Single-centre experience of STENTYS Xposition S in treatment of left main stem lesions

The second generation STENTYS Xposition S self-expanding stent with a novel balloon delivery system was launched in May 2015. The stents unique properties are well suited for the treatment of left main stem disease where large diameters, coverage of diameter differences and precise positioning are required. We report the first consecutive experience of using this device in the treatment of left main stem lesions.

20 consecutive patients with a mean age of 73.9±10.1 years were treated over a period of 8 months at our institution and were assessed on the parameters of technical, angiographic and procedural success.

Technical success was achieved in 95% of cases and angiographic success in 80% of cases. There was no incidence of geographical miss. Side branch access was straightforward, with no failure to recross stent struts, dilate or deploy a second stent if required. In this unselected clinical cohort, 2 critically ill patients with cardiogenic shock on presentation died despite successful revascularisation. There was no incidence of early stent related complications up to 30-day follow up.

This first consecutive series of left main lesions treated with STENTYS Xposition S documents high acute technical and procedural success rates.
