CCI RCS Echocardiography Review (142 Questions) – Coronary Anatomy, Hemodynamics, Valvular Disease & Cardiomyopathies | Cardiovascular Credentialing International (CCI) 2026 Exam

This comprehensive CCI Registered Cardiac Sonographer (RCS) review guide contains 142 high-yield echocardiography examination questions and fully explained answers specifically designed to prepare candidates for the 2026 Cardiovascular Credentialing International (CCI) credentialing examination. The material delivers an in-depth review of adult echocardiography principles, integrating cardiac anatomy, hemodynamics, congenital heart disease, Doppler physics, valvular pathology, prosthetic valves, cardiac masses, and cardiomyopathy assessment in a board-style question-and-answer format. The content is structured to strengthen clinical reasoning, reinforce interpretation skills, and improve examination performance through repetition of concepts frequently encountered on certification examinations. The guide begins with a detailed exploration of cardiac anatomy and echocardiographic imaging planes, emphasizing parasternal, apical, subcostal, and suprasternal views. Candidates review coronary artery anatomy, chamber relationships, valvular leaflet identification, coronary sinus localization, fetal circulation, embryologic development, intracardiac pressure relationships, and standard echocardiographic landmarks essential for accurate image acquisition and interpretation. The material also addresses fetal structures such as the ductus arteriosus, foramen ovale, endocardial cushions, and embryologic septation processes that commonly appear in congenital heart disease examinations. A substantial portion of the review focuses on coronary circulation and ischemic heart disease. Learners examine coronary artery distribution patterns, myocardial segment perfusion territories, complications of myocardial infarction, ventricular aneurysms, papillary muscle rupture, ventricular septal defects, Dressler syndrome, ventricular thrombus formation, and post-infarction hemodynamic consequences. Multiple clinical scenarios reinforce recognition of regional wall motion abnormalities and their relationship to specific coronary artery lesions. The document extensively reviews valvular heart disease and Doppler evaluation techniques. Topics include mitral stenosis and regurgitation, aortic stenosis and insufficiency, tricuspid and pulmonic pathology, pressure half-time calculations, dP/dt assessment, Qp/Qs determination, Bernoulli-derived pressure gradients, prosthetic valve assessment, prosthetic valve complications, and the distinguishing features of tissue and mechanical prostheses. The review further emphasizes the sonographer's role in identifying prosthetic dysfunction, pannus formation, endocarditis, dehiscence, thrombosis, and abnormal transvalvular hemodynamics. Candidates are also exposed to advanced concepts involving pulmonary hypertension, preload and afterload physiology, restrictive and dilated cardiomyopathies, hypertrophic obstructive cardiomyopathy (HOCM), infiltrative myocardial disease, systolic anterior motion (SAM), and characteristic M-mode, Doppler, and two-dimensional findings associated with each disorder. Additional sections address congenital heart defects, pericardial disease, cardiac tamponade, Beck's triad, intracardiac tumors, stress echocardiography principles, pharmacologic stress testing, and quality assurance standards relevant to contemporary echocardiography practice. The content reflects the domains outlined within the CCI Registered Cardiac Sonographer examination blueprint and serves as an intensive review resource for individuals seeking certification or clinical competency advancement. Its board-style presentation encourages active recall, promotes efficient revision, and provides practical reinforcement of concepts required in both academic and clinical echocardiography settings.
