Transcatheter aortic valve implantation (TAVI) is nowadays an accepted method of treatment for patients with symptomatic severe aortic stenosis who are inoperable or at very high risk of classic surgical aortic valve replacement. The Lotus valve system is a new generation TAVI device composed of a self-expanding stent prosthesis with implemented bovine pericardial leaflets, which is designed to facilitate repositioning, resheathing, and retrieval, even in the fully expanded and functioning position before the final release. In addition, the Lotus valve is surrounded by a flexible membrane to seal paravalvular gaps between the prosthesis and native valve. We present the first Polish experiences with the Lotus valve system. Due to its unique features, the Lotus valve may improve the prognosis in patients with inoperable or high risk critical aortic stenosis.
