Abstract

•
Subtle age-related ATTR-CM can complicate preexisting other HF etiologies.
•
Combined cardiomyopathies can present with atypical clinical/imaging presentation.
•
Multimodal imaging assessment is required in overlapping cardiomyopathies.
•
Absence of myocardial thickening should not rule out an infiltrative disorder.
•
Endomyocardial biopsy remains important in the context of equivocal imaging.

•微妙的年龄相关性atr - cm可使先前存在的其他HF病因复杂化。•合并心肌病可表现为不典型的临床/影像学表现。•重叠心肌病需要多模式成像评估。•心肌没有增厚不应排除浸润性疾病。•在影像不明确的情况下，心内膜活检仍然很重要。下载：下载高清图片（285KB）下载：下载全尺寸图片
