Is myocardial asynchronism a determinant of changes in functional mitral regurgitation severity during dynamic exercise in patients with chronic heart failure due to severe left ventricular systolic dysfunction?
Changes in MR are variable during dynamic exercise. LV asynchronism at rest substantially contributes to worsening of functional MR during dynamic exercise in patients with CHF due to LV systolic dysfunction.
The number of aspirated follicles during IVF treatment being higher than the collected number of oocyte leads to a statistically significant fall in the pregnancy rates. There is no correlation between the number of oocyte and pregnancy.
