Echocardiography constitutes the cornerstone for sudden cardiac death (SCD) risk stratification. Guidelines rely on the prognostic power of left ventricular ejection fraction (LVEF) to guide implantable cardioverter defibrillator (ICD) placement. However LVEF has important variability, and values obtained from different imaging modalities are not interchangeable. Furthermore novel echocardiographic techniques such as 3D echocardiography and strain imaging, are promising for improving patient selection. Mechanical dispersion (MD), a novel parameter derived from segmental srtain analysis that reflects myocardial contraction heterogeneity, has shown to be particularly promising. The aim of this chapter is to review current evidence for ICD patient selection for primary prevention and discuss the role of upcoming technology in echocardiography and its potential impact for arrhythmic risk stratification.

Abstract
Echocardiography constitutes the cornerstone for sudden cardiac death (SCD) risk stratification. Guidelines rely on the prognostic power of left ventricular ejection fraction (LVEF) to guide implantable cardioverter defibrillator (ICD) placement. However LVEF has important variability, and values obtained from different imaging modalities are not interchangeable. Furthermore novel echocardiographic techniques such as 3D echocardiography and strain imaging, are promising for improving patient selection. Mechanical dispersion (MD), a novel parameter derived from segmental srtain analysis that reflects myocardial contraction heterogeneity, has shown to be particularly promising. The aim of this chapter is to review current evidence for ICD patient selection for primary prevention and discuss the role of upcoming technology in echocardiography and its potential impact for arrhythmic risk stratification.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
