Heterogeneity of left ventricular wall thickening mechanisms.
BACKGROUND Myocardial fibers are grouped into lamina (or sheets) 3 to 4 cells thick. Fiber shortening produces systolic left ventricular (LV) wall thickening primarily by laminar extension, thickening, and shear, but the regional variability and transmural distribution of these 3 mechanisms are incompletely understood. METHODS AND RESULTS Nine sheep had transmural radiopaque markers inserted ...
متن کاملExercise in Dogs With Severe Left Ventricular Hypertrophy
The effects of exercise on regional myocardial blood flow and function were examined in the presence and absence of 13-adrenergic receptor blockade in 10 adult conscious dogs with severe left ventricular (LV) hypertrophy induced by aortic banding in puppies, which increased the LV weight/body weight ratio by 87%. Exercise at the most intense level studied increased LV systolic (+87±8 mm Hg) and...
متن کاملEffects of undersized mitral annuloplasty on regional transmural left ventricular wall strains and wall thickening mechanisms.
BACKGROUND Undersized mitral annuloplasty, widely used for ischemic and functional mitral regurgitation (MR), has been proposed as an "annular solution to a ventricular problem." Beyond relief of MR, it is thought to improve global left ventricular (LV) shape, hence potentially reducing myocardial stress and promoting beneficial reverse LV remodeling. We previously observed that undersized annu...
متن کاملMechanisms of subendocardial dysfunction in response to exercise in dogs with severe left ventricular hypertrophy.
The effects of exercise on regional myocardial blood flow and function were examined in the presence and absence of beta-adrenergic receptor blockade in 10 adult conscious dogs with severe left ventricular (LV) hypertrophy induced by aortic banding in puppies, which increased the LV weight/body weight ratio by 87%. Exercise at the most intense level studied increased LV systolic (+87 +/- 8 mm H...
متن کاملTransmural mechanics at a left ventricular epicardial pacing site
Running Title: Transmural mechanics at a LV epicardial pacing site ABSTRACT (250 words) Left ventricular (LV) epicardial pacing acutely reduces wall thickening at the pacing site. Because LV epicardial pacing also reduces transverse shear deformation, which is related to myocardial sheet shear, we hypothesized that impaired end-systolic wall thickening at the pacing site is due to reduction in ...
