The ultrathin-strut everolimus-eluting stent in a real-world population: the �Everythin� multicenter registry

ABSTRACT Introduction and objectives: Ultrathin-strut stents (UTS) represent a significant advancement in percutaneous coronary intervention. This study aimed to evaluate the safety and short- to mid-term outcomes of stenting with the thinnest struts on the market (50 μm) using a biodegradable everolimus-eluting polymer (Evermine 50) in real-world patients with coronary artery disease. Methods: A single-arm, multicenter, prospective study was conducted in real-world patients. A total of 161 patients with de novo lesions who received at least 1 UTS stent were enrolled. The primary safety endpoint was the occurrence of major adverse cardiovascular events, defined as cardiac death, target-vessel myocardial infarction, or the need for revascularization of the target lesion at 12 months. The incidence of stent thrombosis at 12 months was also analyzed. Results: The study included 161 patients with a mean age of 64 ± 14 years; 79% were male, 34% had diabetes, and 66% had hypertension. The most common indication for intervention was non-ST-segment elevation myocardial infarction (42%), followed by ST-segment elevation myocardial infarction (22%). The procedural success rate was 100%. At 12 months of follow-up, the incidence of MACE was 2.5%, and the definite stent thrombosis rate was 1.3%. Conclusions: The use of the 50 μm UTS stent with a biodegradable everolimus-eluting polymer demonstrated a favorable safety profile and good clinical outcomes in unselected patients at 1 year of follow-up.
