Overview

Caution advised omitting predilatation in TAVI; case reports leave open optimal selection criteria.

Study Design

Type

Case Report (n=2)

Structured PICO

P
Population
Two cases undergoing transcatheter aortic valve implantation without initial balloon predilatation.
I
Intervention
Transcatheter aortic valve implantation (TAVI) without initial balloon predilatation
O
Outcome
Successful device crossing and implantation

While TAVI without balloon predilatation is often successful, these cases illustrate that predilatation may still be required to facilitate device crossing, highlighting the importance of careful case selection.

Limitations

  • Potential limitation in performing TAVI without balloon predilatation depending on case selection

Cite This Study

Chan et al. (2012) conducted a case report in Transcatheter aortic valve implantation (n=2). TAVI without balloon predilatation was evaluated. Attempted TAVI without initial balloon predilatation in two cases eventually required predilatation to facilitate device crossing and implantation, highlighting the importance of case selection.
