Why the study?
Does the strain-derived dyssynchrony index correlate with improvement in left ventricular volume after CRT better than tissue velocity dyssynchrony indexes?
Does the strain-derived dyssynchrony index correlate with improvement in left ventricular volume after CRT better than tissue velocity dyssynchrony indexes?
Strain-derived dyssynchrony index is superior to tissue velocity dyssynchrony index for predicting left ventricular reverse remodeling after cardiac resynchronization therapy.
No takes yet. Share an insight, caveat, or question.
Strain-derived dyssynchrony index may better predict CRT response than velocity measures; leaves open its adoption for selection without prospective validation.
Miyazaki et al. (2008) studied this question.
