This lesson focuses on the hemodynamic measurements made in the cardiac catheterization laboratory in the evaluation of mitral stenosis. Measurement of simultaneous left atrial and left ventricular pressures during diastole is the most accurate method to hemodynamically assess the mitral valve gradient. However, because access to the left atrium in the cath lab requires a transseptal puncture (from right atrium to left atrium), the pulmonary capillary wedge pressure is often used as a surrogate for left atrial pressure. The potential errors, pitfalls, and learning pearls in properly evaluating mitral stenosis are described.
