Echocardiography-Guided Left Ventricular Lead Placement for Cardiac Resynchronization Therapy: Results of the Speckle Tracking Assisted Resynchronization Therapy for Electrode Region (STARTER) Trial Saba et al: Echo-Guided LV Lead Placement in CRT

[Mechanism of cardiac resynchronization therapy by real-time three-dimensional echocardiography in patients with heart failure].

We report the case of a 66-year-old man with heart failure NYHA class IV treated with biventricular pacing for cardiac resynchronization. The patient was evaluated by real-time three-dimensional transthoracic echocardiography before and 48 hours after pacemaker implantation. The use of three-dimensional echocardiography contributed to understanding the underlying mechanism involved in cardiac r...

Real-time three-dimensional echocardiography as a novel approach to assess left ventricular and Left Atrium reverse remodeling and to predict response to cardiac resynchronization therapy. Abstract

"Hyper-response" evaluated by 3D echocardiography after cardiac resynchronization therapy.

Cardiac resynchronization therapy consists of a promising treatment for patients with severe heart failure, but about 30% of patients do not exhibit clinical improvement with this procedure. However, approximately 10% of patients undergoing this therapy may have hyperresponsiveness, and three-dimensional echocardiography can provide an interesting option for the selection and evaluation of such...

Hype and hope in the use of echocardiography for selection for cardiac resynchronization therapy: the Tower of Babel revisited.

Initially, the rationale behind the use of echocardiography to assess mechanical synchrony seemed straightforward. Not all patients with left bundle-branch block (LBBB) have mechanical dyssynchrony, and this entity could be identified by measuring the contraction delay between different cardiac walls. It was hoped that better selection with echocardiography would minimize the nonresponder rate ...

[Three-dimensional imaging in cardiac resynchronization therapy].

Cardiac resynchronization therapy improves clinical symptoms and prognosis of heart failure patients. However, it has been shown that up to 40% of patients do not respond to this therapy. Three main determinants of cardiac resynchronization therapy response have been identified: left ventricular dyssynchrony, left ventricular lead position, and extent and location of myocardial scar tissue. Two...
