ABSTRACT
BACKGROUND:
For patients with borderline annulus areas that fall between two valve sizes, overinflating a smaller balloon-expandable transcatheter heart valve (THV) may be preferable to nominal sizing of a larger THV.OBJECTIVES:
To evaluate the outcomes of nominal preparation versus over-expanding an under-sized SAPIEN 3 Ultra (S3U) transcatheter heart valve (OE-THV) in cases with borderline annuli.METHODS:
958 patients that underwent TAVR with the S3U at four high-volume TAVR centers between January 2017 and December 2020 were retrospectively reviewed. 336 patients were identified as borderline annuli size, of which 146 (44%) received OE-THVs and 190 (56%) received nominal-sized THVs. The primary composite endpoint included in-hospital mortality, aortic injury, moderate/severe paravalvular leak (PVL), permanent pacemaker implant (PPM), stroke, or conversion to surgery.RESULTS:
Baseline characteristics were similar except for a larger percentage of females in the OE-THV (53.42% vs. 42.11%, p = 0.04). TAVR with OE-THV resulted a reduction in the primary composite endpoint (13.69% vs. 22.63%, p = 0.04). On subgroup analysis, there was no difference between 20 mm OE-THV versus 23 mm nominal or 23 mm OE-THV versus 26 mm nominal, but there was a reduction in the primary composite endpoint in patients with larger annuli that received a 26 mm OE-THV compared to the 29 mm nominally sized THV (9.7% vs. 27.4%, p = 0.02). At 1 month and 1 year follow-up, there was no significant difference in mortality, PVL rates, NYHA class, and/or KCCQ score.CONCLUSION:
Overinflating a smaller-sized S3U THV may be a safer option in comparison to nominal sizing in patients with borderline annular area.Palavras-chave
