Welcome to our in-depth tutorial on the echocardiographic assessment of mitral stenosis. This video is crafted for cardiologists, sonographers, and medical students who aim to master the techniques and intricacies involved in diagnosing and evaluating mitral stenosis using echocardiography. We will cover key diagnostic methods including Doppler echocardiography, which is essential for measuring the pressure gradient across the mitral valve and assessing the severity of stenosis . Our discussion will also delve into the anatomy of the mitral valve, etiology, and how to use various echocardiographic techniques such as the pressure half-time, proximal isovelocity surface area, and continuity equation to provide a comprehensive evaluation.
