False tendon rupture mimicking chorda rupture.

False tendons are fibromuscular intracavitary bands that can mimic pathologic structures such as intraventricular chorda rupture, vegetation, or thrombus. False tendon rupture is a rare echocardiographic finding, reported in only a few case reports. In this case report, the authors present a patient with false tendon rupture that mimicked intraventricular chorda rupture.
