 The long term safety and efficacy of the XIENCE V EECSS have been demonstrated in the SPIRIT FIRST trial up to 5 years, the SPIRIT II trial up to 4 years, and in the SPIRIT III Randomized Control Trial RCT up to 3 years. In addition, these pre-approval studies have shown low rates of Target Vessel Failure and Major Adverse Cardiac Events MACE that were observed to plateau or gradually decline after about 1 year and were consistently lower than the comparator arm of each study. This benefit in MACE is sustained for up to 5 years and is also independent of the first year results.
