Outcomes from the new Synergy Megatron drug-eluting stent (DES) platform (Boston Scientific) are not yet reported. This study sought to evaluate periprocedural outcomes in patients undergoing percutaneous coronary intervention (PCI) using this technology.This was a retrospective study across two United Kingdom centers of 139 patients undergoing PCI of 146 coronary lesions using the Synergy Megatron DES. The primary endpoint was the rate of cardiovascular death. The secondary endpoint was the rate of a composite of non-fatal myocardial infarction, target-vessel revascularization, in-stent restenosis, and probable/definite stent thrombosis. Available intravascular ultrasound (IVUS) imaging was reviewed post hoc and evaluated according to predefined IVUS optimization criteria.Mean follow-up duration was 137.3 ± 38.3 days. The primary endpoint occurred in 0.7% of patients and the secondary endpoint occurred in 0.0% of patients. There were no cases of longitudinal stent deformation (LSD); in patients undergoing an IVUS-guided procedure, our criteria for successful IVUS optimization was achieved in 74.1% of left main stem (LMS) and 83.3% of right coronary artery (RCA) lesions. Mean minimal stent area (MSA) was 14.5 ± 3.4 mm² in the LMS, 10.0 ± 2.5 mm² in the left anterior descending coronary artery, 9.8 ± 3.0 mm² in the left circumflex, and 12.2 ± 4.0 mm² in the RCA.This study demonstrated very low rates of short-term major adverse cardiovascular events with no cases of LSD or acute/subacute stent thrombosis. It highlights the overexpansion capabilities of the Synergy Megatron DES platform. The technology safely and effectively facilitates IVUS-optimized stent parameters for the treatment of large proximal vessels and bifurcations. |
