Abstrakt: Background: Diffuse long coronary lesions require long overlapping stents which produce less than optimal long-term results. Sizing of long stents becomes difficult owing to tapering of coronaries and overlapping with excessive metal which makes restenosis a nagging problem on long-term follow-up. The optimal stent sizing becomes even more important when left main (LM) needs to be treated along with left ascending artery (LAD) or left circumflex artery (Lcx). The chronic total occlusions (CTO) represent other complex diffuse coronary lesions which not only require higher expertise and better hardware but also usually long lengths of overlapping stents. The long-tapered sirolimus-eluting stent system (BioMime Morph) has been successfully used in long diffuse lesions in individual coronaries including CTO but the use of the same in LM-LAD/LM-Lcx diffuse lesions has not been explored well where its tapered design can really be favourable. Case presentation: We here present a case of a 51-year-old hypertensive male presented with NSTEMI and angiography showing left main triple vessel disease with CTO of right coronary artery (RCA). We successfully stented the LM-LAD and RCA (staged) using a long-tapered BioMime Morph system. IVUS was used for optimising the LM-LAD stent. At 6 months follow-up, the patient was doing well on double anti-platelets. Conclusion: Complex coronary disease, involving the left main and LAD diffusely and CTO of RCA, can be well managed by using a single long-tapered stents thereby avoiding multiple stenting strategy. The stents with decremental diameter will provide better adaptation to the vessel size and their natural tapering. The usage of intravascular imaging helps in better optimisation of stents [ABSTRACT FROM AUTHOR]
