RDCS Pediatric study guide
RDCS Pediatric · Work through your exam, one topic at a time.
RDCS Pediatric Echocardiography refers to the Registered Diagnostic Cardiac Sonographer (RDCS) credential with a pediatric echocardiography specialty, one of the specialty examinations offered under the RDCS credential by the American Registry for Diagnostic Medical Sonography (ARDMS). ARDMS is an Inteleos member community, and its own materials state that ARDMS offers four credentials with 11 unique specialties; Pediatric Echocardiography is listed among the cardiovascular health examinations, alongside Adult Echocardiography and Fetal Echocardiography. The RDCS Pediatric study guide has 5 sections and about 1,670 words.
01Ultrasound Physics, Instrumentation, and Bioeffects/Safety
Axial resolution equals spatial pulse length divided by two, so it improves with higher frequency and fewer cycles per pulse. Lateral resolution depends on beam width at the focal zone.
357 words, about 2 min02Normal Pediatric Cardiac Anatomy, Physiology, and Embryology
Describe every heart in three steps. First, atrial situs: solitus, inversus, or ambiguous, decided by the morphologic right atrium with its broad appendage, crista terminalis, and IVC connection.
327 words, about 2 min03Congenital Heart Disease (Shunt, Obstructive, and Cyanotic Lesions)
ASD: secundum (mid-septal, often device-closable), primum (part of an AV septal defect), sinus venosus (high, frequently with partial anomalous pulmonary venous return - needs TEE or cross-sectional imaging), and coronary sinus defects. VSD: perimembranous (most common, risk of aortic cusp prolapse and regurgitation), muscular, inlet, and outlet/supracristal (subaortic and subpulmonary, tendency to aortic regurgitation).
323 words, about 2 min04Acquired Pediatric Cardiac Disease, Cardiomyopathy, and Ventricular Function Assessment
Kawasaki disease is the dominant acquired coronary disease of childhood: look for perivascular brightness, ectasia, and aneurysms, measured as z-scores; giant aneurysms (8 mm or more) carry the highest thrombosis risk. Myocarditis presents with global dysfunction, often with a small pericardial effusion.
322 words, about 2 min05Patient Care, Image Acquisition Protocols, and Post-Operative/Surgical Assessment
Children need warmth, a quiet environment, and a parent present; feed-and-swaddle works for infants, and sedation decisions follow institutional protocols with monitoring. Use age-appropriate ECG and blood pressure cuffs, and keep the examination efficient because tolerance is limited.
