| Research Abstract |
An echocardiographic index named i-Index for predicting responses to cardiac resynchronization therapy (CRT) is a newly-devised one in the post- PROSPECT study era. Receiver-operating characteristics curve analyses wereused to examine the overall discriminatory power of i-Index, and Ts lateral-septum to predict LV volume and clinical responses. LVESV decreased .15% in 58% of 106 patients at 6-month follow up. The area under the curves of i-Index for LV volumeresponses to CRT was 0.86, and these was greater than those of Ts lateral-septum for the CRT response outcomes of 0.75. And more responders were included in the opposite sided lead positioning group. We conclude that i-Index can be a complementary measure for better CRT patient selection and RV and LV leads should be implanted at opposite site around the LV for good prognosis after CRT.
