Why the study?
Infolding of self-expanding transcatheter aortic valves is a rare complication that can precipitate cardiac arrest, requiring heightened vigilance and refined intervention strategies.
Case Report (n=1)
This case highlights the critical importance of rapidly recognizing self-expanding valve infolding during TAVR and managing it with immediate balloon postdilation alongside mechanical circulatory support.
May enable rescue of rare TAVR valve infolding with balloon dilation plus MCS; leaves open standardized protocols pending larger series.
Transcatheter aortic valve repair (TAVR) presents a minimally invasive alternative to traditional surgical valve replacement, albeit not without its own set of complications. A rare complication is the infolding of the self-expanding valve, which can precipitate cardiac arrest. The estimated incidence rate of this complication stands at 1.6%. The management of this complication hinges on either balloon dilation or valve replacement. This article discusses a case involving a 78-year-old man with symptomatic severe aortic valve stenosis. Following TAVR, the patient experienced asystole due to valve infolding, highlighting the need for heightened vigilance and refined intervention strategies in the management of TAVR complications.
