Intraventricular dyssynchrony assessment by real-time three-dimensional echocardiography.
Heart failure is exceedingly prevalent in the United States and in other developed countries. Treatment regimens are complex and now include electrical therapy. Methods for evaluating left ventricular dyssynchrony using echocardiography rather than QRS duration have been developed, with tissue Doppler velocity parameters being the most popular. Real-time three-dimensional echocardiography is another novel method for dyssynchrony evaluation that has potential advantages over existing techniques. The authors describe their experience with three-dimensional echocardiography dyssynchrony evaluation and offer insights into the direction that this technology must move to improve results.
