Application of echocardiography in resynchronization treatment of heart failure patients

Chin Med J (Engl). 2012 Oct;125(19):3548-55.

Abstract

Objective: To review the updated research progress about the application of echocardiography in resynchronization treatment of chronic heart failure patients.

Data sources: The data used in this review were from PubMed, published in English and using the key terms "heart failure", "echocardiography" and "cardiac resynchronization therapy".

Study selection: Relevant articles were reviewed and selected to address the stated purpose.

Results: Increasing numbers of studies have suggested the importance of echocardiography in resynchronization treatment of chronic heart failure patients. Echocardiography can evaluate atrioventricular, inter- and intra-ventricular mechanical dyssynchrony before cardiac resynchronization therapy (CRT), as a guidance to assess the optimal left ventricular (LV) pacing location, optimize the atrioventricular and interventricular delays and predict response to CRT.

Conclusions: Echocardiography is both non invasive and easily repeatable, and plays a crucial role in appraisal of heart synchronism, instruction of actuator placement, optimization of the device procedure, and prediction of the response to CRT.
