Annular ellipticity alone did not predict adverse outcomes, but moderate valve oversizing yielded the most favorable results in transcatheter aortic valve implantation.
Does annular ellipticity and sizing strategy impact adverse outcomes and device success in patients undergoing TAVI?
In TAVI, moderate oversizing yields the most favorable results, whereas annular ellipticity alone does not predict adverse outcomes.
Annular ellipticity alone did not predict adverse outcomes. While exploratory analysis suggested reduced device success in patients with both high ellipticity and suboptimal sizing, no significant interaction was identified. Moderate oversizing was associated with the most favorable results.
Polat et al. (2026) studied this question. Annular ellipticity alone did not predict adverse outcomes, but moderate valve oversizing yielded the most favorable results in transcatheter aortic valve implantation.
