Left ventricular ejection performance and systolic muscle function in patients with mitral stenosis.
The status of systolic left ventricular (LV) performance in patients with isolated mitral stenosis (MS) is controversial. Potential alterations in LV architecture as well as loading conditions may have complex effects on LV ejection performance and muscle function. Therefore, we determined hemodynamic and angiographic LV ejection indexes (ejection fraction [EF], velocity of circumferential fibe...
متن کاملLeft ventricular function in rheumatic mitral stenosis.
Haemodynamic factors contributing to clinical disability in patients with rheumatic mitral stenosis have been under discussion and investigation for decades. Prior to the development of left heart catheterization, a low cardiac output in the presence of little or no pulmonary hypertension was taken as evidence for a myocardial 'insufficiency'. With the use of left heart catheterization, it was ...
متن کاملClinical Effect of Left Ventricular Dysfunction in Patients with Mitral Stenosis after Mitral Valve Replacement
BACKGROUND Mitral stenosis (MS) remains one of the important heart diseases. There are many factors that influence the clinical outcomes, and little is known about how left ventricular (LV) dysfunction clinically affects the prognosis of the patient with MS after mitral valve replacement (MVR). We reviewed our clinical experiences of MVR in patients with MS who had LV dysfunction. METHODS Bet...
متن کاملMitral stenosis with high left ventricular diastolic pressure.
Three patients with mitral stenosis are described, in whom the haemodynamic findings at cardiac catheterisation were more suggestive of left ventricular myocardial disease, in that the left ventricular diastolic pressure was high and the mitral valve gradient small. However, their echocardiograms showed abnormal wall movement during diastole characteristic of severe inflow obstruction, with slo...
متن کاملAssessment of left ventricular torsion in long axis view in patients with chronic stenosis of coronary arteries
Background: Left ventricular torsion is one of the most important biomechanical parameters of heart that routinely is measured in short axis view. A review of the literature has indicated that assessment of left ventricular torsion in short axis view has some limitations. In the present study, we evaluated whether torsion angle assessment in long axis view can be used as a diagnostic biomechan...
