The authors discuss an incremental value of assessing left ventricular (LV) twist mechanics in patients with heart failure (HF) and its potential usefulness in characterizing response to cardiac resynchronization therapy (CRT) and reversal of LV remodeling at 6 months follow-up. They also underscore a critical relationship between LV lead position and changes in LV twist after CRT, and suggest that the reversal of LV remodeling in HF patients following CRT primarily results from restoration of the global sequence of LV twist mechanics.
作者讨论了评估心力衰竭（HF）患者左心室（LV）扭转力学的增量价值，及其在表征心脏再同步治疗（CRT）反应和 6 个月随访时 LV 重构逆转中的潜在用途。他们还强调了 LV 导联位置与 CRT 后 LV 扭转变化之间的关键关系，并表明 CRT 后 HF 患者 LV 重构的逆转主要归因于 LV 扭转力学整体顺序的恢复。
