Application of echocardiography in resynchronization treatment of heart failure patients / 中华医学杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To review the updated research progress about the application of echocardiography in resynchronization treatment of chronic heart failure patients.</p><p><b>DATA SOURCES</b>The data used in this review were from PubMed, published in English and using the key terms "heart failure", "echocardiography" and "cardiac resynchronization therapy".</p><p><b>STUDY SELECTION</b>Relevant articles were reviewed and selected to address the stated purpose.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>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.</p>
