Transcatheter aortic valve implantation (TAVI) has become a well-established intervention with reproducible and excellent early and mid-term outcomes. A minimalist approach to TAVI is already the standard of care in many experienced centers. In this report, we share our experience and opinions on how we can further simplify the TAVI procedure in hope to establish the best possible outcomes.

INTRODUCTION: Stent delivery failure may occur especially when treating complex coronary artery stenosis. XLIMUS (CARDIONOVUM GmbH, Bonn, Germany) is a new sirolimus-eluting stent (SES) with the following features: 1) cobalt chromium stent platform, with low (73 μm) strut thickness, (2) biodegradable polymer, and 3) potent antiproliferative drug (Sirolimus). Preliminary data suggest that XLIMUS SES may be ideal for the treatment of complex lesions. METHODS: In this registry, we assessed the deliverability, safety, and efficacy of percutaneous coronary interventions (PCI) using the XLIMUS SES in patients undergoing elective PCI in native coronary vessels for complex de novo lesions, including severe calcification, severe tortuosity, and chronic total occlusion...
