Key result
Balloon valvuloplasty successfully reverses severe self-expandable transcatheter aortic valve infolding, restoring geometry and function.
Why the study?
Infolding of the valve stent frame is a rare complication of self-expanding transcatheter heart valves causing malapposition, perivalvular aortic insufficiency, and leaflet dysfunction.
Case Report (n=1)
Balloon valvuloplasty may offer a bailout for severe THV infolding; Level 5 evidence leaves open reproducibility and safety in broader use.
Transcatheter aortic valve replacement is an approved treatment for select patients with severe aortic stenosis. A rare complication of self-expanding transcatheter heart valves (THVs) is infolding of the valve stent frame, which results in a malopposed segment, perivalvular aortic insufficiency, and possibly leaflet dysfunction. We report here a successful case of balloon valvuloplasty treatment for severe infolding of a self-expandable THV in the aortic position, restoring stent frame geometry and leaflet function.

Kaple et al. (2015) conducted a case report in Severe infolding of a self-expandable transcatheter heart valve (n=1). Balloon valvuloplasty was evaluated on Restoration of stent frame geometry and leaflet function. Balloon valvuloplasty successfully treated severe infolding of a self-expandable transcatheter heart valve in the aortic position, restoring stent frame geometry and leaflet function.
