Observational StudyTranscatheter aortic valve implantation without balloon predilation: a single-center pilot experience.
To assess the results of transcatheter aortic valve implantation (TAVI) using the Medtronic CoreValve prosthesis (Medtronic, Minneapolis, MN), without balloon predilation, in high-risk patients with degenerated severe aortic stenosis. ⋯ These results suggest that direct CoreValve implantation in patients with severe aortic stenosis is feasible and may lead to hemodynamic and clinical improvement in patients who are poor candidates for aortic valve surgery, pending confirmation in larger series with longer follow-up.

Case ReportsAortic aneurysm 18 month after transfemoral implantation of a self-expandable aortic valve prosthesis.
We report a case of a new developed aortic aneurysm 18 month after transcatheter aortic valve implantation in an 80-year-old woman. The abnormality was an incidental finding during routine coronary angiography.

Case ReportsTranscatheter aortic valve implantation for treatment of failing homograft with preexisting mechanical mitral prosthesis.
Transcatheter aortic valve implantation is increasingly used to treat bioprosthetic degeneration. Valve-in-valve technique has been performed successfully to treat homograft, stentless, and stented bioprosthetic dysfunction. The presence of a prosthesis in the mitral position can make the transcatheter aortic valve implantation procedure challenging due to proximity of the mitral and aortic annuli. We describe the case of a 66-year-old who underwent the first successful implantation of Edwards Sapien device in a failing homograft in the presence of a mechanical mitral valve prosthesis.
