ABSTRACT
On the other hand, reassessment after CRT for 3 months showed a cumulative increase in LVEF by 7.7% and a decrease in LV volume by 22%. This was accompanied by a significant decrease in LV mass by 8% and a decrease in LV regional wall thickness. In fact, responders to LV reverse remodeling had a gain in LVEF of 11.8% and a reduction of LV mass by 15.5%.17 Therefore, LV reverse remodeling after CRT not only signifies
LV functional improvement, but also favorable structural alteration in response to the functional and hemodynamic improvement.
