چکیده
Methods Consecutive pediatric subjects with HCM (n=12) or DCM (n=8) undergoing routine clinical CMR were recruited. Native and post contrast T1 mapping was performed using Modified Look-Locker inversion recovery (MOLLI) sequences in all subjects. In 10 subjects, the maximum and mean circumferential strains were also examined using Displacement Encoding With Stimulated Echoes (DENSE). Data for both T1 mapping and strain were evaluated in a 16 segment cardiac model.

DIFFUSE CORONARY ARTERIAL ECTASIA WITH HYPERTROPHIC CARDIOMYOPATHY
A 40 year old male, a known case of hypertrophic cardiomyopathy, was admitted for catheterization. At catheterization and angiography, septum was hypertrophied to about 5cm and diffuse coronary artery aneurysm was revealed. We found no previous report of coronary artery aneurysm in hypertrophic cardiomyopathy.
متن کاملDiffuse myocardial fibrosis in pediatric hypertrophic cardiomyopathy
Background Fibrosis is a common end-point in pathological processes. It is unclear, however, if diffuse fibrosis occurs early in the pathogenesis of hypertrophic cardiomyopathy (HCM). The purpose of this study was to evaluate the presence of diffuse myocardial fibrosis in children and adolescents with HCM using quantification of T1 changes late after gadolinium administration and to assess for ...
متن کاملComparison between Brain Natriuretic Peptide and Calcitonin Gene Related Peptide in Children with Dilated Cardiomyopathy
Background: Dilated cardiomyopathy (DCM) is revealed with the left ventricular dilatation and systolic dysfunction. This study was performed to determine the level of Calcitonin Gene Related Peptide (CGRP) and Brain Natriuretic Peptide (BNP) in children with dilated cardiomyopathy and controls and comparison of these two biomarkers in patients. Materials and Methods: This case-control study was...
متن کاملT1 mapping in discrimination between hypertrophic and hypertensive cardiomyopathy
Background The differential diagnosis of hypertrophic phenotype remains challenging in clinical practice, in particular between hypertrophy cardiomyopathy (HCM) and increased left ventricular wall thickness (LVWT) due to systemic hypertension. Diffuse myocardial fibrosis is the characteristic feature in HCM, whereas hypertensive response is underpinned by addition of myofibrils in otherwise nor...
متن کاملHeterogeneity of intramural function in hypertrophic cardiomyopathy: mechanistic insights from MRI late gadolinium enhancement and high-resolution displacement encoding with stimulated echoes strain maps.
BACKGROUND In hypertrophic cardiomyopathy (HCM), myocardial abnormalities are commonly heterogeneous. Two patterns of late gadolinium enhancement (LGE) have been reported: a bright "confluent" and an intermediate intensity abnormality termed "diffuse," each representing different degrees of myocardial scarring. We used MRI to study the relation between intramural cardiac function and the extent...
