This case report demonstrates the potential for contrast agent-free preprocedural planning (Figure 1A-C) and transcatheter aortic valve implantation (TAVI; Figure 1D-H) of a Direct Flow Medical® (DFM) transcatheter aortic valve (Direct Flow Medical, Santa Rosa, CA, USA), a device without a metallic frame, in an 84-year-old patient with renal failure and a severe aortic valve stenosis. Avoiding any application of contrast agent, and therefore its related complications, might extend even further the indication for TAVI implantation in such high-risk patients. This approach might currently be limited to certain anatomies and special clinical situations until larger studies confirm the strategy.##...
