A definitive method of assessing the severity of mitral stenosis is the simultaneous left heart catheterization and right heart catheterization. The right heart catheterization gives the physician the mean [[pulmonary capillary wedge pressure]], which is a reflection of the left atrial pressure. The left heart catheterization, on the other hand, gives the pressure in the [[left ventricle]]. By simultaneously taking these pressures, it is possible to determine the gradient between the left atrium and right atrium during ventricular [[diastole]], which is a marker for the severity of mitral stenosis. This method of evaluating mitral stenosis tends to over-estimate the degree of mitral stenosis, however, because of the time lag in the pressure tracings seen on the right heart catheterization and the slow Y descent seen on the wedge tracings. If a trans-septal puncture is made during right heart catheterization, however, the [[pressure gradient]] can accurately quantify the severity of mitral stenosis. | A definitive method of assessing the severity of mitral stenosis is the simultaneous left heart catheterization and right heart catheterization.

Overview
While echocardiography remains the diagnostic imaging modality of choice, simultaneous left and right heart catheterization demonstrates a pressure gradient such that the pulmonary capillary wedge pressure (a surrogate of the left atrial pressure) exceeds the left ventricular end diastolic pressure.
Cardiac Catheterization
A definitive method of assessing the severity of mitral stenosis is the simultaneous left heart catheterization and right heart catheterization. The right heart catheterization gives the physician the mean pulmonary capillary wedge pressure, which is a reflection of the left atrial pressure. The left heart catheterization, on the other hand, gives the pressure in the left ventricle. By simultaneously taking these pressures, it is possible to determine the gradient between the left atrium and right atrium during ventricular diastole, which is a marker for the severity of mitral stenosis. This method of evaluating mitral stenosis tends to over-estimate the degree of mitral stenosis, however, because of the time lag in the pressure tracings seen on the right heart catheterization and the slow Y descent seen on the wedge tracings. If a trans-septal puncture is made during right heart catheterization, however, the pressure gradient can accurately quantify the severity of mitral stenosis.

Invasive Hemodynamic Evaluation Indications (DO NOT EDIT)[1]
Class I |
"1. Cardiac catheterization for hemodynamic evaluation should be performed for assessment of severity of mitral stenosis when noninvasive tests are inconclusive or when there is discrepancy between noninvasive tests and clinical findings regarding severity of mitral stenosis.(Level of Evidence: C) " |
"2. Cardiac catheterization for hemodynamic evaluation including left ventriculography (to evaluate severity of mitral regurgitation) for patients with mitral stenosis is indicated when there is a discrepancy between the Doppler-derived mean gradient and valve area.(Level of Evidence: C) " |
Class III |
"1. Diagnostic cardiac catheterization is not recommended to assess the mitral valve hemodynamics when 2D and Doppler echocardiographic data are concordant with clinical findings.(Level of Evidence: C) " |
Class IIa |
"1. Cardiac catheterization is reasonable to assess the hemodynamic response of pulmonary artery and left atrial pressures to exercise when clinical symptoms and resting hemodynamics are discordant.(Level of Evidence: C) " |
"2. Cardiac catheterization is reasonable in patients with mitral stenosis to assess the cause of severe pulmonary arterial hypertension when out of proportion to severity of mitral stenosis as determined by noninvasive testing.(Level of Evidence: C) " |
