组织同步显像技术追踪评价心脏再同步化治疗
Evaluation of Cardiac Resynchronization Therapy by Tissue Synchronization Image
目的 应用超声心动图新技术组织同步显像(TSI)追踪评价心力衰竭患者心脏再同步化治疗（CRT）术后疗效。方法 接受CRT的慢性心力衰竭患者28例，用常规超声心动图及组织同步显像技术观察术前术后左室射血分数（LVEF）、二尖瓣反流面积(MR-A)和主动脉-流速时间积分（AV-VTI）；观测心脏收缩同步性指标：左室12节段达峰时间标准差（12－Tp-SD）、左室12节段达峰时间最大差（12-Tp-MAX-D）、左室6基底节段达峰时间标准差（6B-Tp-SD）和左右室间机械延迟（IVMD）的变化。结果 CRT术后短期和中长期，左室收缩功能参数LVEF和AV-VTI均较术前提高，MR-A减少，室间不同步及左室内不同步情况均有改善。结论 超声心动图以及组织同步显像新技术对CRT术前病例选择、预测疗效、指导双室起搏器植入、术后疗效评价具有重要意义。
Objective To evaluate the effect of cardiac resynchronization therapy (CRT) by tissue synchronization imaging（TSI）echocardiography in patients with severe heart failure. Methods 28 patients with HF undergoing CRT were studied. Evaluated the LVEF, AV-VTI, MR-A, 12-Tp-SD, 12-Tp-MAX-D, 6B-Tp-SD and IVMD, during pre or post CRT by conventional echocardiography and TSI. Results Left ventricle systolic function parameters (LVEF and AV-VTI) increased greatly after CRT in short and mid-long term follow-up. Meanwhile MR-A reduced, the parameters of interventricular synchronism and LV intraventricular synchronism decreased as well compared with pre-operation. Conclusion TSI has significant meaning for selection suitable patients, predicting responser and guiding biventricular pacing (BVP) implantation, appreciation effect of CRT.
