The transcatheter aortic valve implantation (TAVI) consist an alternative treatment in patients with severe aortic stenosis. Multimodality imaging using transthoracic echocardiography (TTE) or transesophageal echocardiography (TOE) and multislice CT (MSCT) constitute cornerstone techniques for the pre-operative management, peri-procedural guidance, follow up and recognition of possible transcatheter valve related complications. CT angiography is much more accurate regarding the total definition of aortic annulus diameter and circumferential area.

Patients with significant comorbidity, or impaired left ventricular function are poor candidates for redo surgery at an acceptable risk at that later time point.
Methods And Results: This study reports the first-in-man transapical valve-in-ring implantations in the mitral position of the fully repositionable Lotus valve system approved for transcatheter aortic valve replacement in Europe.
Aims: In patients undergoing transcatheter aortic valve implantation (TAVI), the high prevalence of peripheral artery disease (PAD) limits femoral access and increases vascular complications that are associated with mortality and morbidity. Our study assessed the ability of a balloon-expandable large-bore vascular sheath to increase access-site availability and to reduce vascular complications.
Methods And Results: Among 257 patients from two centres, 43 patients underwent transfemoral TAVI with the use of the SoloPath balloon-expandable sheath due to complex iliofemoral access anatomy.
