Minimally-invasive strategy for transcatheter implantation of second-generation Lotus™ aortic valve system

Transcatheter aortic valve implantation is a well-established therapy in patients with severe aortic stenosis. There has been a progressive improvement in device technology associated with increased experience of the interventionists, resulting in safer procedures with better outcomes. The first second-generation device approved in Brazil, Lotus™ Valve System (Boston Scientific Corporation, Natick, USA), incorporates several of these new characteristics. This report describes the first two cases, both successfully performed in the country, carried out under local anesthesia and conscious sedation.
