Highlights a rare mechanism of intraventricular dyssynchrony involving a false tendon and left bundle branch block in non-ischemic cardiomyopathy.
Suggests false tendon as possible mechanical driver of dyssynchrony in left bundle branch block; hypothesis-generating and needs larger studies.
Left ventricular (LV) false tendons are usually benign, intraventricular myocardial structures, which may cause functional malfunction or deformation of the LV cavity due to mechanical stretching and dilatation of the LV wall. We present a case of non-ischemic cardiomyopathy complicated with intraventricular dyssynchrony that was caused by complete left bundle branch block and the mechanical pressure exerted by the stiff false tendon on the weakened mid-septum during systole.
