OBJECTIVE
To describe the initial experience of cardiac contractility modulation (CCM) implantation in Latin America.
METHOD
We present the first two cases in Latin America of patients with heart failure with reduced left ventricular ejection fraction (LVEF) not candidates for cardiac resynchronization therapy in whom a CCM device was implanted. Results.
RESULTS
In both patients we described improvement of the 6-minute walk test, functional class according to the NYHA and LVEF.
CONCLUSIONS
The modulation of cardiac contractility is currently a treatment option for patients with heart failure in functional class III-IV, with LVEF 25-45%, and a QRS < 130 ms who are not candidates for cardiac resynchronization therapy.
目的
描述心脏收缩力调制（CCM）植入术在拉丁美洲的初步经验。
方法
我们介绍拉丁美洲首例两例左心室射血分数（LVEF）降低的心力衰竭患者，他们不适合接受心脏再同步治疗，但植入了CCM装置。结果。
结果
在这两名患者中，我们观察到6分钟步行试验、根据纽约心脏协会（NYHA）分级的功能分级以及LVEF均有改善。
结论
对于功能分级为III-IV级、LVEF为25%-45%且QRS<130毫秒、不适合接受心脏再同步治疗的心力衰竭患者，心脏收缩力调制目前是一种治疗选择。
