Saw-tooth cardiomyopathy (STC), a rare form of left ventricular cardiomyopathy characterized by saw-tooth like myocardial projections extending from the lateral walls towards the ventricular cavity, is a newly discovered cardiomyopathy first described in 2009. Detailed cardiac magnetic resonance can demonstrate multiple dense myocardial protrusions originating from the inferior wall, interventricular septum and lateral ventricular walls, which differ from typical left ventricular noncompaction. STC case reports are increasing since the first discovery. A total of ten cases have been reported. This review focuses on the clinical presentation and imaging features of this disease and analyzes the latest evidence regarding STC. Furthermore, we summarize the clinical evidence from the current decade, which may enhance detection and diagnosis of this disease in the future.
锯齿状心肌病（STC）是一种罕见的左心室心肌病，其特征是心肌呈锯齿状从侧壁向心室腔延伸，是2009年首次描述的一种新发现的心肌病。详细的心脏磁共振成像可显示多个源于下壁、室间隔和侧心室壁的致密心肌突出物，这与典型的左心室心肌致密化不全不同。自首次发现以来，STC的病例报告不断增加。总共已报告了10例。本综述重点关注该疾病的临床表现和影像学特征，并分析有关STC的最新证据。此外，我们总结了近十年的临床证据，这可能会在未来提高对该疾病的检测和诊断水平。
