Normal Value of Left Ventricular End-Systolic Elastance in Infants and Children
Background: In certain conditions, there is a need for a specific and improved measure of cardiac performance. Routine methods for assessing left ventricular (LV) function are based on image-analysis or right heart monitoring which do not allow evaluation of ventriculo-arterial interaction. Chen et al presented a noninvasive method allowing measurement of end-systolic pressure–volume relation ...
متن کاملAssessment of changes in left ventricular wall stress from the end-systolic pressure-area product.
We have measured the left ventricular (LV) end-systolic (ES) pressure-area product in 30 patients under general anaesthesia. We multiplied systolic arterial pressure with the ES cavity area obtained by transoesophageal echocardiography, and compared the product with M-mode derived ES wall stress before and during cardiovascular treatment. To attain appropriate mean arterial pressure during majo...
متن کاملEchocardiography-derived left ventricular end-systolic regional wall stress and matrix remodeling after experimental myocardial infarction.
OBJECTIVES We tested the hypothesis that regional end-systolic left ventricular (ESLV) wall stress is associated with extracellular matrix remodeling activity after myocardial infarction (MI). BACKGROUND Increased left ventricular (LV) wall stress is a stimulus for LV enlargement, and echocardiography can be used to estimate regional wall stress. A powerful validation of a noninvasive method ...
متن کاملContinuous measurements of left ventricular dimensions in intact, unanesthetized dogs.
Left ventricular dimensions have been directly measured for extended periods of time in intact unanesthetized dogs under various conditions. The diameter of the left ventricle during diastole is very large in relation to the change in diameter during each cycle. Thus, considerable quantities of blood remain within the chamber at the end of systolic ejection. The stroke output can be increased b...
متن کاملSimultaneous determination of left ventricular end-systolic pressure-volume and pressure-dimension relationships in closed-chest dogs.
The left ventricular end-systolic pressure-volume relationship is a load-insensitive measure of left ventricular performance. The relationship at end-systole between left ventricular pressure and dimension is more easily obtained, but the conflicting results of previous studies make it unclear if it has the same properties as the left ventricular end-systolic pressure-volume relationship. To ad...
