This review discusses the basic and evolving echocardiographic and cardiac magnetic resonance (CMR) approaches in the diagnosis and management of patients with hypertrophic cardiomyopathy (HCM).
Newer imaging technologies and techniques in both echocardiography and CMR have proved to add incremental value to our understanding of HCM. 3D reconstruction in echocardiography and CMR allows for more accurate morphological and volumetric assessment of the left ventricle. Echocardiographic and CMR-based left atrial assessment, including for its mechanical properties, has been shown to be correlated to outcomes and development of atrial fibrillation. Tissue characterization and scar burden quantification by late gadolinium enhancement on CMR has revolutionized our understanding of fibrotic processes in HCM and their contribution to disease severity and clinical outcomes. Cardiac imaging plays a crucial role in HCM patients. Using echocardiography and CMR as complementary modalities allows for improved diagnostics, optimization of treatment, and better prognostication.
本篇综述讨论了在诊断和管理肥厚型心肌病（HCM）患者时，超声心动图和心脏磁共振（CMR）的基本和不断发展的方法。
超声心动图和 CMR 中的新技术和技术已被证明为我们对 HCM 的理解增加了附加值。超声心动图和 CMR 中的 3D 重建可更准确地评估左心室的形态和容积。基于超声心动图和 CMR 的左心房评估，包括其机械特性，已被证明与结局和房颤的发生相关。CMR 上的晚期钆增强可对组织特征和瘢痕负荷进行量化，从而彻底改变了我们对 HCM 中纤维化过程及其对疾病严重程度和临床结局的影响的认识。心脏成像在 HCM 患者中起着至关重要的作用。使用超声心动图和 CMR 作为互补方式可改善诊断、优化治疗和更好地预测预后。
