Clinical Experience with Very High-Pressure Dilatation for Resistant Coronary Lesions
Highlights
- • Calcific coronary lesions can be so resistant to prevent symmetric stent expansion;
- • Stent underxpansion increase the risk of ISR an ST and VLST;
- • The OPN twin-layer technology provides an highly non-compliant structure that allows the use of very high pressure inflations
- • High-pressure dilatation (>40 ATM) was able to achieve adequate stent expansion
Abstract
Background
Calcific coronary lesions can be so resistant to prevent symmetric stent dilatation with high risk of ISR/thrombosis. The aim of the current study is to evaluate the safety and efficacy of super high-pressure dilatation (>30-to-45Atm) using a dedicated NC-balloon (OPN, SIS-Medical-AG, Winterthur-Switzerland).
