Background: When coronary lesions involve segments > 48 mm, the only treatment possibility is stent overlapping which is associated with higher neointimal proliferation that lead to more restenosis. Furthermore, tapering of coronary arteries is a major challenge observed with long diffuse coronary lesions. This study attempted to assess the safety and performance of world's first commercialised long-tapered (60 mm) sirolimus-eluting coronary stent (SES) system for the treatment of long diffused de novo coronary lesions in real world scenario.

Methods: This was a retrospective, non-randomised, multicentre study which included 362 consecutive patients implanted with long-tapered BioMime™ Morph SES system for the treatment of long diffused de novo coronary lesions. Safety endpoint was major adverse cardiac events (MACE), which was defined as composite of cardiac death, myocardial infarction (MI) and ischemic-driven target lesion revascularization (ID-TLR), at 12-month follow-up.

Results: Out of 362 patients included, 170 (47.0%) were diabetic and 159 (43.9%) were hypertensive. The mean age of all patients was 61.09 ± 9.04 years. A total of 625 lesions were identified; out of which 402 lesions were intervened successfully using BioMime Morph. The cumulative incidence of MACE was 7 (2.0%) at 12-month follow-up which included four (1.1%) cardiac deaths, one (0.3%) case of MI and two (0.6%) ID-TLR. Acute stent thrombosis was reported in one (0.3%) patient.

Conclusions: The present study confirms the safety and performance of BioMime Morph, and hence, can be considered as a treatment of choice for long diffused tapered de novo coronary lesions in routine clinical practice.
