Left ventricular false tendon and aortic coarctation


Left ventricular false tendons are fibromuscular structures that arise from the inner trabeculated myocardial layer of the left ventricle. They can be found, most of the times in autopsy or incidental findings, as single or multiple structures that traverse the left ventricle.

False tendons, as in this patient, may lead to arrhythmias and also causing left ventricular hypertrophy with resultant systolic dysfunction. In some cases, they can be found in addition of others cardiac abnormalities as shown in this case.
