In Hypertrophic Cardiomyopathy Reduction of Relative Resting Myocardial Blood Flow Is Related to Late Enhancement, T2-Signal and LV Wall Thickness
OBJECTIVES To quantify resting myocardial blood flow (MBF) in the left ventricular (LV) wall of HCM patients and to determine the relationship to important parameters of disease: LV wall thickness, late gadolinium enhancement (LGE), T2-signal abnormalities (dark and bright signal), LV outflow tract obstruction and age. MATERIALS AND METHODS Seventy patients with proven HCM underwent cardiac M...
متن کاملRelationship of delayed enhancement by magnetic resonance to myocardial perfusion by positron emission tomography in hypertrophic cardiomyopathy.
BACKGROUND Presence of delayed enhancement (DE) on cardiac magnetic resonance (CMR) is associated with worse clinical outcomes in hypertrophic cardiomyopathy. We investigated the relationship between DE on CMR and myocardial ischemia in hypertrophic cardiomyopathy. METHODS AND RESULTS Hypertrophic cardiomyopathy patients (n=47) underwent CMR for assessment of DE and vasodilator stress ammonia...
متن کامل[Detection and quantification of myocardial fibrosis in hypertrophic cardiomyopathy by contrast-enhanced cardiovascular magnetic resonance].
INTRODUCTION AND OBJECTIVES Severity of hypertrophic cardiomyopathy has been associated with the amount of myocardial fibrosis in autopsy studies. Cardio-vascular magnetic resonance allows, by means of the delayed contrast-enhancement technique, an in vivo detection of focal myocardial fibrosis. Our aim was to study myocardial fibrosis in patients with hypertrophic cardiomyopathy by means of co...
متن کاملMyocardial fibrosis delineation in late gadolinium enhancement images of Hypertrophic Cardiomyopathy patients using deep learning methods
Introduction: Accurate delineation of myocardial fibrosis in Late Gadolinium Enhancement on Cardiac Magnetic Resonance (LGE-CMR) has a crucial role in the assessment and risk stratification of HCM patients. As this is time-consuming and requires expertise, automation can be essential in accelerating this process. This study aims to use Unet-based deep learning methods to automate the mentioned ...
متن کاملMyocardial structural, perfusion, and metabolic correlates of left bundle branch block mechanical derangement in patients with dilated cardiomyopathy: a tagged cardiac magnetic resonance and positron emission tomography study.
BACKGROUND Left bundle branch block (LBBB) influences on regional left ventricular (LV) structure, perfusion, and metabolism have not yet been thoroughly investigated in dilated cardiomyopathy patients. METHODS AND RESULTS Eleven dilated cardiomyopathy patients with LBBB (mean+/-SD age, 62+/-11 years; LV ejection fraction, 35+/-8%) and 7 dilated cardiomyopathy patients without LBBB (mean+/-SD...
