Myocardial disarray. A critical review.

Asymmetric Septal Hypertrophy and Myocardial Fiber Disarray

The specificity and significance of the asymmetric septal hypertrophy (ASH) and myocardial fiber disarray of idiopathic hypertrophic subaortic stenosis (IHSS) is uncertain. To examine this we studied 215 hearts, including normal embryos, fetuses, children, and adults; and hearts with congenital and acquired disease. Disproportionate septal thickening was present in all embryos and in some abnor...

Myocardial fascicle and fiber disarray in 25 mu-thick sections.

We compared the histologic picture of myocardial fiber disarray in thin (4 mu) and thick (25 mu) sections of tissues obtained at autopsy from 18 adults and eight infants with clinically normal hearts, from 10 hearts with concentric hypertrophy (hypertensive patients), nine with myocardial infarction and four with hypertrophic cardiomyopathy (HCM). In the thick sections, so-called bizarre myocar...

Histopathological specificity of hypertrophic obstructive cardiomyopathy. Myocardial fibre disarray and myocardial fibrosis.

The topography and specificity of fibre disarray and fibrosis in hypertrophic obstructive cardiomyopathy were determined in a histological study comprising 40 necropsy hearts--10 with hypertrophic cardiomyopathy, 10 with congestive cardiomyopathy, 10 with aortic valve stenosis, and 10 normal hearts. Seven standard regional sections were sampled from each heart and graded "double-blind" (tissue ...

The current status of myocardial disarray in hypertrophic cardiomyopathy.

Rationing in health systems: A critical review

Background: It is difficult to provide health care services to all those in need of such services due to limited resources and unlimited demands. Thus, priority setting and rationing have to be applied. This study aimed at critically examining the concept of rationing in health sector and identifying its purposes, influencing factors, mechanisms, and outcomes.     Methods: The c...
