Left 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 کاملAnalysis of regional left ventricular wall motion during diastole in mitral stenosis.
Left ventricular angiograms of 16 patients with mitral stenosis and 18 normal subjects were digitised frame by frame to study regional diastolic wall motion. Left ventricular cavity volume and its rate of change were derived, and plots constructed to show regional wall motion throughout the cardiac cycle. Patients with mitral stenosis had a significantly reduced peak filling rate of 380±170 ml/...
متن کاملEchocardiographic evaluation of mitral stenosis using diastolic posterior left ventricular wall motion.
The slope of the posterior left ventricular wall motion in diastole (LVDS) was determined by echocardiography in 25 normal subjects and 21 patients with mitral stenosis. Patients with mitral stenosis had reduced LVDS that was related to the degree of mitral stenosis determined by calculated mitral valve area (r = 0.92). The mitral valve area correlated more closely with the LVDS than with the l...
متن کاملLeft 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 and right ventricular function during symptom-limited exercise in patients with isolated mitral stenosis.
Ventricular function during exercise in patients with mitral stenosis has not been widely studied. Accordingly, 20 patients with isolated mitral stenosis were assessed during supine, symptom-limited equilibrium radionuclide ventriculographic studies. All patients had a normal left ventricular (LV) ejection fraction at rest (greater than or equal to 50 percent), and all were in sinus rhythm. Lef...
