Why the study?
Does combined catheterization of the left and right sides of the heart allow for accurate evaluation of pressure-flow relations and estimation of orifice size in patients with mitral stenosis?
Does combined catheterization of the left and right sides of the heart allow for accurate evaluation of pressure-flow relations and estimation of orifice size in patients with mitral stenosis?
Combined right and left heart catheterization provides a method for evaluating pressure-flow relations and estimating orifice size in patients with mitral stenosis.
May support hemodynamic assessment of mitral stenosis; leaves open validation before routine adoption.
SIMULTANEOUS catheterization of the left and right sides of the heart for evaluation of mitral and aortic stenosis has recently been reported.1 2 3 4 The effects of mitral stenosis upon the pulmonary circulation and cardiac output have been extensively investigated by right-sided catheterization.5 6 7 With the introduction of left-sided catheterization a method of accurate measurement of pressure gradient across a stenotic orifice became available.8 9 10 With the subsequent application of combined heart catheterization a more accurate evaluation of pressure-flow relations, as well as estimation of orifice size, can be obtained.Methods and MaterialsOne hundred and twenty patients with mitral stenosis were studied by . . .
