  • Title: Transcatheter aortic valve implantation without balloon predilatation: not always feasible.
    Author: Chan PH, Mario CD, Moat N.
    Journal: Catheter Cardiovasc Interv; 2013 Aug 01; 82(2):328-32. PubMed ID: 22517798.
    Abstract:
    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.
