Abstract

UNLABELLED

Left ventricular (LV) thickening can be due to hypertrophy (concentric, asymmetric, eccentric) or remodelling (concentric or asymmetric). Pathological thickening may be caused by pressure overload, volume overload, infiltrative disorders, hypertrophic cardiomyopathy, athlete's heart or neoplastic infiltration. Magnetic resonance imaging (MRI) plays an important role in the comprehensive evaluation of LV thickening, including: establishing diagnosis, determining LV geometry, establishing aetiology, quantification, identifying prognostic factors, serial follow-up and treatment response. In this article, we review the aetiologies and pathophysiology of LV thickening, and demonstrate the comprehensive role of MRI in the evaluation of LV thickening.

TEACHING POINTS

• MRI plays an important role in the evaluation of LV thickening. • LV thickening can be due to either hypertrophy or remodelling. • Pathological thickening can be due to pressure/volume overload or infiltrative disorders.

摘要

未标注

左心室（LV）增厚可能是由于肥厚（同心性、非对称性、离心性）或重构（同心性或非对称性）。病理性增厚可能由压力负荷过重、容量负荷过重、浸润性疾病、肥厚型心肌病、运动员心脏或肿瘤浸润引起。磁共振成像（MRI）在左心室增厚的综合评估中发挥着重要作用，包括：确立诊断、确定左心室几何形态、明确病因、量化、识别预后因素、系列随访及治疗反应评估。在本文中，我们回顾了左心室增厚的病因及病理生理学，并阐述了MRI在左心室增厚评估中的综合作用。

教学要点

• MRI在左心室增厚评估中发挥重要作用。• 左心室增厚可能是由于肥厚或重构。• 病理性增厚可能由压力/容量负荷过重或浸润性疾病引起。
