Extensive myocardial fibrosis in a patient with hypertrophic cardiomyopathy and ventricular tachycardia without traditional high-risk features.
نویسندگان
چکیده
Although patients with hypertrophic cardiomyopathy (HCM) and without conventional risk factors for sudden death are generally considered at low risk, the magnitude of risk in such patients remains unknown, and additional markers of prognosis may permit more accurate risk stratification.1–3 We report a patient with HCM and without conventional risk factors who had a sustained life-threatening ventricular tachyarrhythmia 6 months after identification of extensive myocardial fibrosis at contrast-enhanced cardiovascular magnetic resonance (CMR).

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 ...

AIM To measure the prevalence of abnormal rest perfusion in a population of consecutive patients with known hypertrophic cardiomyopathy (HCM) referred for cardiovascular MRI (CMR), and to assess any associations between abnormal rest perfusion and the presence, pattern, and severity of myocardial scar and the presence of risk factors for sudden death. MATERIALS AND METHODS Eighty consecutive ...

INTRODUCTION AND OBJECTIVES In patients with hypertrophic cardiomyopathy, myocardial fibrosis can be detected by late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging. We investigated the relationships between the extent of LGE, left ventricular morphology and function, and clinical characteristics. METHODS Both cine and gadolinium-enhanced magnetic resonance imaging were pe...

OBJECTIVE Myocardial fibrosis identified by late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) in patients with hypertrophic cardiomyopathy (HCM) is associated with adverse cardiovascular events, but its value as an independent risk factor for sudden cardiac death (SCD) is unknown. We investigated the role of LGE-CMR in the risk stratification of HCM. METHODS We conduct...
