Balloon Aortic Valvuloplasty Prior to Self‐Expanding TAVI: The BAVSE‐TAVI Registry
Why the study?
Certain clinical and CT-based characteristics might indicate the need for balloon aortic valvuloplasty before TAVI, but which patients require predilatation before self-expanding TAVI remained unclear.
Does balloon aortic valvuloplasty prior to self-expanding TAVI improve procedural safety and outcomes compared to direct TAVI in patients undergoing TAVI?
Population
315 patients undergoing TAVI (predilatation = 158 vs. direct = 157)
Comparison
Predilatation before TAVI vs direct TAVI
Design
Retrospective, single-center study

Overview
CT features may guide selective predilatation before TAVI; leaves open need for prospective validation.
Structured PICO
Does balloon aortic valvuloplasty prior to self-expanding TAVI improve procedural safety and outcomes compared to direct TAVI in patients undergoing TAVI?
P
Population
315 patients undergoing self-expanding transcatheter aortic valve implantation (TAVI), mean age 81 ± 6 years, 43.5% male, mean EuroSCORE II 3.7 ± 2.9.
I
Intervention
Balloon aortic valvuloplasty (predilatation) prior to self-expanding TAVI
C
Comparator
Direct self-expanding TAVI (without predilatation)
O
Outcome
Procedural outcomes including valve recapture, embolization, contrast use, procedure duration, hospital stay, inpatient death, stroke, significant paravalvular leak, new pacemaker implantation, and BARC ≥ 3 bleedingsafety
Both predilatation and direct-TAVI approaches are safe, but direct-TAVI was associated with a higher rate of BARC ≥ 3 bleeding, and horizontal aorta independently predicted the need for predilatation.
