Electrocardiogram revealed sinus bradycardia with a ventricular rate of 54 beats per minute. Coronary angiography showed generally normal results, while echocardiography indicated a reduced left ventricular ejection fraction. Cardiac magnetic resonance imaging revealed mildly impaired left ventricular function (LVEF 47.4%), with focal mid-myocardial fibrosis in the basal anterior, septal, and inferior walls of the left ventricle, meeting the diagnostic criteria for non-dilated left ventricular cardiomyopathy. According to ESC guidelines, the patient is currently under follow-up observation.Conclusion: The imaging diagnosis of non-dilated left ventricular cardiomyopathy requires a comprehensive multimodal imaging approach. Cardiac magnetic resonance plays a crucial clinical role in the multimodal imaging evaluation of NDLVC.Keywords: nondilated left ventricular cardiomyopathy, cardiac magnetic resonance, echocardiography, dilated cardiomyopathy, left ventricular function
