A Mathematical Evaluation of Mitral Regurgitation Severity with EROA
It is to be investigated and verified that vena contracta width (VCW) obtained from color Doppler images and effective regurgitant orifice area (EROA) obtained from the VCW is capable of quantifying the severity of mitral regurgitation (MR). A mathematical expression has been developed between VCW and EROA. Vena contracta width is an efficient method for grading the severity of MR, but it is ve...
متن کاملPeak mitral inflow velocity predicts mitral regurgitation severity.
OBJECTIVES Mitral regurgitation (MR) is a common echocardiographic finding; however, there is no simple accurate method for quantification. The aim of this study was to develop an easily measured screening variable for hemodynamically significant MR. BACKGROUND The added regurgitant volume in MR increases the left atrial to left ventricular gradient, which then increases the peak mitral inflo...
متن کاملHemodynamics in ruptured chordae tendineae and chronic rheumatic mitral regurgitation.
Twenty-five patients with proven ruptured mitral chordae tendineae and 25 patients with chronic rheumatic mitral regurgitation were studied with quantitative biplane left-heart angiocardiography. Compared to the rheumatic patients, the ruptured chordae group had strikingly smaller left atrial maximum volume (mean: 119 + 47 vs 267 + 131 mI/M2 mean) and less compliant left atrium (mean: 1.61 1.52...
متن کاملEvaluation of the severity of mitral stenosis and regurgitation.
Indices have been developed that provide an improved means for evaluation of the degrees of severity of mitral stenosis and regurgitation. The severity of anatomic mitral valve disease found at surgery or autopsy was considered to be the determinant of the state of the valve. An index of the time for the diastolic atrioventricular pressure gradient to fall to half its value multiplied by 100 an...
متن کاملHemodynamics and annuloplasty in isolated mitral regurgitation in children.
Isolated mitral insufficiency in children is quantitated angiographically by comparing the stroke volumes of the right ventricle and left ventricle. The disease results in greater enlargement of the left atrium than of the left ventricle and is accompanied by a significant increase in left atrial "distensibility." Right and left heart pressures may be normal or may be increased; they tend to be...
