Reduction of Para-Ring Regurgitation After Transcatheter Mitral Valve Replacement Into a Failed Mitral Annuloplasty Ring

Transcatheter valve-in-ring procedure has shown in a number of small case series to be feasible, safe, and able to offer short-term clinical and hemodynamic improvement in selected high-risk patients after failed surgical mitral annuloplasty ring repair [(1)][1].nnHereby, we report a case of a 70-

Multi-slice CT (MSCT) imaging in pretrans-catheter aortic valve implantation (TAVI) screening. How to perform and how to interpret

Aortic valve stenosis (AS) is the most common valvular heart disease among elderly. Trans-catheter aortic valve implantation (TAVI) has become an established and effective alternative therapeutical procedure for inoperable and high-risk patients with symptomatic AS. The procedural success is greatly dependent on a thorough pre-TAVI imaging screening. This requires a comprehensive and multi-modality approach, in which multi-slice computed tomography (MSCT) is the cornerstone in the selection of eligible patients, in choosing the appropriate prosthesis and size, and in mapping the safest access route for the intervention. From our experience of more than 400 TAVI procedures and many more MSCTs for screening purposes, we provide clinical and technical details on the use of MSCT pre-TAVI and brief review of the knowledge so far.
