Dynamic geometry of the left atrium and left ventricle in acute mitral regurgitation.
The instantaneous transverse diameter of the left atrium, left ventricular free wall segment length (SEG), and the long axis of the anterior papillary muscle (APM) length were measured throughout the cardiac cycle, using ultrasonic dimension gauges together with left atrial and left ventricular pressures in 12 open-chest dogs. During atrial contraction, left atrial diameter decreased from 19.7 ...
متن کاملEvaluation of diastolic blood flow dynamic of the left ventricle in dogs with mitral valve regurgitation using vector flow mapping
Mitral valve regurgitation (MVR) is a common valvular disease in dogs. Hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (VFM), which shows the blood flow within the ventricles in vector and vortex flows. Blood flow within the left ventricle of MVR dogs was compared at different stages of MVR and to that of normal dogs. 14 normal dogs and...
متن کاملDynamic Geometry of the Left Ventricle in Mitral
High-speed biplane left ventricular (LV) cineangiograms were analyzed for changes in volume, shape, and dimensions in 35 patients. Ventriculographic studies in ten normal subjects characterized by an ejection fraction (E.F.) of 67±2% and an end-diastolic volume (EDV) of 90 + 8 ml/ m2 were compared with results from 25 patients with isolated mitral regurgitation of varying severity. Patients wit...
متن کاملThe transeptal approach to the left atrium in mitral regurgitation.
In the near future it should be possible to estimate the severity of mitral regurgitation and select patients for operation on purely clinical grounds. In the present state of knowledge haemodynamic data are obtained from right and left heart catheterization to give accuracy to the diagnosis of the individual case and quantitative meaning to the physical signs of the disease. Catheterization mu...
