Optical coherence tomography assessment of a new dedicated bifurcation stent

Abstract

Aims: Dedicated bifurcation stents should facilitate deployment and improve coverage of bifurcational lesions. We used optical coherence tomography (OCT) to assess bifurcation lesions treated with a dedicated stent implanted in the side branch (SB) in conjunction with drug eluting stents in the main vessel (MV) in a culotte-like fashion. Methods and results: Nine patients treated with the Tryton stent underwent postprocedural OCT examination. Total percent of malapposed struts per patient was 18.1±8.7%. The longitudinal distribution of the percent of malapposed struts per patient showed that the prevalence of malapposed struts was significantly higher at the level of the bifurcation (33.3%),..
