Predictive Factors, Efficacy, and Safety of Balloon Post-Dilation After Transcatheter Aortic Valve Implantation With a Balloon-Expandable Valve

JACC Cardiovascular Interventions, 06/08/2012

Balloon post–dilation (BPD) was needed in about one–fourth of the patients undergoing transcatheter aortic valve implantation (TAVI) with a balloon–expandable valve and was successful in about one–half of them. A higher degree of valve calcification and transfemoral approach predicted the need for BPD. BPD was not associated with any deleterious effect on valve function at mid–term follow–up, but a higher rate of cerebrovascular events was observed in patients who had BPD.
