Can predilatation in transcatheter aortic valve implantation be omitted? - a prospective randomized study

Prior balloon valvuloplasty versus DIRECT transcatheter Aortic Valve Implantation (DIRECTAVI): study protocol for a randomized controlled trial

BACKGROUND Balloon predilatation of the aortic valve has been regarded as an essential step during the transcatheter aortic valve implantation (TAVI) procedure. However, recent evidence has suggested that aortic valvuloplasty may cause complications and that high success rates may be obtained without prior dilatation of the valve. We hypothesize that TAVI performed without predilatation of the ...

Fracturing the Ring of Small Mitroflow Bioprostheses by High-Pressure Balloon Predilatation in Transcatheter Aortic Valve-in-Valve Implantation.

Direct Transcatheter Heart Valve Implantation Versus Implantation With Balloon Predilatation: Insights From the Brazilian Transcatheter Aortic Valve Replacement Registry.

BACKGROUND Direct transcatheter aortic valve replacement (TAVR) is regarded as having potential advantages over TAVR with balloon aortic valve predilatation (BAVP) in reducing procedural complications, but there are few data to support this approach. METHODS AND RESULTS Patients included in the Brazilian TAVR registry with CoreValve and Sapien-XT prosthesis were compared according to the impl...

[Progress in transcatheter aortic valve implantation].

In 2002, the first patient underwent transcatheter aortic valve implantation for the treatment of severe symptomatic aortic stenosis. There followed several single-center trials which demonstrated that this new approach was feasible for the treatment of patients who were inoperable or at a very high risk with standard surgical aortic valve replacement. The results of recent multicenter trials u...

First dutch experience of the accurate neo self-expanding supra-annular valve for valve-in-valve transcatheter aortic valve implantation

We describe the first two cases of valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) using Accurate Neo device in the Netherlands. A 73-year-old man underwent transfemoral ViV-TAVI for severe stenosis in his 25-mm Carpentier-Edwards Perimount bioprosthesis. After balloon predilatation, a mediumsize Accurate Neo was advanced to the bioprosthetic annulus. First, its upper part w...
