ABSTRACT

OBJECTIVES - To compare the effectiveness and safety of self-expandable, sirolimus-eluting Stentys stents (SES) and second-generation drug-eluting stents (DES-II) for the treatment of the unprotected left main (ULM).


BACKGROUND - SES may provide a valuable option to treat distal ULM, particularly when significant caliber gaps with side branches are observed.


METHODS - Patients from the multicenter SPARTA (clinicaltrials.gov -  NCT02784405) and FAILS2 registries were included. Propensity-score with matching was performed to account for the lack of randomization. Primary end-point was the rate of major adverse cardiovascular events (MACE, a composite of all cause death, myocardial infarction, target lesion revascularization [TLR], unstable angina and definite stent thrombosis [ST]). Single components of MACE were the secondary end-points.


RESULTS - Overall, 151 patients treated with SES and 1270 with DES-II were included; no differences in MACE rate at 250 days were observed (9.8% vs. 11.5%, P = 0.54). After propensity score with matching, 129 patients treated with SES and 258 with DES-II, of which about a third of female gender, were compared. After a follow-up of 250 days, MACE rate did not differ between the two groups (9.9% vs. 8.5%, P = 0.66), as well as the rate of ULM TLR (1.6% vs. 3.1%, P = 0.36) and definite ST (0.8% vs. 1.2%, P = 0.78). These results were consistent also when controlling for the treatment with provisional vs. 2-stents strategies for the ULM bifurcation.


CONCLUSION - SES use for ULM treatment was associated with a similar MACE rate compared to DES-II at an intermediate-term follow-up. SES might represent a potential option in this setting.
