- Abstract
<bold>Objectives: </bold>To assess the necessity for balloon aortic valvuloplasty (BAV) during transfemoral transcatheter aortic valve implantation (TAVI) when using balloon-expandable valves.<bold>Background: </bold>BAV is a usual part of TAVI procedures, prior to valve implantation. However, the benefits and necessity of this are unknown and recent evidence in self-expanding valves suggests it may not be necessary.<bold>Methods: </bold>Retrospective single-center study of 154 patients undergoing first-time, transfemoral TAVI for native aortic valve stenosis, with (N = 76), and without (N = 78), BAV as part of the procedure. Data collected included demographic, procedural, and outcome data.<bold>Results: </bold>BAV did not alter VARC-2 defined procedural success or early safety compared to not performing a BAV, including mortality, degree of aortic regurgitation, or need for post-TAVI balloon dilatation, although there was a strong trend to reduced stroke when not performing a BAV. There was a significantly reduced procedural time (P = 0.01) and fluoroscopic time (P < 0.001) without performing a BAV. There were no differences in cerebral embolization (solid, gaseous, or total emboli) noted between the 2 groups, as measured on transcranial doppler (TCD).<bold>Conclusions: </bold>TAVI can be effectively and safely performed without a BAV and this results in reduced procedural and fluoroscopic times, although embolization to the brain is not reduced. There is a trend toward reduced stroke risk. (J Interven Cardiol 2016;29:319-324).
