922-58 Comparison of the Mitral Annulus in Normals and Patients with Cardiomyopathy by Dynamic Three-dimensional Reconstruction from Transesophageal Echocardiogramsdynamic three-dimensional reconstruction of MTEE images allows detailed quantitative analysis of MA shape and behavior in normals, HOCM and DCM....
The present study was designed to investigate the dimensions of mitral valve annulus in the presence of mitral regurgitation. Method. Fifty-four patients were examined. On transthoracic echocardiographic images, we performed linear measurements in the parasternal plane in order to define the size of ...
The longitudinal diameter of the LV was measured on the 4 chamber view as the distance between the mitral valve plane and the LV apex (a, c). On the 4 chamber view the transverse diameter was defined as the distance between the septum and the lateral wall at the basal level [18]. On...
d). The longitudinal diameter of the LV was measured on the 4 chamber view as the distance between the mitral valve plane and the LV apex (a,c). On the 4 chamber view the transverse diameter was defined as the
mitral annular velocity; E-wave = early mitral diastolic inflow velocity; FS = fractional shortening; IVRT = isovolumic relaxation time; IVSd = diastolic interventricular septal thickness; LAVI = left atrial volume index; LVEDD = left ventricular end-diastolic diameter; LVEF = left ventricular ...
For this purpose, the Doppler gate was placed over the basal segment of the left ventricular free wall just below the mitral annulus in the right parasternal short-axis view and also in the apical four-chamber view for some swine. For this four-chamber view, the probe was placed in ...
objective: to compare results of aortic valve replacement in patients with normal valve annulus and in those requiring annular enlargement. method: study includes 22 patients submitted to anterior and posterior annulus enlargement and 23 patients with a
Antero-posterior (AP) diameter, septo-lateral (SL) diameter, area and height were measured at 6 points of the cardiac cycle adapting commercially available software designed for assessing the mitral valve (MVQ, Phillips). The eccentricity ratio was calculated as AP/SL.ResultsTVA area decreases ...
In the absence of raised LAP the mitral annulus behaves normally, becoming more spherical at end-systole, a shape change that is attenuated by high LAP. This and the further increase in anteroposterior diameter, SI and MVA may partly contribute to the development of functional mitral regurgitation...
