-choice questions. Candidates have 3 hours to complete the exam. The questions cover clinical care (7%), referral information review (7%), performance of the fetal echo exam (46%), and pathology/pathophysiology evaluation (40%).
What is the passing score for RDCS Fetal Echocardiography?
The passing score is 555 on ARDMS's scaled scoring system (typically 300-700 scale). This equates to approximately 70% of questions answered correctly. ARDMS uses scaled scoring to ensure fairness across different exam forms. You will receive preliminary results at the test center, with official scores within 30 days.
What fetal echo views are most important for the exam?
The exam heavily emphasizes standard fetal cardiac views: Four-chamber view (assessment of septa, chambers, AV valves), Left ventricular outflow tract (aorta), Right ventricular outflow tract (pulmonary artery), Three-vessel view (PA, Ao, SVC relationship), Three-vessel trachea view, Short-axis views, and Ductal/aortic arch views. Know normal anatomy, landmarks, and sweep technique.
What congenital heart diseases are tested most frequently?
The exam focuses on common and critical congenital heart lesions: Ventricular Septal Defect (VSD), Tetralogy of Fallot (TOF), Transposition of the Great Arteries (TGA), Hypoplastic Left Heart Syndrome (HLHS), Coarctation of the Aorta, Atrioventricular Septal Defect (AVSD), Pulmonary Stenosis/Atresia, and Critical Aortic Stenosis. Know diagnostic criteria, associated findings, and postnatal implications.
How do I maintain my RDCS Fetal Echo credential?
RDCS credentials require recertification every 3 years. You must complete 36 continuing medical education (CME) credits during each 3-year cycle, with at least 12 credits in cardiac sonography. ARDMS accepts CME from various providers including SDMS, ASE, AIUM, and other approved organizations. You can also recertify by retaking the specialty exam.
