Key result
Attempted TAVI without initial balloon predilatation in two cases eventually required predilatation to facilitate device crossing and implantation, highlighting the importance of case selection.
Case Report (n=2)
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.

Caution advised omitting predilatation in TAVI; case reports leave open optimal selection criteria.
Balloon predilatation has been regarded as an essential step before implanting the self-expandable prosthesis during transcatheter aortic valve implantation (TAVI). Recent evidence showed that without balloon predilatation, an implantation success rate of >95% could be achieved. We report two cases in which balloon predilatation was not performed initially during TAVI but eventually required it to facilitate device crossing and implantation. They illustrated the importance of case selection and alerted us the potential limitation in performing TAVI without balloon predilatation.

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.
