Abstract: Abstract：Left ventricular false tendon (LVFT) refers to the fibrous cord like structure of the left ventricle except the chordae tendineae that normally connects the papillary muscle to the mitral valve. LVFT is a congenital variation of the left ventricle, which developed from the inner myocardium of embryonic heart. LVFT consists of a variety of fibrous tissues, myocardial tissues, blood vessels originating from coronary branches, and Purkinje fibers originating from the left bundle branch conduction system. Echocardiographic examination often requires nonstandard sectional imaging, and its detection rate is much lower than that of autopsy. LVFT has been considered an anatomical variation without clinical significance for a long time, but with the progress of clinical studies, it is found that LVFT is not only related to harmless heart murmur, but also can inhibit left ventricular over-remodeling. In this review, we summarize the structure, function and clinical significance of LVFT.
