FEATURES
• Educational video library covering 2D and 3D TEE, interventional echocardiography, mechanical circulatory support, and clinical cases
• POCUS instruction for cardiac, lung, abdominal, vascular, and peripheral nerve block examinations
• Cardiac anatomy measurements and reference values for chamber size, ventricular function, diastology, and vascular structures
• Native valve assessment for aortic, mitral, tricuspid, and pulmonic stenosis and regurgitation
• Prosthetic valve reference for surgical valves, TAVR, and prosthesis evaluation
• Ultrasound and hemodynamic calculators for valve area, cardiac output, ventricular function, filling pressures, vascular resistance, shunts, fluid responsiveness, and more
• Cardiac equations, hemodynamic reference values, and ultrasound physics
• Clinical protocols, focused examination guidance, findings atlas, and reporting documentation
• Acquisition guidance, measurement tips, common pitfalls, and related clinical content
• Global search, favorites, related links, and personal notes
EchoRef connects ultrasound physics, image acquisition, echocardiographic interpretation, and bedside decision-making. Whether you are learning standard views, reviewing an unfamiliar finding, evaluating valve disease, or checking a calculation, the app makes relevant information easy to find.
