We thank Dr. Kaneda for his interest in our study. We agree with the affirmation that the mean stented length for each study may not necessarily represent the stent length of the actual cases of stent thrombosis. Because of that, as we described in the Methods section (Statistical Analysis), we contacted the principal investigators of all studies in which at least one drug-eluting stent thrombosis was documented, requesting the total stent length for each of these cases (1). As we already reported in our study, the mean stented length for cases with drug-eluting stent thrombosis was 23.4 mm, which was significantly longer than that in those patients not suffering stent thrombosis (21.3 mm), thus confirming that the total stented length is related to the risk of thrombosis after drug-eluting stent implantation.
Moreover, our data are consistent with other studies that have also shown a significant relationship between stent length and the risk of stent thrombosis, both with bare-metal (2) and drug-eluting stents (3,4).
