In eight patients in whom the Gorlin formula could be applied, there was excellent correlation (r = 0.95) between echocardiographic and hemodynamic measurements of mitral valve area. Each patient with tricuspid atresia had a very large mitral valve area (> 99th percentile of normal). It is ...
34-9, D). The pressure gradient and pressure half-time measurements are accurate in the setting of normal atrial and ventricular compliance (Table 34-4). In patients with severe aortic regurgitation, the pressure half-time is shortened, and this may result in an overestimate of mitral valve ...
All echocardiogarphic measurements of LV remodeling and mitral valve deformation are shown in table 2. All of the indices had an association with severity of FMR. Mitral annulus dimension in two views, as well as mitral annular area were higher in presence of greater degree of regurgitation. ...
These measurements were: Valve mobility It was assessed by measuring the anterior and posterior leaflets excursion [8]. To measure the excursion; in the parasternal long axis view, at maximum doming in early diastole, a line was drawn at the level of the mitral valve annulus (at the base ...
Eighty patients of isolated mitral stenosis were studied echo-cardiographically to assess the nature of the stenosed mitral valve as this seems to have a significant bearing on the surgical treatment of mitral stenosis. Echocardiographic findings were compared with the surgical observations and correlated...
When assessing MR by echocardiography, the key inquiries are severity, delineation of pathology in the components of the mitral valve apparatus, overall mechanism of MR, and, based on the probable mechanism, consideration of treatment strategies to reduce MR. As applied to CIMR, the echocardiograp...
