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...
b) and systole (c,d) on the 4 chamber view (a,c) and short axis view (b,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 ...
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 ...
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 ...
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
We also found a positive relationship between age, body weight, and the ratio of the left ventricular internal diameter to its wall thickness, as well as the relative left atrial size. Conclusion Many electro- and echocardiographic measures of cardiac morphology and function of healthy swine are ...
valvePediatricBackground The mitral valve has a complex three-dimensional (3D) morphology that is incompletely described by two-dimensional echocardiography (echo). Three-dimensional echo provides a more robust tool to analyze the mitral valve. The shape of the mitral annulus and leaflets, and ...
The annulus of the valve of the pulmonary artery increased proportionally in relation to the inferior circumference of the infundibulum. The increase in the latter was 36 per cent greater than the increase in the valvular orifice of the pulmonary artery....
