The Correlation between Left and Right Ventricular Ejection Fractions in Patients with Ischemic Heart Disease, Documented by Cardiac Magnetic Resonance Imaging
Introduction: The correlation between right and left ventricular ejection fractions (RVEF and LVEF, respectively) has been studied in only a small number of patients with a marked decrease in RVEF and LVEF. The aim of the present study was to compare LVEF and RVEF in patients with ischemic heart disease. RVEF and LVEF were measured by Cardiovascular Magnetic Resonance (CMR) imaging. Materials a...
متن کاملDiffuse myocardial fibrosis in hypertrophic cardiomyopathy can be identified by cardiovascular magnetic resonance, and is associated with left ventricular diastolic dysfunction
BACKGROUND The presence of myocardial fibrosis is associated with worse clinical outcomes in hypertrophic cardiomyopathy (HCM). Cardiovascular magnetic resonance (CMR) with late gadolinium enhancement (LGE) sequences can detect regional, but not diffuse myocardial fibrosis. Post-contrast T(1) mapping is an emerging CMR technique that may enable the non-invasive evaluation of diffuse myocardial ...
متن کاملMid-myocardial fibrosis by cardiac magnetic resonance in patients with lamin A/C cardiomyopathy: possible substrate for diastolic dysfunction.
AIMS We sought to identify patterns of myocardial fibrosis in vivo in patients with lamin cardiomyopathy, and to determine its functional significance. METHODS AND RESULTS Eleven patients sharing the identical mutation in LMNA without contraindication to magnetic resonance were identified from a 1016-member pedigree. Eight autopsy hearts from deceased relatives were reviewed. Patients and age...
متن کاملDiffuse myocardial fibrosis in patients after Fontan operation: a T1 relaxometry magnetic resonance pilot study
Background Patients with single ventricle (SV) circulations are at risk for heart failure, frequently burdened by both systolic and diastolic cardiac dysfunction. The mechanisms of adverse remodeling of functionally univentricular hearts are incompletely understood. Diffuse myocardial fibrosis is one of the candidate morphological substrates, for which cardiac magnetic resonance (CMR) derived n...
متن کاملDiffuse myocardial fibrosis and early strain abnormalities in asymptomatic type 2 diabetics without overt cardiovascular disease
Background Type 2 diabetes has been associated with a higher prevalence of diastolic dysfunction and congestive heart failure. A hypothesized contributor is the accelerated accumulation of diffuse myocardial fibrosis. In a cohort of type 2 diabetic patients without overt cardiovascular disease, we sought to explore the capacity of quantitative T1 mapping and feature-tracking based strain analys...
