Why the study?
Do baseline Doppler parameters predict chronic left ventricular reduction in size by cardiac resynchronization therapy in patients with LV dysfunction and LBBB?
Do baseline Doppler parameters predict chronic left ventricular reduction in size by cardiac resynchronization therapy in patients with LV dysfunction and LBBB?
Baseline left ventricular pre-ejection interval and interventricular mechanical delay are useful echocardiographic predictors of favorable LV reverse remodeling following cardiac resynchronization therapy.
No takes yet. Share an insight, caveat, or question.
May aid echocardiographic CRT selection in LBBB; leaves open prospective validation of LVPEI-guided therapy.
Stockburger et al. (2007) studied this question.
