Mechanical dyssynchrony in patients with chronic heart failure: Classification, evaluation methods, significance in selection of patients for cardiac resynchronization therapy (CRT)
Appearance of cardiac resynchronization therapy (CRT) has considerably influenced the strategy of managing CHF patients. The major limitation of this intervention is the absence of response in 30% of patients, which may evidence an inadequate specificity of selection criteria. The review considers methods for evaluation of mechanical dyssynchrony, which may optimize selection of patients for CRT.
