A Case of Left Ventricular False Tendon with Ventricular Tachycardia.

A 48-year-old lady presented to the emergency department with a history of sudden onset palpitations associated with fatigue. 12-lead electrocardiogram was suggestive of ventricular tachycardia with right bundle branch block morphology [Figure 1], patient was hemodynamically unstable so electrically cardioverted. Subsequently two-dimensional transthoracic echocardiogram revealed dilated left ventricle with moderate LV dysfunction and showing false tendon attached from LV free wall to intraventricular septum [Figure 2], which could be the focus of ventricular tachycardia in our patient.

Left ventricular (LV) false tendons were first described in 1893 by the British anatomist and surgeon Sir William Turner.[1] LV false tendons are found in about half of hearts examined at autopsy and occur with equal frequency in normal hearts and in those with congenital malformations.[2]
