<p><b><i>Objective:</i></b> Durable polymer sirolimus-eluting stents
(DP-SES) are associated with a low risk of stent thrombosis;
biodegradable polymer drug-eluting stents (BP-DES) were designed to
reduce these risks. However, their benefits are still variable. <b><i>Method:</i></b>
We undertook a meta-analysis of randomized trials identified by
systematic searches of Medline, Embase, and the Cochrane Database. <b><i>Results:</i></b>
Eleven studies (9,676 patients) with a mean follow-up of 22.6 months
were included. Overall, compared with DP-SES, BP-DES significantly
lowered the rate of definite or probable stent thrombosis (RR, 0.73; 95%
CI, 0.55-0.97; p = 0.03; I<sup>2</sup> = 0.0%) due to a decreased risk of very late stent thrombosis (RR, 0.26; 95% CI, 0.11-0.63; p = 0.00; I<sup>2</sup>
= 0.0%). However, BP-DES were associated with a comparable rate of
early and late stent thrombosis. Meanwhile, BP-DES were associated with a
broadly equivalent risk of target vessel revascularization (RR, 0.90;
95% CI, 0.78-1.03; p = 0.13; I<sup>2</sup> = 0.0%), cardiac death (RR, 0.89; 95% CI, 0.72-1.09; p = 0.24; I<sup>2</sup> = 0.0%), myocardial infarction (RR, 1.03; 95% CI, 0.84-1.26; p = 0.79; I<sup>2</sup> = 0.0%), and major adverse cardiac events (MACE; RR, 0.91; 95% CI, 0.83-1.0; p = 0.08; I<sup>2</sup>
= 0.0%). Furthermore, angiographic data showed that in-stent and
in-segment late luminal loss were similar between the two groups. <b><i>Conclusions:</i></b>
Compared with DP-SES, BP-DES were associated with a lower rate of very
late stent thrombosis and an equivalent risk of MACE. Larger randomized
studies are needed to confirm this finding.</p>
