Abstract
BACKGROUND

The EverProTM (Sahajanand Laser Technology Ltd., India) everolimus-eluting coronary stent system (EES) is a second-generation drug-eluting stent with a biodegradable polymer.

AIM

To determine the safety and performance of the EverProTM EES in patients with coronary artery disease (CAD) during a 1-year clinical follow-up.

METHODS

This observational, retrospective, single-center study enrolled patients who had been implanted with the EverProTM stent between June 1, 2018 and January 31, 2019, and had completed a 1-year follow-up period after the index procedure. The primary clinical endpoint was major adverse cardiac events (MACE) at 6 mo defined as the composite of cardiac death, myocardial infarction (MI), and target lesion revascularization (TLR). Secondary endpoints were the incidence of TLR at 1, 6 and 12 mo follow-up, MACE at 1 and 12 mo follow-up, and stent thrombosis up to 1 year after the index procedure.

RESULTS

The study population comprised 77 patients (98 lesions). A total of 37 (48.1%) patients had comorbid hypertension. In total, 26 (33.8%) patients presented with ST segment elevation MI and 10.4% patients with non-ST segment elevation MI. Treated lesions were located mainly in the left anterior descending artery (49%) followed by the right coronary artery (29.6%), left circumflex (12.2%) and obtuse marginal (9.2%) arteries. The majority of patients were with single-vessel disease (79%), 22.2% of lesions had a mild to severe thrombus load, and 94.9% were American College of Cardiology/American Heart Association type B or C. De novo stenting was performed in 96.9% of patients and 3% were treated for in-stent restenosis. Procedural success was attained in all patients. In-hospital or follow-up MACE and stent thrombosis were not reported during the 1-year follow-up period.

CONCLUSION

These findings suggest that the EverProTM EES is a safe and effective treatment option with no MACE or stent thrombosis reported during the 1-year study period in patients with CAD.

Core Tip: New-generation drug-eluting stents (DES) reduce the risk of stent thrombosis. However, the everolimus-eluting coronary stent system (EES) exerts higher interaction with rapamycin complex 2, higher bioavailability, shorter half-life than sirolimus, decreases vascular inflammation and promotes rapid endothelialization; therefore, outperforms paclitaxel DES in safety and efficacy. EverProTM, a second-generation EES with a biodegradable polymer and a 60 μm cobalt-chromium platform design, facilitates reduction in intra-arterial injury. This observational study enrolled 77 patients with coronary artery disease (CAD), implanted with the EverProTM stent who completed a 1-year follow-up period after the index procedure. Our findings suggested that EverProTM EES is safe and effective with no major adverse cardiac events/stent thrombosis during the 1 year follow-up period in patients with CAD.
