Key result
TSI-guided LV lead redirection increases stroke volume ~30% and improves symptoms in a nonresponder.
Why the study?
Does echocardiographic tissue synchronization imaging-guided surgical revision of left ventricular lead placement improve stroke volume and symptoms in a cardiac resynchronization therapy nonresponder?

Does echocardiographic tissue synchronization imaging-guided surgical revision of left ventricular lead placement improve stroke volume and symptoms in a cardiac resynchronization therapy nonresponder?
Echocardiographic tissue synchronization imaging can be useful to redirect left ventricular lead placement in cardiac resynchronization therapy nonresponders to improve hemodynamics and symptoms.

Hypothesis-generating for imaging-guided lead revision in CRT nonresponders; prospective trials needed before clinical adoption.
Dohi et al. (2005) conducted a case report in Severe symptomatic heart failure and left bundle branch block (n=1). Echocardiographic tissue synchronization imaging (TSI) to redirect left ventricular lead placement vs. Standard percutaneous approach (anterior coronary vein lead placement) was evaluated on Improvement in symptoms and ventricular function (stroke volume). Echocardiographic tissue synchronization imaging successfully redirected left ventricular lead placement in a clinical nonresponder, resulting in a 30% increase in stroke volume and symptomatic improvement.
