Valves and Flow Positioning and Technique (Tech)-2D Flow/Velocity Measurements and Valves

Video Transcription

Video Summary

The talk explains how cardiac MRI (CMR) helps assess valvular disease when echocardiography is inconclusive or when results would change management. CMR can directly measure valve area, quantify stenosis and regurgitation, and evaluate ventricular size, function, and anatomy such as the aortic root or RVOT. It is especially useful for eccentric jets, poor echo windows, bicuspid aortic valves, pulmonary valve disease, and complex or multiple valve lesions. The speaker reviews imaging strategies for each valve: aortic stenosis and regurgitation, mitral regurgitation and stenosis, pulmonary stenosis and regurgitation, tricuspid regurgitation, and prosthetic valves. Key points include choosing the correct imaging plane, often using long-axis and perpendicular views, and placing flow measurements at the right location depending on whether the goal is valve area or velocity/regurgitant flow. CMR is highlighted as first-line for pulmonary valve assessment and highly valuable for right- and left-sided valve quantification.
