Additional acute improvement in left ventricular function after solving residual mechanical dyssynchrony in cardiac resynchronization patients

After cardiac resynchronization therapy (CRT), AV delay is usually set by “out of box” value while optimal VV interval is set using intracardiac electrocardiogram method (IEGM) according to the narrowest QRS width, regardless of the actual mechanical response of the left ventricle (LV). Our aim was to assess the presence of residual mechanical dyssynchrony after IEGM device optimization using echocardiographic parameters and to define echocardiographic and functional response in patients with early echo-guided optimization (“zero” OPT)
